	I don't see anything new on https://www.gpugrid.net/apps.php yet? OT, but I've always found it weird that this link is not linked from anywhere on the main GPUGRID site. can only find it via a google search or previous bookmark. if you're just browsing through the GPUGRID site it doesn't exist. ____________

	Thanks. You’re right it’s there. But I’ll follow up that it’s a very odd place for it. Nearly all other BOINC project puts a link near/with credit statistics, directly on the main page, or as a link on the bottom of every page. ____________

	Why are you not running more test tasks for the new app? Almost all of the tasks ended on one of Ian’s hosts … or is that enough feedback for now? Anyway, credit calculation looks almost random to me. At least for these tasks. Any chance you will fix that before this gets into production? (Comparison: 700sec runtime awarded ~100k vs. admittedly lower end card 110k sec runtime getting 565k credit. Seems out of scope.

	wow, I didnt even notice, I was out all day. I just set the system (7x GPU) to check for work every 100s or so and only checking for beta GPU work, so it doesn't surprise me that it got so many. it would ask for 7 at once, and I guess it got lucky that it asked for some work before anyone else. beta tasks have always paid a lot of credit here for some reason. but as with previous beta tasks, I see no indication that these tasks actually did anything on the GPU. my guess is that they ran some stuff on the CPU then finished. I've asked before what their intentions are with these tasks, and it's clear they are doing some type or machine learning kind of thing, but they dont appear to be even using the GPU at all, which is very strange when they are labelled as a cuda app. ____________

	The Obstacle Tower environment is a simulated environment for machine learning (Reinforcement Learning) research. Note that in order to research how to train and deploy embodied agents in the real word it is common to research in 3D world simulations like this on. This is the github page of the project: https://github.com/Unity-Technologies/obstacle-tower-env We use it as a testbench within our efforts to train populations of interacting artificial intelligent agents able to develop complex behaviours and solve complex tasks. The environment runs on GPU, and the Deep Learning models learning how to solve the simulation too. Most of the bugs we are trying to solve are related to the environment. It is installed via git, but the git-related issues is being solved from the server side as mentioned. The reported stderr message "ModuleNotFoundError: No module named 'aiohttp.signals'" should be solved now. The small black screen is also related to the environment. ____________

	Tried a LOT of the PythonGPU tasks today. Still no joy for a successful run. Think they are getting further along though since I think I see progress in how far they get before the environment collapses and errors out.

	Got another from what looks like the same batch. Limit is <max_nbytes>100000000.000000</max_nbytes> I'll catch the output and see how big it is. Edit - couldn't catch it ('report immediately' operated too fast). But I watched the next one in the slot directory: the output file was created right at the end, but was cleaned up almost immediately. I read it as 169 MB, but can't be certain.

	Well, I got one for you to study: e1a8-ABOU_PPOObstacle7-0-1-RND2466_3 That was done by manually increasing the maximum allowed size in BOINC. I think that's an internal setting in the BOINC system - specifically, the workunit generator or its template files - rather than the Python package. I've suspended work fetch for now - please let us know when the next iteration is ready to test. Edit - this it what the upload file contained: It seems a bit odd to return the ObstacleTower zip back to you unchanged?

	Haven't heard of any posts by admin types that Windows apps will be made. That stated, often the new beta apps are tested first on Linux to get the bugs out and then the Windows apps are generated.

Can an admin please directly comment if these are actually using the GPU or not? I know an admin mentioned that they were only doing CPU work "as a test". Is that still the case? Having GPU tasks that only use the CPU core is very confusing. ____________

	The ones that have partially ran and were validated only used 31% of the gpu in nvidia-smi. The one task that appears to have successfully run through to normal completion was done while I was out of the house and did not see it run unfortunately. Will have to wait for more to observe.

	Looks like the tasks fluctuate between a few seconds at 1% utilization before returning to hovering around 10-13% utilization. I was watching one on a 2070 and it was running for almost 60 minutes in nvidia-smi. They are marked at C+G type in that program. I think I killed it when I pulled up htop to look at how much cpu it was using because it finished with an error instantly at the same time as htop populated the screen.

