<html><P>Ah now I see my mistake. In mpdboot -n 2, n stands for number of hosts, <BR>but in mpiexec it is number of processses... It works with<BR><BR>mpdboot -n 2<BR>mpiexec -n 4 prog<BR><BR>when I have uncommented styx in the mpd.hosts. And I would run "mpdboot <BR>-n 1" together with "mpiexec -n 2 prog" to use both cores on only one <BR>machine.<BR><BR>Sorry for the noise... :-)<BR><BR>Best regards<BR>Torquil Sørensen</P>
