dmpirun failure across two Compaq ES45's

[Volker Blum]

Hi all,

we are trying to run an (otherwise working) MPI application across different machines, using a host files. To be precise, we use the syntax

dmpirun -hf ./host_file -np 2

The answer is

[ 0] MPID Die - ump2main.c:513 "ump_init failure" (-1)
[ 1] MPID Die - ump2main.c:513 "ump_init failure" (-1)
MPI process 178573 exited with status 255
MPI process 458406 exited with status 255

Sad, isn't it?

The thing works fine when only one host is specified in the host file, but as soon as communication with the remote machine is attempted, it fails. Trusted rsh is enabled.

We tried several variants and are now out of ideas. Any hints as to what we could be missing would be appeciated.

Best,
Volker Blum