	The contents of the obstacletower.zip downloaded file are necessary to generate the data required for the machine learning agent to train. That is why the file itself is not modified. Only used to generate the training data. The expected behaviour is for the file to be downloaded, used during the job completion and then deleted. Should not be returned. Some jobs have already finished successfully. Thank you for the feedback. Current jobs being tested should use around 30% GPU and around 8000MiB GPU memory. ____________

	That's the next bad news for me as my GPU is maxed out at 6GB. Without upgrading my GPU and that's not likely gonna be soon, I suppose I have to give up on these types of tasks - at least for the time being. Thanks for the update though

	I can only speculate in regards to the former one. But your latter question likely resolves to 8,000 MiB (Mebibyte) which is just another convention to count bits – if he indeed meant to write 8,000. While k (kilo), M (Mega), G (Giga) and T (Tera) are the SI-prefix units and are computed as base 10 by 10^3, 10^6, 10^9 and 10^12 respectively, the binary prefix units of Ki (Kibi), Mi (Mebi), Gi (Gibi) and Ti (Tebi) are computed as base 2 by 2^10, 2^20, 2^30 and 2^40. As such M/Mi = (10^6/2^20) ~ 95.37% or a difference of ~4.63% between the SI and binary prefix units. 1 kB = 1000 B 1 KiB = 1024 B

	ah, all right. didn't mean to offend you if that's what I did. still don't understand their beta testing procedure anyway. so far not many tasks have been run, only few of them successfully, but meanwhile nearly no information has been shared rendering the whole procedure rather intransparent and leaving others in the dark wondering about their piles of unsuccessful tasks. and the little information that is indeed shared seems to conflict a lot with the user experience and observations. for a ML task 8 GB isn't untypical though

	I agree that lots of memory use wouldnt be atypical for AI/ML work. and also agree that the admins should be a little more transparent about what these tasks are doing and the expected behaviors. it seems so far they have tons and tons of errors, then the admins come back and say they fixed the errors, then just more errors again. I'd also like to know if these are using the Tensor cores on RTX GPUs. ____________

	I think the Beta testing process is (as usual anywhere) very much an incremental process. It will have started with small test units, and as each little buglet surfaces and is solved, the process moves on to test a later segment that wasn't accessible until the previous problem had been overcome. Thus - Abouh has confirmed that yesterday's upload file size problem was caused by including a source data file in the output - "Should not be returned". I also noted that some of Keith's successful runs were resends of tasks which had failed on other machines - some of them generic problems which I would have expected to cause a failure on his machine too. So it seems that dynamic fixes may have been applied too. Normally, a new BOINC replication task is an exact copy of its predecessor, but I don't think can be automatically assumed during this Beta phase. In particular, Keith's observation that one test task only used 200 MB of GPU memory isn't necessarily a foolproof guide to the memory demand of later tests.

I'm just wondering if it's a typo, Keith ran some of these beta tasks successfully and did not report such high memory usage, he claimed it only used about 200MB Yes, I have watched tasks complete fully to a proper boinc finish end and I never saw more than 290MB of gpu memory reported in nvidia-smi at a max 13% utilization. Unless nvidia-smi has an issue in reporting gpu RAM used, the 8GB of memory post is out of line. Or the tasks the scientist-developer mentioned haven't been released to us out of the laboratory yet.

