How to multithread in AWS with MPI?

Post by ceducation » Sun Jul 22, 2018 6:08 pm

Hello all,

I am trying to run mpirun in an AWS instance with the abinit executable, like such:

mpirun -np 10 abinit <______.files> log

However, when I check top, only one processor seems to be running. Do you all think this could be a configuration with abinit issue or an AWS issue? If it is configuration with abinit, what steps should I take to ensure that mpirun works as intended?

Thanks a lot!
