I upgraded recently to gcc-4.3 and I'm finding trouble to execute my MPI
programs. Indeed, when executing an MPI program with mpiexec sometimes it
terminates correctly and sometimes it shows different error messages such
as:
rank 2 in job 1 mahmoud-desktop_33023 caused collective abort of all
ranks
exit status of rank 2: killed by signal 9
or
[cli_1]: aborting job:
Fatal error in MPI_Allreduce: Other MPI error, error stack:
MPI_Allreduce(696)........................: MPI_Allreduce(sbuf=0x8103344,
rbuf=0x8103348, count=1, MPI_UNSIGNED, MPI_SUM, MPI_COMM_WORLD) failed

rank 3 in job 4 mahmoud-desktop_33023 caused collective abort of all
ranks
exit status of rank 3: killed by signal 9
rank 0 in job 4 mahmoud-desktop_33023 caused collective abort of all
ranks
exit status of rank 0: killed by signal 11
I'm failing to find a reason as my programs work fine with gcc 4.2. If it
is
a known bug that has been already fixed please send tell me how to fix it
on
my own machine.
Best regards,
Yours faithfully.
