xGEMM

A collection of GEMM benchmarks to verify Summit V100 and Frontier MI-100/MI-200 GPUs.

using ROCM

Load up the AMD compiler on Spock:

module load rocm
module load craype-accel-amd-gfx908

Note both modules must be loaded for GPU offload to work.

The compiler flags for enabling GPU offload for OpenMP is the following:

CFLAGS = -fopenmp -target x86_64-pc-linux-gnu 		\
			-fopenmp-targets=amdgcn-amd-amdhsa   	\
			-Xopenmp-target=amdgcn-amd-amdhsa    	\
			-march=gfx908

To verify:

case 1

./mt-dgemm 10000
