	Hi! Why is the GPU Load only about 43% when running ACEMD - GPU molecular dynamics 6.03 (cuda)? http://img222.imageshack.us/i/cudatoimii17.png/ The GPU card is ASUS GTX 275 PCI Express 2.0 x16. My motherboard only has a PCI Express 1.x x16 slot. The CPU is a dual-core Pentium D 920. Is my PC a bottleneck or is it normal to not have a 100% GPU load when running ACEMD? ____________

	Why is the GPU Load only about 43% when running ACEMD - GPU molecular dynamics 6.03 (cuda)? Don't put too much faith in "GPU Load" measurements of this sort for GPUGRID - the quantity measured is only a reliable estimate of GPU use by graphics, not by a CUDA program. MJH