	We are progressing in our debugging and have managed to solve several errors, but as mentioned in a previous post, it is an incremental process. We are trying to train AI agent using reinforcement learning, which generally interleaves stages in which the agent collects data (a process less GPU intensive) and stages in which the agent learns from that data. The nature of the problem, in which data in progressively generated, accounts for a lower GPU utilisation that in supervised machine learning, although we will work to progressively make it more efficient once debugging is completed. Since the obstacle tower environment (https://github.com/Unity-Technologies/obstacle-tower-env), the source of data, also runs in GPU, during the learning stage, the neural network and the training data together with the environment occupy approximately 8,000 MiB (Mebibyte, was not a typo) of GPU memory when checked locally with nvidia-smi. Basically, the python script has the following steps: step 1: Defining the conda environment with all dependencies. step 2: Downloading obstacletower.zip, a necessary file used to generate the data. step 3: Initialising the data generator using the contents of obstacletower.zip. step 4: Creating the AI agent and alternating data collection and data training stages. step 5: Returning the trained AI agent, and not obstacletower.zip. Only after reaching step 4 and step 5 the GPU is used. Some of the jobs that succeeded but barely used the GPU were to test that indeed problems in step 1 and step 2 had been solved (most of them solved by Keith Myers). We noticed that most recent failed jobs returned the following error at step 3: mlagents_envs.exception.UnityTimeOutException: The Unity environment took too long to respond. Make sure that : The environment does not need user interaction to launch The Agents' Behavior Parameters > Behavior Type is set to "Default" The environment and the Python interface have compatible versions. We are working to solve it. If step 3 is completed without errors, jobs reaching steps 4 and 5 should be using GPU. We hope that helped shed some light on our work and the recent results. We will try to solve any further doubts and inform about our progress. ____________

	Thanks for the more detailed answer. regarding the 8GB of memory used. -which step of the process does this happen? -was Keith's nvidia-smi screenshot that he posted in another thread showing low memory use, from an earlier unit that did not require that much VRAM? -will these units fail from too little VRAM? -what will you do or are you doing about GPUs with less than 8GB VRAM, or even with 8GB? -do you have some filter in the WU scheduler to not send these units to GPUs with less than 8GB? ____________

It's certainly possible to set such a filter: referring again to Specifying plan classes in C++, the scheduler can check a CUDA plan class specification like if (!strcmp(plan_class, "cuda23")) { if (!cuda_check(c, hu, 100, // minimum compute capability (1.0) 200, // max compute capability (2.0) 2030, // min CUDA version (2.3) 19500, // min display driver version (195.00) 384*MEGA, // min video RAM 1., // # of GPUs used (may be fractional, or an integer > 1) .01, // fraction of FLOPS done by the CPU .21 // estimated GPU efficiency (actual/peak FLOPS) )) { return false; } } We last discussed that code in connection with compute capability, but I think we're still having problems implementing filters via tools like that.

	At step 3, initialising the environment requires a small amount of GPU memory (somewhere around 1GB). At step 4 the AI agent is initialised and trained, and a data storage class and a neural network are created and placed on the GPU. This is when more memory is required. However, in the next round of tests we will lower the GPU memory requirements of the script while debugging step 3. Eventually for steps 4 and 5 we expect it to require the 8G mentioned earlier. Keith's nvidia-smi screenshot showing a job with low memory use was a job that returned after step 2, to verify problems in steps 1 and 2 had been solved. ____________

	So was this WU https://www.gpugrid.net/result.php?resultid=32660133 the one that was completed after steps 1 and 2? Or after steps 4 and 5? I never got to witness this one in realtime. I had nvidia-smi polling update set at 1 second and I never saw the gpu memory usage go above 290MB for that screenshot. It was not taken from the task linked above. The BOINC completion percentage just went to 10% and stayed there and never showed 100% completion when it finished. Think that is an issue with BOINC historically.

	The environment and the Python interface have compatible versions. Is the reason why I was able to complete a workunit properly because of having my local python environment match the zipped wrapper python interface? I use several pypi applications that probably have setup the python environment variable. Is there something I can dump out of the host that completed the workunit properly that will help you debug the application package?

	We sent out some jobs yesterday and almost all finished successfully. We are still working on avoiding the following error related to the Obstacle Tower environment: mlagents_envs.exception.UnityTimeOutException: The Unity environment took too. long to respond. Make sure that : The environment does not need user interaction to launch The Agents' Behavior Parameters > Behavior Type is set to "Default" The environment and the Python interface have compatible versions. However, to test the rest of the code we tried with another set of environments that are less problematic (https://gym.openai.com/). The successful jobs used these environments. While we find and test a solution for the Obstacle Tower locally we will continue to send jobs with these environments to test the rest of the code. Note that reinforcement learning (RL) techniques are independent of the environment. The environment represents the world where the AI agent learns intelligent behaviours. Switching to another environment simply means applying the learning technique to a different problem that can be equally challenging (placing the agent in a different world). Thus, we will now finish debugging the app with these Gym environments simply because are less prone to errors and, once we know the only possible source of problems is the environment, consider solving others. ____________

