Hi Jiajun, all,
I have been performing some more tests.
When running the code with "mpirun_rsh -n 2 acme11 acme12 ./helloWorldMPI
", if I want to use DMTCP, there are problems (this is the scenario wof the
previus mail). Withouth the --ib flag the problem still persists. I think
the error is the same, below you have the output anyway.
In case it helps on the debug, some info that might be relevant:
- The application can be executed without DMTCP.
- With DMTCP, only the first node on the list is executed. But there seem
to be exceptions to this:
-- if I execute mpi_run sh with " -n 2 acme11 acme11" (or whatever
node, but the same one twice) : it crashes. This does not happen without
DMTCP, it that case it works correctly.
-- if I use " -n 3 acme11 acme12 acme11" (three nodes, repeating one):
it also crashes. It seems that if you put the same node more than once, it
does not work.
-- the first node in the list is the only one that runs. For example,
if I use "-n 2 acme11 acme12" then acme11 will execute the code. If I use
"-n 2 acme12 acme11", then acme12 will. With three nodes it is identical,
just the first one on the list.
However, I have seen that if I execute the application with another MPI
library, MPICH,
"mpiexec -n 2 acme11 acme12 ./helloWorldMPI"
Everything works as expected. I can use DMTCP with
"dmtcp_launch -h acme11 -p 7779 mpiexec -n 2 acme11 acme12
./helloWorldMPI"
and it succeeds. In this case, it works both with "--ib" and without it.
Just in case it helps, output is below too.
Thansk for your help,
Manuel
