1. Ralph, if I try to do my experiment with SGE, then it's the same
results with 1.4.2 as with 1.4.1.

Dear OpenMPI users
We built OpenMPI 1.4.1 on a new cluster and get the following error message
when starting a test job from the master node:

Yes. There is usually a difference between interactive logins and
non-interactive logins on which paths, etc. get set. Look in your shell
startup and see if there is somewhere that it exits early (or otherwise doesn't
process) for non-interactive logins.
In short: you need to ensure that your

Hello,
I've noticed that ompi-restart doesn't support the --rankfile option.
It only supports --hostfile/--machinefile. Is there any reason
--rankfile isn't supported?
Suppose you have a cluster without a shared file system. When one node
fails, you transfer its checkpoint to a spare node and in
Hi Jeff,
You were right. One of the other admins of the server I am working on, had a
script that runs the firewall every time I logged in. So even when I was
turning it off manually, the firewall ran the next time i logged in and hence
the error.
Thanks.

Hi All,
I keep getting an error about running out of MPI_TYPE_MAX and needing to set
the environment variable higher. What is this, and why is it happening? All of
the types and groups, etc that I create during my programs run are freed at the
appropriate times. Making this number 10x bigger ge
I don't think we have such an environment variable -- are you sure you're using
Open MPI?
The only reference to MPI_TYPE_MAX I see in the OMPI source tree is in the
ROMIO README file:

* When using ROMIO with SGI MPI, you may sometimes get an error
message from SGI MPI: ``MPI has run out o
