-MITgcm has been designed to run efficiently on a wide range of computer
-platforms. This is made possible by its WRAPPER interface which
-largely insulates the 'under the hood stuff' from the user.
-
MITgcm also runs on a single PC and PC clusters.
-
The minimum you require to run the model is a PC running linux and a
-FORTRAN compiler.

Once you have your computer set up, go here to download the model.

+Hardware/software requirements
+This page summarises computer system requirements for using MITgcm in a
+range
+of scenarios that spans simulations on a 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 explain in what situations you will need these items.
+In many cases the software you need will already be installed on your computer
+system and you can go straight ahead and start
+using the model.

+
+Platforms where MITgcm is run regularly include
+
+
+Under the WRAPPER, code can also run very efficiently on high-end vector
+processing systems, but we can't afford one.
+The minimum you require to run the model is
+
+To run parallel configurations you need
+
+-
+a multi-process computer
+
+
and either of
+-
+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
+
+To perform derivative calculations you need
+
+
+
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 experiemnce.
