thanks for your reply. But checkpointing the first process started by
mpirun did not solve my problems.
Today I also tried checkpointing with LAM/MPI 7.0.6 without success. But
LAM/MPI 7.0.6 behaves different. In LAM/MPI 7.1.1 a single checkpoint
file with the context of mpirun but without the context of the
application was saved. No errormessages were displayed. With LAM/MPI 7.0.6
no checkpoint file at all was written, but in the console where mpirun runs
the error message "rploadgov failed." was displayed.
Another difference in the behaviour of LAM/MPI 7.1.1 and 7.0.6 is that
unter 7.0.6 mpirun is listed three times in the process table, while
unter 7.1.1 mpirun occurs only once. I don't know, if this is a bug or a
feature.
If anybody has done checkpointing with LAM/MPI and BLCR successfully, I
would like to know his exact configuration.
