Re: [OMPI users] problem running Open MPI on Cells

Where did you put the environment variable related to MCF licence file and MCF share libraries? What is your default shell? Did you test indicate the following? Suppose you have 4 nodes, on node 1, " mpirun -np 4 --host node1,node2,node3,node4 hostname" works, but "mpirun -np4 --host

Re: [OMPI users] Problem with openmpi version 1.3b1 beta1

I see you are using IPv6. From what I can tell, we do enable that support by default if the underlying system supports it. My best guess is that either that support is broken (we never test it since none of us use IPv6), or our configure system isn't properly detecting that it exists.

Re: [OMPI users] problem running Open MPI on Cells

Hi, To monitor the environment from inside the application, it could be useful to issue a 'system("printenv")' call at the very beginning of the main program, even before (and after, btw) the MPI_Init call, when running in serial job mode with a single CAB, using mpirun. HTH,

Re: [OMPI users] Equivalent .h files

The Open MPI that ships with Leopard does not include Fortran support because OS X does not ship with a Fortran compiler (this was Apple's decision, not ours). If you have Fortran MPI applications, you'll need to a) download and install your own Fortran compiler (e.g., http://hpc.sf.net/)
