Dear lam/mpi list
I use LAM/MPI 7.0.6-4 (url for source see below) which I recompiled
from source, because the Debian package strips symbol information and
therefore does not work with the TotalView debugger. (Would be a good
idea to mention that to the Debian package builders too)
I observe the following odd behaviour (which I did not have with the
7.0.6-2 Debian binary package from the Debian package archive). FYI:
ring is the ring example application from the lam examples:
******************************************
LAM 7.0.6/MPI 2 C++/ROMIO - Indiana University
e3050_at_platosrv:~/workspace/lam-examples/examples/main/ring$ mpirun
n0,0,0,0 ring
-----------------------------------------------------------------------------
The selected RPI failed to initialize during MPI_INIT. This is a
fatal error; I must abort.
This occurred on host
platosrv-----------------------------------------------------------------------------
(n0The selected RPI failed to initialize during MPI_INIT. This is a
).
fatal error; I must abort.
The PID of failed process was 1076
(MPI_COMM_WORLD rank: 0)
-----------------------------------------------------------------------------
This occurred on host platosrv (n0).
The PID of failed process was 1077 (MPI_COMM_WORLD rank: 1)
-----------------------------------------------------------------------------
-----------------------------------------------------------------------------
One of the processes started by mpirun has exited with a nonzero exit
code. This typically indicates that the process finished in error.
If your process did not finish in error, be sure to include a "return
0" or "exit(0)" in your C code before exiting the application.
PID 1078 failed on node n0 (147.50.18.157) with exit status 1.
-----------------------------------------------------------------------------
********************************************
If I use only 3 processes on the same node, i.e, mpirun n0,0,0 ring
things work.
I had applications which even only runned with 2 processes on the
"root node".
I also have to do a lamhalt / lamboot hostfile sequence to do mpirun
again without errors once I got errors like above.
I somewhere stumbeled over a not of Jeff that such errors are going to
be fixed in lam 7.1.x.
Do I need to switch to version 7.1.x.
A quick answer will be very much appreciated.
Binary source which I recompiled:
