[mpich-discuss] mpiexec -hosts option

[Graeme Hilton]

Hi,

I've got a cluster of three Linux machines; node01 node02 and node03.

node01 has 8 CPUs while node02 and node03 have 4 CPUs each.

I've got an mpd ring running with "mpdboot -n 3 -f /etc/mpd.hosts" where the
mpd.hosts file lists node02 and node03.

I'd like to run the following command:
mpiexec -hosts 16 node01 8 node02 4 node03 4 /bin/hostname
and I get the following error:
invalid "local" arg: -hosts

According to the documentation I have (1.1.1p1) this is a valid argument.

Any hints?