	Thank you for the feedback. We had detected the error in https://www.gpugrid.net/result.php?resultid=32660448 but not the one in https://www.gpugrid.net/result.php?resultid=32660680 Having alternating phases of lower and higher GPU utilisation is normal in Reinforcement Learning, as the agent alternates between data collection (generally low GPU usage) and training (higher GPU memory and utilisation). Once we solve most of the errors we will focus on maximizing GPU efficiency during the training phases. ____________

	have you considered creating a modified app that will use the RTX (and other) GPU's onboard Tensor cores? it should speed up things considerably. https://www.quora.com/Does-tensorflow-and-pytorch-automatically-use-the-tensor-cores-in-rtx-2080-ti-or-other-rtx-cards I'm guessing in addition to making the needed configuration changes, you'd need to adjust your scheduler to only send to cards with Tensor cores (GeForce RTX cards, TitanV, Tesla/QuadroRTX cards from Volta forward) ____________

	We are using PyTorch to train our agents, and for now we have not considered using mixed precision, which seem required for the Tensor cores. It could be an interesting possibility to reduce memory requirements and speed up training processes. I have to admit that I do not know how it affects performance in reinforcement learning algorithms, but it is an interesting option. ____________

	I've got several GPU Python beta tasks at my triple GPU Host #480458 Several of them have succeeded after around 5000 seconds execution time. But three of these tasks have exceeded this time. Task e1a20-ABOU_ppod_gym_test-0-1-RND4563_6 failed after 11432 seconds. Task e1a6-ABOU_ppod_gym_test-0-1-RND1186_1 failed after 18784 seconds. Task e1a2-ABOU_ppod_gym_test-0-1-RND2391_3 is currently running even longer. This last task is theoreticaly running at device 1. But it seems to be effectively running at device 0, sharing the same device with an ACEMD3 regular task e14s132_e10s98p1f905-ADRIA_AdB_KIXCMYB_HIP-0-2-RND7676_5.

	The excessively long training time problem and the problem related to FileNotFoundError: [Errno 2] No such file or directory: '/var/lib/boinc-client/slots/3/model.state_dict.73201' Have been fixed now. Most jobs sent today are being completed successfully. The reported issues were very helpful for debugging. Progress: The core research idea is to train populations of reinforcement learning agents that learn independently for a certain amount of time and, once they return to the server, put their learned knowledge in common with other agents to create a new generation of agents equipped with the information acquired by previous generations. Each GPUgrid job is one of these agents doing some training independently. In that sense, the first 4 letters of the job name identify the generation and the number of the agent (i.e. e1a2-ABOU_ppod_gym_test-0-1-RND2391_3 refers to the epoch or generation number 1 and the agent number 2 within that generation). The debugging done recently, has allowed more and more of this jobs to finish. An experiment currently running has achieved already a 3rd generation of agents. As mentioned in an earlier post, we are working now with OpenAI gym environments (https://gym.openai.com/) ____________

I have GPUGrid excluded from device 0, so I can run tasks from other projects in the faster PCIe slot while testing. But ... Well, despite running on the wrong card, it finished and passed the GPUGrid validation test. I've swapped over the exclusion, and BOINC and GPUGrid are now in agreement that card 0 is the card to use.

	Overnight, every of my currently active 6 varied Linux hosts received at least one task of the kind ...-ABOU_ppod_gym_test9-0-1-... All the tasks gave a valid result, none of them errored. This is promising! My triple-GPU host happened to receive several tasks in a short time, and three of them were executed concurrently. It catched my attention that there was observed a drastic change in overall system temperatures when transitioning from executing highly GPU/CPU intensive PrimeGrid tasks to the Gpugrid tasks. On the other hand, every GPU was effectively executing its own task, as shown at the following nvidia-smi screenshot: This confirms the Keith Myers observation that the previous task-to-GPU assignment problem in multi-GPU systems is solved. Well done!

