Hi,
I have encountered some run time errors in the general purpose program given
below. Could you please assist me in correcting this.
The MPI code is written in Fortran 90. The concept of subroutine is used
because I want to write program for another scientific problem.

It would help if you would include the error messages you encounter.
You need to call MPI_Init(ierr) before you can call (just about) any
other MPI call. E.g., add "call MPI_Init(ierr)" as the first executable
statement of your "program prog".
The error I get with your program is

Arun,
Before you call any MPI subroutines, you have to call MPI_Init(ierr) first.
Once you put that line in, it should work.
Cheers,
Ethan

First of all, the reason that I have created a CPU-friendly version of
MPI_Barrier is that my program is asymmetric (so some of the nodes can
easily have to wait for several hours) and that it is I/O bound. My program
uses MPI mainly to synchronize I/O and to share some counters between the
nodes,
