I still try to study about cusolverMG library.
My workstation has 4 K80C cards. nvidia-smi command tells me that 11441MB memory is available for each GPU core. I’ve tried the example code in cuSOLVER :: CUDA Toolkit Documentation. I’ve watched the memory usage while running the code and found that core 0 uses 907MB and the other 7 cores use 112MB memory after run cusolverMgDeviceSelect routine. I didn’t allocate any memory at the moment. My question is as follows:
-
What does the cusolverMgDeviceSelect do internally?
-
Why does it allocate memory inhomogeneously?
Please help.
