Let us know what happens.
By including --mca btl_tcp_if_include on the command line, the ring
program continues past the first round to completion. So even though
my non-ethernet interfaces were disabled (airport, firewire), one of
them seems to have been sufficiently active to get in the way. (In
fact, about a week ago I started to be suspicious of a hardware fault
on my PowerBook's airport card, and I have seen it attempting but
failing to make connections when it was supposedly disabled). The
Open MPI command line then is:
mpirun --hostfile mpi_hosts --mca btl_tcp_if_include en0 --np 2
mpi_test1
where en0 goes to the ethernet port on my PowerBook G4, and on to the
remote PowerMac.
How odd. That shouldn't happen -- we should be detecting that those
IP interfaces aren't active and then not use them.
Sorry for the hassle this caused you -- I'm glad we got you working,
but I'll poke around to see if we can't fix this properly so that you
don't need to specify btl_tcp_if_include (check out the FAQ for more
convenient mechanisms for specifying MCA parameters, such as in the
environment or in a file).
Thanks for the report!
