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

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 here 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.
