Hi LMHmedchem,

I attach here 5 files-
restart_20080515-001.txt,.........restart_20080515-004.txt and restart_20080515.txt which is the result of hcat.exe working on the first 4 files. The actual names of these files should be without the extension of .txt, but I added it just for the ease of uploading them here.
This is a case where the executable hcat.exe of the program swanhcat.ftn was successful in combining the 4 files restart_20080515-00(1...4) to generate restart_20080515. In this case I have run my model with 4 processors to generate the 4 files restart_20080515-00(1..4). When I work with more processors, more such files will be generated. The program swanhcat.ftn (serial program) fails to combine the files when the file numbers are large or may be when the total size of all the files exceeds some value.
Even I can see that the program should be able to handle 1000 files, which is much above any practical requirement.
I tried running the program in HPC(High performance computing), which is having 128GB RAM per node. I was given unlimited memory access to run the program, but it failed. I also tried in my PC with 12 GB RAM, still it failed.

Making FORTRAN code more efficient

Hi, I have a very large, very old FORTRAN code that I work with. The code is quite messy and I was wondering if I can speed up execution time by finding subroutines that code execution spends the most time in. Is there any kind of software I can use to see where the code spends most of the...

MPI_Error_string(3)						      LAM/MPI						       MPI_Error_string(3)

NAME

       MPI_Error_string -  Return a string for a given error code

SYNOPSIS

       #include <mpi.h>
       int MPI_Error_string(int errcode, char *msg,
	      int *plen)

INPUT PARAMETERS

       errcode
	      - Error code returned by an MPI routine or an MPI error class

OUTPUT PARAMETER

       msg    - Text that corresponds to the errorcode
       plen   - Length of string

NOTES

       Error  codes  are the values return by MPI routines (in C) or in the ierr argument (in Fortran).  These can be converted into error classes
       with the routine MPI_Error_class
	.

       These messages are provided in English (En_US - English/United States).	If there is an interest in providing messages  in  different  lan-
       guages, please submit requests to the LAM mailing list (see http://www.lam-mpi.org/contact.php ).

NOTES FOR FORTRAN

       All  MPI  routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the end of the argument list.  ierr
       is an integer and has the same meaning as the return value of the routine in C.	In Fortran, MPI routines are subroutines, and are  invoked
       with the call statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.

MORE INFORMATION

       For  more  information,	please	see the official MPI Forum web site, which contains the text of both the MPI-1 and MPI-2 standards.  These
       documents contain detailed information about each MPI function (most of which is not duplicated in these man pages).

ACKNOWLEDGEMENTS

       The LAM Team would like the thank the MPICH Team for the handy program to generate man pages ("doctext" from ftp://ftp.mcs.anl.gov/pub/sow-
       ing/sowing.tar.gz ), the initial formatting, and some initial text for most of the MPI-1 man pages.
