I'm trying to run MPI program on MIC and host at the same time, but it get stuck and nothing reported. So I use ctrl+c to stop it.
I followed the below article:
The command I use is as follows:
Situation 1: 172.31.1.254 is the CPU part, and this is fine.
$ mpiexec.hydra -host 172.31.1.254 -n 2 ./a.out Hello world: rank 1 of 2 running on Tsinghua3MIC
Hello world: rank 0 of 2
Situation 2: 172.31.1.1 is the MIC card, and it gets stuck. Nothing appears.
$ mpiexec.hydra -host 172.31.1.1 -n 2 -wdir /home/pacman ./a.out.mic
I also try to use both.It also gets stuck. Could anyone help?
$ mpiexec.hydra -host 172.31.1.254 -n 1 ./a.out : -host 172.31.1.1 -n 2 -wdir /home/pacman ./a.out.mic
