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_bindingRegionsOnly.md.tpr -o
NNODES=2, MYRANK=0, HOSTNAME=quoVadis01
NNODES=2, MYRANK=1, HOSTNAME=quoVadis04
but it comes up with
connect() failed: No route to host (113)". The CPUs are calculating on
both (physically different machines) but unfortunately no results are
Was the port redirection of 22 not enough or is there another problem?

come on, it must be somehow possible to use openmpi not on port 22!? ;-)
