We have found a problem when trying to run jobs using tm when running  
on only one node.  Which is quite strange.  If the MPI library (Lam  
or OpenMPI)  uses 2 nodes (nodes=2:ppn=2)  the job will start just  
fine.  But if its 1 (nodes=1:ppn=2)  the job can not start.  This is  
not a problem for serial jobs,  we are also using the same versions  
of torque and lam/openmpi on our linux cluster with no problems.  If  
i build a LAM without tm support the jobs run fine.

I dug the archives and i found some references to a similar problem.   
Im just wondering what i should do to test it or if this is a known  
problem on OSX ?  The systems are running 10.3 on G5's,  its using
