<t>I haven't done extensive testing regarding the relationship between reliability and ECC. However, the On the Tesla C2050 I've been using for only for testing/benchmarking and no production runs the ECC Error count is far from 0, a great part of it must have occurred while running Gromacs with Ope...

The nvidia-smi tool (NVIDIA System Management Interface), distributed with the drivers, provides memory usage information. Moreover, the new 270.x drivers don't display the memory usage in percentage anymore, but provide the actual amount of memory used.

Actually, based on my recent benchmarks, the GTX 580 is up to 50% faster than the C2050 with ECC off, while with ECC on the difference is as high as 58%. Check this: http://goo.gl/zHMY
