MPH1 and MPH2: Multi-Component Multi-Executable or Multi-Component Single Execut able

MPH2a: 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.
