CUDA Sample "Bandwidth Test" does not include GPU RAM to GPU Processor.


It could be interesting if NVIDIA could add another test mode for the CUDA (programming) Sample (example) called “Bandwidth Test”.

I checked the sample from cuda toolkit 5.5 (utilities).

This sample only tests “hosts to device”, “device to host” or “device to device”. (And variations of pinned/unpinned memory etc).

But it does not actually test the bandwidth from GPU RAM to GPU Processor (reading) or GPU Processor to GPU RAM (writing).

A new mode to test such a situation would make the bandwidth test more complete ?!

Something which will also interest many ! ;)
