I have an MPI program which runs with little to no problems under
lam 6.5.9. After upgrading to 7.0.3 the program now completes (all the
nodes stop executing) but does not exit. The program generates a large
amount of stdio output (status reports, etc, up to about a 12-13Mb file for
each run if redirected). If I redirect the stdio to a file, the file
continues to be updated albeit at a snail's pace. The same occurs if I dump
to a terminal, the program generates the data requested but doesn't complete
because (it appears) the stdio dump is not complete but is dumping to the
screen at a very slow rate.
I am lambooting my nodes with the default settings and I'm running
my program with mpirun -ssi rpi tcp. Has anyone experienced this or know
why this is occurring. Thanks.