	I can only guess the tasks are confused with the locally installed old Python 2.7 library with the bundle containing 3.8 Python. Python 2.7 is deprecated in current Linux distributions with minimum Python 3.6 in the distros now. You might want to either uninstall Python or upgrade it to the 3 series. I don't think uninstalling though is desired as I believe a lot of stock applications are Python based and you would lose those.

	I think you can uninstall python2 without damage. At least I could on Ubuntu 20.04.3, though I had only BOINC and Folding installed on it. But I then made the mistake of trying to purge all python versions. It made the system unbootable, and I had to re-install it.

	When I check python version on this PC I get 'Python 2.7.17'. On the PC that works, Python is not install at all. To discard that something is getting confused with the old, deprecated Python version, you can upgrade to Python 3 with the following Terminal commands: sudo apt install python-is-python3 sudo apt install python3-pip And after that, you can uninstall unnecessary old packages with the command: sudo apt autoremove

	I also have two closely similar Linux machines: 132158 508381 Don't be fooled by the host IDs: 132158 is an inherited ID from an earlier generation of hardware, and is actually slightly younger than 508381. Both run the same version of Linux Mint 20.2, installed from the same ISO download, and the same basic software environment - but I do make tweaks to the installed packages separately, as I encounter different testing needs. Yesterday, I was away from home, but both machines downloaded tasks from the ppod_gym_test9 batch. 132158 failed to run them, 508381 succeeded. The problem occurs during the learner.step in Python, with a ValueError raised at line 55 during initialisation: File "/var/lib/boinc-client/slots/4/gpugridpy/lib/python3.8/site-packages/torch/distributions/distribution.py", line 55, in __init__ raise ValueError( ValueError: Expected parameter loc (Tensor of shape (146, 8)) of distribution Normal(loc: torch.Size([146, 8]), scale: torch.Size([146, 8])) to satisfy the constraint Real(), but found invalid values: tensor([[nan, nan, nan, ..., nan, nan, nan], [nan, nan, nan, ..., nan, nan, nan], [nan, nan, nan, ..., nan, nan, nan], ..., [nan, nan, nan, ..., nan, nan, nan], [nan, nan, nan, ..., nan, nan, nan], [nan, nan, nan, ..., nan, nan, nan]], device='cuda:0', grad_fn=<AddmmBackward0>) The two 'file extraction' logs for the GPUGrid Python download seem to be different. I'll try to compare the software environment of the two machines and work out where the difference is coming from.

	Well, I've looked through the software installations for both machines, but I can't see any significant differences. Both have Python 3.8 installed (probably with the operating system), and no sign of any Python 2.x; I've installed a few sundries from terminal (libboost, git, some 32-bit libs for CPDN), but the same list on both machines. The 'file extraction' logs are different for every task, and sometimes the same filename appears more than once (is duplicated) in the list for a single task. For the tasks I ran successfully on host 508381, that was the only host that attempted them. The tasks that failed on host 132158 were issued to the full limit of 8 hosts, and failed on all of them. I can only assume that the difference between success and failure resulted from differences in the task data make-up, and not from differences in the installed software on my hosts.

So I followed the instructions here starting with Option 1 https://phoenixnap.com/kb/how-to-install-python-3-ubuntu At the end I did the python --version to check. Same 2.7.17 even though it seemed to complete. So I tried option 2 from source. That worked OK too with 3.7.5 I get to the end and see the note about checking for specific versions. Uh, oh. python --version = 2.7.17 python3 --version = 3.6.9 python3.7 --version = 3.7.5 So now I have 3 versions installed haha. Maybe one will work, dunno. But we'll need some more tasks to find out.

	sudo apt install python-is-python3 sudo apt install python3-pip Thanks, that worked and I now have python 3.8.10 installed on my two GG computers with cuda 11.4. I just noticed that one computer had previously attempted to run a python WU but it failed. https://www.gpugrid.net/result.php?resultid=32727968 The stderr said this among many other things: ==> WARNING: A newer version of conda exists. <== current version: 4.8.3 latest version: 4.11.0 Please update conda by running $ conda update -n base -c defaults conda I tried running that command but it said "conda: command not found." The rig that didn't run a python WU installed many more lines of files. The rig that did run the failed python WU installed less than half of the files. What are all of the prerequisites I need to run these python WUs?

