Re: [Condor-users] Parallel MPI Job

Hi Pat，

    I guess your job is running under user nobody, and mpd daemon needs to be started for each user on each machine.

Make sure that mpd daemon is started on the machine that run your job.

Subject: [Condor-users] Parallel MPI Job

Hi,

I'm trying to run a simple parallel MPI hello world on condor but I keep getting errors. My code works using mpirun. Here's my submit file:

universe = parallel

requirements = (TARGET.OpSys=="LINUX" && TARGET.Arch=="INTEL")

executable = mp2script

arguments = hello

log = hello.log

output = hello.out

error = hello.err

machine_count = 2

should_transfer_files = yes

when_to_transfer_output = on_exit

transfer_input_files = hello

+ParallelShutdownPolicy = "WAIT_FOR_ALL"

queue

And here's the error that I get from the generated files:

mpd.out.0:

/var/lib/condor/execute/dir_3282/condor_exec.exe: 60: /var/lib/condor/execute/dir_3282/condor_exec.exe: mpd: not found

mpd.out.1:

/var/lib/condor/execute/dir_5103/condor_exec.exe: 101: /var/lib/condor/execute/dir_5103/condor_exec.exe: mpd: not found

Any help would be appreciated. Thanks!

Regards,

Pat
