This page summarises computer system requirements for using MITgcm in a |
| 14 |
<a href=../online_documents/manual/sarch.html#fig:mitgcm_architecture_goals> |
| 15 |
range of scenarios</a> that spans simulations on a desktop PC to simulations |
| 16 |
run on a high-end supercomputer. The side bar on the left contains |
| 17 |
links to sites from which third party software and hardware, which you |
| 18 |
may require, can be obtained. The text below and the |
| 19 |
<a href=../online_documents/index.html target=mainFrame>online document</a> explain |
| 20 |
in what situations you will need these items. In many cases the software |
| 21 |
you need will already be installed on your computer system and you can |
| 22 |
go straight ahead and <a href=../getting_started/index.html target=mainFrame>start using</a> the model. |
| 23 |
<p><b>MITgcm</b> |
| 24 |
<ul> |
| 25 |
<li> |
| 26 |
runs on a wide <a href=../online_documents/manual/targethw.html>range of computer systems.</a></li> |
| 27 |
|
| 28 |
<li> |
| 29 |
includes special software (called <a href=../online_documents/manual/wrapper.html>WRAPPER</a>) |
| 30 |
to support efficient execution and relatively easy portablity.</li> |
| 31 |
</ul> |
| 32 |
<b>Platforms where MITgcm is run regularly include</b> |
| 33 |
<ul> |
| 34 |
<li> |
| 35 |
PC's ( both Intel and AMD processor based) running Linux.</li> |
| 36 |
|
| 37 |
<li> |
| 38 |
Unix workstations from Sun, SGI, HP, IBM, Compaq.</li> |
| 39 |
|
| 40 |
<li> |
| 41 |
Unix based PC and workstation clusters.</li> |
| 42 |
|
| 43 |
<li> |
| 44 |
high-end symetric multi-processor systems.</li> |
| 45 |
</ul> |
| 46 |
|
| 47 |
<ul>Under the WRAPPER, code also runs very efficiently on high-end vector |
| 48 |
processing systems, if you have one.</ul> |
| 49 |
<b>The minimum you require to run the model is</b> |
| 50 |
<ul> |
| 51 |
<li> |
| 52 |
a computer runing a Unix style operating system.</li> |
| 53 |
|
| 54 |
<li> |
| 55 |
a Fortran 77, Fortran 90 or Fortran 95 compiler.</li> |
| 56 |
|
| 57 |
<li> |
| 58 |
a C compiler.</li> |
| 59 |
</ul> |
| 60 |
<b>To run parallel configurations you also need either</b> |
| 61 |
<ul> |
| 62 |
<li> |
| 63 |
a system that supports multi-threaded programs.</li> |
| 64 |
|
| 65 |
<li> |
| 66 |
a system with an implementation of the MPI library installed.</li> |
| 67 |
</ul> |
| 68 |
|
| 69 |
<ul>Specialized communication software to optimizes performance on a specific |
| 70 |
platform can also be introduced into the WRAPPER.</ul> |
| 71 |
<b></b> |
| 72 |
<p><br><b>Once you have your computer set up</b> |
| 73 |
<blockquote>go here to download the model. The full distribution (including |
| 74 |
examples with input datasets and sample output) is around 50MB. Instructions |
| 75 |
on estimating the computing resource requirements (CPU time, memory usage |
| 76 |
and disk space) for a set of numerical experiments can be found here.</blockquote> |
