Hello, Rob, and Open MPI users,
Thank you for your advice.
I understand that current Open MPI 1.5.3 Win-32bit binary distributed
from this site
don't support MPI-IO on NTFS.
I try to check this problem with using other code.
The code is the following code:
First I insert the following lines after "MPI_Init( &argc, &argv );" line.
m = 20;
n = 30;
Of course, the name of output file is ... "/pfs/datafile"-->"datafile".
It correctly works on Open MPI 1.4.1 on Linux Ubunts 10.04 LTS. I
found "datafile" after run.
However, It doesn't work correctly on Open MPI 1.5.3 32bit binary,
Windows 7 32bit SP1.
I can't find "datafile"
