[svn-r3926] Description:
Changed MPI_File_seek then MPI_File_write or MPI_File_read to just
MPI_File_write_at and MPI_File_read_at. Some compiler, e.g., IBM
mpcc_r does not support MPI_File_seek and MPI_File_read or MPI_File_write.
This is a better measurement against HDF5 performance since HDF5
uses MPI_File_write_at and MPI_File_read_at all the times.
It is a more thread safe to use MPI_xxx_at than the other seek then
read/write approaches.
Platforms tested:
modi4 (irix64 parallel), IBM sp2.
