23  <br>&nbsp;  <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&nbsp;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>

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>
