Hi all,
anyone ever seen an error like this? Seems like I have some setting
wrong in opemmpi. I thought I had it setup like the other machines but
seems as though I have missed something. I only get the error when
adding machine "fs1" to the hostfile list. The other 40+ machines seem
fine.
It means you started the jobs ok (via ssh) but Open MPI wasn't able to
open TCP sockets between the two MPI processes. Open MPI needs to be
able to communicate via random TCP ports between its MPI processes.

I can't remember if I've forwarded this to the OMPI lists before;
pardon if you have seen this before. I have one of these books and I
find it quite handy. IMHO: it's quite a steal for US$25 (~600 pages).

Hey again,
I tried to build a work around via port redirection: iptables -t nat -A
PREROUTING -i eth1 -p tcp --dport 22 -j REDIRECT --to-port 5101
If I do that then I can start the job:
mpirun -np 2 -machinefile /home/bknapp/scripts/machinefile.txt mdrun
-np 2 -nice 0 -s 1fyt_PKYVKQNTLELAT
Hi Bogdan,
Thanks for the information and looking forward to the new OpenMPI feature of
port restriction...
About Debian, I was wondering about that...I've had no problems with it and I
was thinking everything was just done for me; of course, another possibility is
that there was no firewall

Perhaps it has something to do with RH's defaults for the firewall settings?
If your sysadmin uses kickstart to configure the systems, (s)he has to
add 'firewall --disabled'; similar for SELinux which seems to have
caused problems to another person on

it's not an issue of Open MPI but ssh. You need in your home a file
~/.ssh/config with two lines:
host *
port 1234
or whatever port you need.

Hi,
it shouldn't be necessary to supply a machinefile, as the one
generated by SGE is taken automatically (i.e. the granted nodes are
honored). You submitted the job requesting a PE?
