Although I have seen quite a bit of discussion about this error message (The selected RPI failed to initialize during MPI_INIT message), I didn't see anything that addresses my situation.
I am running on a Mac Intel dual-core laptop. I successfully installed LAM MPI and have been running it for a few weeks. Here is the info from lamboot -V:
LAM 7.1.3/MPI 2 C++/ROMIO - Indiana University
Arch: i386-apple-darwin8.8.2
Prefix: /usr/local
Configured by: maherou
Configured on: Tue Mar 13 19:48:11 CDT 2007
Configure host: herouxmac.local
SSI rpi: crtcp lamd sysv tcp usysv
However, just today programs that I compiled and ran correctly last week no longer work. I get the following message:
-----------------------------------------------------------------
The selected RPI failed to initialize during MPI_INIT. This is a
fatal error; I must abort.
This occurred on host herouxmac (n0).
The PID of failed process was 25633 (MPI_COMM_WORLD rank: 0)
-----------------------------------------------------------------
I have rebooted my machine to make sure that there weren't problems with system resources.
The only things I can say have changed are that I installed some new software yesterday, in particular Matlab.
I am able to run my codes if I specify the RPI, e.g., "mpirun -ssi rpi crtcp ..." . It appears that modes crtcp, lamd and tcp work, but sysv and usysv do not.
This is not a critical problem for me now, since I can run my programs, but I am puzzled about how the behavior changed.
