Hi everyone.

I have a cluster with G5 xserve cluster nodes. System is MacOSX server
10.3.9,
the switch is a GigE Asante (G52400W); lam-mpi version 7.1.1 was
compiled with xlf/xlc.

Everything works fine with the default network settings for the nodes.

As soon as I try larger MTU than 1500, the lam-mpi environment fails to
start:
lamboot hangs forever.

I guess -and I hope- it is not, strictly speaking, a lam-mpi problem.
Did I miss something in the FAQ ? Any suggestion ?
