-Downloading Release 1.0-b1 of MITgcmUV with CVS

- -

Environment

- -

setenv CVSROOT :pserver:cvsanon@mitgcm.org:/u/u0/gcmpack
-cvs login ( CVS password: cvsanon )

-You only need to do "cvs login" once but the environment should be set -in you .cshrc or .tcshrc. -

-To obtain the release (with CVS information)

- -

cvs co -d MITgcm-r1b1 -r release1_beta1 -P MITgcm

-This creates a directory called MITgcm-r10b1 in which you'll find -the source code. -

For later on, CVS will allow you to upgrade your copy of the code as -patches are released. For more information on how to use CVS try this -starting -page. -

+Hardware/software requirements

+This page summarizes computer system requirements for using MITgcm in a +range +of computers from desktop PC to simulations run on a high-end supercomputer. +

The side bar on the left contains links to sites from which third party +software and hardware, which you may require, can be obtained. +

The text below and the online +document explains when you will need these items. In many cases the +software will already be installed on your computer and you can go straight +ahead and start +using the model. +

MITgcm +

+runs on a wide range +of computer systems.
+includes special software (called WRAPPER) +to support efficient execution and relatively easy portability.

+Platforms where MITgcm is run regularly include: +

+Unix +PC's (both Intel and AMD processor based) running Linux.
+Unix +workstations from Sun, SGI, HP, IBM, Compaq.
+Unix based PC and workstation clusters.
+high-end symmetric +multi-processor systems.

+ +

Under the WRAPPER, code can also run very efficiently on high-end vector +processing systems. +The minimum you require to run the model is +

+a computer running a Unix +style operating system.
+a Fortran 77, Fortran 90 or Fortran 95 compiler.
+a C +compiler.

+To run parallel configurations you need +

+a multi-process computer

+a compiler +and that supports multi-threaded programs.
+a system with an implementation of the MPI +library installed.

Instructions on running multi-process codes can be found +here. +
Instructions regarding muti-threaded execution can be found +here. +

Specialized communication software, to optimize performance on a specific +platform, can also be introduced into the WRAPPER. This process is discussed +here. +

Before running a parallel code we recommend you try one of the basic +examples described on the +getting started +page.

+To perform derivative calculations you need +

+an automatic +differentiation tool.

here

+ +

Once you have your computer set up +

go here +to find out how to download the model. The full distribution (including +examples with input datasets and sample output) is around 50MB. Instructions +on estimating the computing resource requirements (CPU time, memory usage +and disk space) for a set of numerical experiments can be found here.

+Simulation output is usually examined +

using one of several standard +analysis tools, depending on individual preference and experience.

+ +

Still confused? +

send us mail. We like +our software to be used and are happy to help out if we can. +
