[mpich-discuss] multiple mpd rings as one user

[oliver.wissdorf at boehringer-ingelheim.com]

Hello,

I want to start multipel rings as one user on a linux cluster to submit more
than one job at a time. Therefore I use mpdboot and mpdexec:



/usr/mpi/gcc/mvapich2-1.0.2/bin/mpdboot  -n 17 -f $PWD/mpd.txt --verbose
--ifhn=172.17.30.101

/usr/mpi/gcc/mvapich2-1.0.2/bin/mpiexec -machinefile $WORKDIR/mpd.txt -n $np
<jobscript>

I tried to set MPD_CON_EXT before starting the mpdboot and this allows me to
start multiple mpds on the host where the ring starts, but not on the other
hosts of the ring.
I also tried to use -1 option with mpdboot, but this did not work either.

Is there a way to solve this issue? Did I make any mistakes?

Oliver
