pmi_proxy not found

Paul_Fons — Thu, 29 May 2014 04:24:05 GMT

Hi,

I have installed under CentoOS 6.5 (latest release), the latest as of this writing intel mpi system and compilers l_mpi_p_4.1.3.049 and parallel_studio_xe_2013_sp1_update3. This is on a Dell T620 system with an 24 cores (Ivy Bridge 12 cores x 2 Cpus). I have four of these nodes and I am not having the same sort of trouble for the other nodes as this one. I have reproduced the trouble below, namely when I attempt to start a process using mpi hydra, it always hangs with the error "pmi_proxy: No such file or directory". On the other hand if I use the mod system, the program (in this case the ab-initio calculation software VASP) starts up and runs without trouble. I have reinstalled both the mpi and compiler systems and I am have no idea what is causing this problem. Another symptom is that trying a simple diagnostic such as "mpirun -n 24 hostname" and mpiexec -n 24 hostname" produce different results. While mpirun results in the same hang with pmi_proxy, mpiexec runs fine (reproduced below). On the other nodes, "mpirun -n 24 hostname" prints out the hostnames as expected.

Any suggestions as to how to fix this would be gratefully appreciated.

What is the output from

What is the output from

env | grep I_MPI

The result from "env | grep I

Paul_Fons — Sun, 01 Jun 2014 23:08:08 GMT

The result from "env | grep I_MPI" is the same as that from the other machines in the cluster that do not have this problem:

I_MPI_FABRICS=shm:ofa

I_MPI_ROOT=/opt/intel/impi/4.1.3.049

Try running with I_MPI_HYDRA

James_T_Intel — Mon, 02 Jun 2014 15:17:06 GMT

Try running with I_MPI_HYDRA_DEBUG=1 and attach the output.

Do you have /opt/intel

James_T_Intel — Tue, 26 Aug 2014 13:10:57 GMT

Do you have /opt/intel available via NFS on the coprocessor? If not, you will need to ensure that pmi_proxy (along with whichever MPI libraries you have linked) is available in the path on the coprocessor.

I found a fix!

This page didn't really help me, but I think I found a solution so I thought I'd post it.

I found that setting the I_MPI_MIC_PROXY_PATH environment variable to the directory in which the pmi_proxy command for the MIC resides (on the MIC itself) corrects this issue!

HTH,

Jim
