Hello,

I'm using PVM coupled with PIOUS for parallel I/O for some non STDIO to 
enable concurrency.
The problem is whenever I tried to create a "file descriptor" for reading a file,
it gives an error message like the following:

To create a file descriptor, I used the system call:
   if ((parameter_fd=pious_open(parameter_fname,
                                PIOUS_RDONLY|PIOUS_NOCREAT,
                                PIOUS_IRGRP)) < 0){
 
The error code (the value returned) that I've got: PIOUS_ENOENT


Creating a fd of a file for WRITING is OK, but not for READING a file somehow.
I think I've set up all other things correctly  because they worked for all other
environment.

Anybody has an idea about what's wrong with this?
Thank you for your attention.
