Multi Process Handshaking (MPH) Utility

MPH2: Multiple Components, Single Executable, processors non_overlap

This is a small utility of global handshaking among different component
models. Each component will run on different number of nodes and processors.
The global processor ids don't have to be continuous for each component.
You could get the source code as a tar file here or access the individual
files as follows:

     MPH.outline: brief introduction
     README: this file
     mph.F: MPH_comm module

     master.F: driver for single executable model
     ccm.F: subroutine for atmosphere model
     pop.F: subroutine for ocean model
     cpl.F: subroutine for coupler

     Makefile: makefile.
     processors_map.in: processor ranges for each component model
     script: loadleveler batch script
     output: sample output from interactive run


To compile and run on NERSC IBM SP:
===============================

  1) Type "make", 1 executable will be created: master.

  2) to run interactive job:
     a) unset environment variable "MP_TASKS_PER_NODE"
     b) type in ONE LINE:
        poe master -nodes 6 -procs 9
        -stdoutmode ordered -infolevel 2 > & output &

  3) to run batch job:
     type "llsubmit script".


To compile and run on other machines:
==============================

  Please refer to the corresponding sections of README for MPH1.
