I don't have any smart solution, but you can use the advice that I got
from Jeff when I was struggling to get LAM/MPI running under SGE: use
'lamboot -d' to get some debugging messages - although if you hit some
kind of race (which is likely), the mere printing of debugging
messages might make the problem go away...
Another idea is to run 'mpirun -v -sa -p bla ...' to get some more
details about what node fails to start.
And yet another idea, but I only took a look at the LAM 7.0.3 code, I
hope that it is still valid for later ones: before running lamboot,
define in the environment ((t)csh syntax):
setenv LAM_MPI_SSI_boot_base_promisc 1
