Reported by: balaji Owned by: robl

Component: mpich Keywords:


The LLNL MPI I/O test suite does not seem to pass. The test_sharedpointer() and test_nb_readwrite() routines in the test suite seem to be failing.

Here's some more information - I do not see a problem with sharedpointer, but I did have the test hang. I built the current, updated version (there are errors in the version from LLNL) and ran it like this on my Mac:

mpiexec -n 4 ./testmpio 1 1 

and it ran until here, where it hung:

(0)FLOWTRACE: Leaving test_collective
(0)FLOWTRACE: Entering test_nb_readwrite
(0)Checking nonblocking, independent I/O
(0)Checking Waitall, then Testall
(0)Checking Waitall again
(0)Checking Testany/Testsome before Waitany/Waitsome
(0)Checking Waitany/Waitsome before Testany/Testsome
(0)Checking Waitsome, not all inactive
^C[0]0:Return code = 0, signaled with Interrupt: 2

This problem doesn't happen every time - the next time I ran it, it completed in 6 seconds.
