[MITgcm-support] Minimal computational requirements to run MITgcm

[Ryan Abernathey]

Luis,

I don't know if anyone has gotten back to you about this... Here is a  
response from my limited knowledge.

MITgcm is a very flexible model. It can run on almost any hardware.  
Some users run it on the most powerful supercomputers in the world  
using thousands of nodes, and generating terabytes of data. On the  
other side, I would not be surprised if someone has it running on  
their mobile phone. You can find a de-facto list of the supported  
platforms in the tools/build_options/ folder.

There are no "minimal requirements" in general. The requirements are  
determined by the scale of your problem. The speed of execution will  
depend on your hardware. For long, complex, high-resolution  
simulations, the only efficient way to run the model is in a parallel  
environment such as on a cluster using MPI.

A good way to get started is to compile some of the basic tutorials on  
your personal computer to get a feel for how it works and how fast it  
runs.

Hope this helps,

Ryan