I was hoping to get a response from the researcher before interfering with the process. Happy someone beat me to it. So once again we crunchers need to help along the process by installing missing software on our hosts to properly crunch the work the researchers are sending out. Would be nice if the researchers ran some of their work on some test systems of their own before releasing it to the public, or as we are also known as . . . "beta-testers"

	Hello everyone, sorry for the late reply. we detected the "cmake" error and found a way around it that does not require to install anything. Some jobs already finished successfully last Friday without reporting this error. The error was related to the atari_py, as some users reported. More specifically installing this python package from github https://github.com/openai/atari-py, which allows to use some Atari2600 games as a test bench for reinforcement learning (RL) agents. Sorry for the inconveniences. Even while the AI agents part of the code has been tested and works, every time we need to test our agents in a new environment we need te modify environment initialisation part of the code with the one containing the new environment, in this case atari_py. I just sent another batch of 5 test jobs, 3 already finished the others seem to be working without problems but have not yet finished. http://gpugrid.net/PS3GRID_ops/db_action.php?table=result&id=32730763 http://gpugrid.net/PS3GRID_ops/db_action.php?table=result&id=32730759 http://gpugrid.net/PS3GRID_ops/db_action.php?table=result&id=32730761 http://gpugrid.net/PS3GRID_ops/db_action.php?table=result&id=32730760 http://gpugrid.net/PS3GRID_ops/db_action.php?table=result&id=32730762 ____________

I wasn't asking you for a trivial response. I'm asking the people that create these work units why they don't specify 1 instead of 0.963. Because the GPUGrid staff don't set that figure. There's an algorithm in the (Berkeley written) BOINC server code which generates the figure to use from a range of outdated, stupid, data. I discussed this at some length almost three years ago, in https://github.com/BOINC/boinc/issues/2949 - with examples drawn from GPUGrid, among other projects. I think that this was about the point that Berkeley stopped reading a single word of what I write. Someone else can get to grips with it this time.

	thanks Richard, I had a thought that it was likely the output of some automated function within BOINC since nearly all projects end up with something like this by default if they don't manually set the figures. ____________

	Too bad they never worked to implement all or part of Richard's suggestion / GitHub issue. While I don't claim to be able to see the bigger picture in BOINC it sounds like a good path for automated adjustments when new GPU hardware is released.

	Were the very long ETA estimates intended to make GPUGRID Python GPU work run before any GPU work from other BOINC projects? They seem to be very good at doing that. Note there seems to be no thread for discussing non-beta Python tasks.

Note there seems to be no thread for discussing non-beta Python tasks. No not at all. BOINC just has no mechanism for dealing with hybrid cpu-gpu tasks. The Python on GPU tasks are the first of their kind. It will take the BOINC devs a lot of time to accommodate them correctly. If they are getting in the way of your other work, I suggest stopping them or limiting them to only a single task at any time by changing your cache size to absolute minimal values.

	FYI, the Python on GPU tasks are the same as the beta Python tasks currently. Both tasks are using the latest application code. The devs said they would still keep the beta plan class available, just not in use, for whenever a new application might be developed. So everyone is getting the standard Python work even if they have beta selected.

	Does anybody know how many cpu threads would be ideal to run them efficiently? I gave them 12 threads exclusively but still the task is run primarily on the cpu with my 3070ti kicking in only sporadically for a second or two.

	giving it more cores wont necessarily make it run faster. as few as 4 cores per task works fine on my EPYC system. but if you are running other projects on the CPU it will slow them down as the processes compete with each other for CPU time. by default the program will use however many cores you have and you really can't change this with any BOINC settings. also I would recommend putting Linux on that system instead of Windows. Linux runs much faster ____________

	Gotcha! My Linux Laptop finishes them in 10 hours, my much faster Windows PC needs 18! Thanks again Ian & Steve
