I have successfully compile HPL CUDA downloaded from NVIDIA site. My server use single GPGPU (M2075). When I run ./run_linpack first time I get error not enough GPGPU. I change P and Q value in HPL.dat to 1. I can successfully run ./run_linpack afterward.
When I check top, the CPU process is 100%. but using : nvidia-smi -q -g 0 -d UTILIZATION -l
GPGPU, CPU and memory usage is 0%. I would like to ask :
- Can I run HPL CUDA with 1 GPGPU per host?
- If I run HPL CUDA will the program use both CPU and GPGPU? or it will only use CPU?
- What is the correct way to use One GPGPU beside editing P & Q to 1 in HPL.dat?
Thank you all.
