[svn-r15045] Bug fix.
Description: perf would crash at the end as it complained it was doing MPI calls after MPI_Finalize() is called. I suspect the HDF5 library is making MPI calls in the at_exit area. This should not happened. Solution: Added the H5exit() right before MPI_Finalize() fixed the problem. But it needs to find out why HDF5 library is making MPI calls in the at_exit() area. It should not. Also, changed the temporay data file name from /tmp/test.out to perftest.out, both to avoid multiple instance of this may use the same /tmp/xxx name and also make the file name less generic. Tested: Kagiso PP.
