Hello,
I have a workstation with 2 CPU and 2 GPU. I downloaded
NAMD_Git-2021-03-03_Linux-x86_64-multicore-CUDA and tried to compile it
with the below options, I want to use all GPU for a single CPU or both the
CPU and GPU in the workstation.
1) namd2 +p18 +idlepoll stmv.namd +setcpuaffinity +isomalloc_sync
2) namd2 +idlepoll +p4 +devices 0,1 <configfile>
*But getting the same error*
Charm++> Running on 1 hosts (2 sockets x 10 cores x 2 PUs = 40-way SMP)
Charm++> cpu topology info is gathered in 0.006 seconds.
Info: Built with CUDA version 10010
FATAL ERROR: CUDA error cudaGetDeviceCount(&deviceCount) in file
