Multi Process Handshaking (MPH) Utility

MPH2b: Multiple Components, Single Executable, processors overlap, flexible

Global handshaking among different component models. Each component will
run on a set of nodes (processors). Processors in different sets are
determined in "processors_map.in" file. They could overlap. Different
components could be sequentially called. Most flexible.

You could get the source code as a tar file or access the individual
files as follows:

     MPH.outline: brief introduction
     MPH2b.design: extra explanation
     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 5 -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.
