[OMPI users] Mac OS X 10.4.5 and XGrid, Open-MPI V1.0.1

[Frank]

XGRID_CONTROLLER_HOSTNAME and XGRID_CONTROLLER_PASSWORD are properly set 
up, Open-MPI 1.0.1 is installed on all machines (with the same configure 
options). When configured with --prefix=/usr/local/openmpi my app is 
supplied to the xgrid controller and I can see that copy's of my app are 
"supplied" to the other machines, too - but the jobs hang, nothing 
happens (user nobody has full access to the folder /usr/local/myapp 
where my app is run). /usr/local/openmpi/bin and /usr/local/openmpi/lib 
are added to the variables PATH and DYLD_LIBRARY_PATH on every machine, 
too. I'm running into this situation no matter from which machine my app 
ist started. To the guys with openmpi and xgrid performing correct: 
which configure options did you use? The firewall is told not block any 
internal traffic on the subnet. When not using the xgrid my app performs 
correct.

Has anyone any idea concerning this matter?
