The system has about 3k atoms, and I used a rhombic dodecahedron box.
The node in the cluster has 2 sockets and 12 cores per socket. (24 sockets
It also has 4 gpu.
Will I waste cpu time, if I run with all 24 cores and assign 1 gpu to 3
Should I compile for mpi?
Alternatively, I can run with just 12 cores and assign 1 gpu to every 3
The remaining 12 cores and 2 gpu will be used by another user.
Which way is a more efficient use of time per cpu core?
