MITgcm -

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

-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 symetric -multi-processor systems.

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 -

-a computer runing a Unix -style operating system.
-a Fortran 77, Fortran 90 or Fortran 95 compiler.
-a C -compiler.

-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

+
+an automatic +differentiation tool.

An example experiment illustrating the automatic differentiation process +can be found here.
