[HTCondor-users] MPI process manager and Condor not understanding each other?

[Patricia Bittencourt <patricia.bsampaio@xxxxxxxxx>]

Hello,

      I'm trying to run mpi applications using more than one node through condor. But so far no luck. 

      If I'm not wrong condor_ssh script should be used and it is not. Instead of that, node 0 is trying to launch hydra_pmi_proxy to the other nodes. And that is when the problems start. 

      First, the keys created by sshd.sh in condor, are not being used. Only after adding a ssh key generated outside condor, in a regular authorized_keys file, node 0 could connect to the remote node 1. 

      Now, the following error happens:

[proxy:0:1@xxxxxxxxxxxxxxxxx] launch_procs (./pm/pmiserv/pmip_cb.c:651): unable to change wdir to /opt/condor-7.2.4/local.nc14/execute/dir_14220 (No such file or directory)

       nc14 runs node 0 in that case while nc08 runs node 1. 

       May I have something misconfigured? I wonder if hydra works at all with Condor... 

       What are your suggestions here?

       Advice is highly appreciated. 

Thanks,

Patricia
