[mpich-discuss] multiple mpd rings as one user<BR></FONT><BR></DIV>
<DIV></DIV><!-- Converted from text/rtf format -->
<P><FONT face=Arial size=2>Hello,</FONT> </P>
<P><FONT face=Arial size=2>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:</FONT></P><BR><BR>
<P><SPAN lang=de><FONT face=Arial
size=2>/usr/mpi/gcc/mvapich2-1.0.2/bin/mpdboot -n 17 -f $PWD/mpd.txt
--verbose --ifhn=172.17.30.101</FONT></SPAN> </P>
<P><SPAN lang=de><FONT face=Arial
size=2>/usr/mpi/gcc/mvapich2-1.0.2/bin/mpiexec -machinefile $WORKDIR/mpd.txt
-n $np <jobscript></FONT></SPAN> </P>
<P><SPAN lang=de><FONT face=Arial size=2>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.</FONT></SPAN></P>
<P><SPAN lang=de><FONT face=Arial size=2>I also tried to use -1 option with
mpdboot, but this did not work either.</FONT></SPAN> </P>
<P><SPAN lang=de><FONT face=Arial size=2>Is there a way to solve this issue?
Did I make any mistakes?</FONT></SPAN> </P>
