[svn-r2935] Purpose:
Bug fix
Description:
The optimized MPIO code was not working with the TFLOPS machine.
It kept reporting "can't convert from size to size_i" errors in
H5FD_mpio_write() and H5FD_mpio_read().
Solution:
The error was actually in H5S_mpio_spaces_xfer() in H5Smpio.c
in which the variable mpi_count was declared as size_t (only
4 bytes big in TFLOPS) when it should be hsize_t (8 bytes big in TFLOPS).
Corrected and also changed to use the (hsize_t) to case size_i in
H5FD_mpio_write() and H5FD_mpio_read() since that is what it should
be.
Platforms tested:
TFLOPS and modi4 (-64, parallel)
