Hostfile to run abinit mpirun -np 32 -hostfile hosts ./abinit

Running Abinit Ground state
1

Hi,
After having struggled for many days to build abinit in my Xeon Ubuntu workstation… I am facing problems running it!
My workstation has 32 CPUs with two nodes (16 cores each). So far I can only use up to 16 cores.
If I use more I have to set a hostfile indicating the node name and the number of slots.
It’s clear that the number of slots is 16 each…but the problem is the node name/address???

Hi @samabdel, I am not sure what the problem is. Could you be more specific and give a MWE with error logs? It does not look like its a problem with abinit but rather a mpi one?
