Ryan:

I´m very grateful for your answer.
You gave a very good perspective to begin my work and make plans for 
future experiments.
Thank you very much.
All the best for you.

Re: [MITgcm-support] Minimal computational requirements to run  MITgcm






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

Dears colleagues: 

I´m a newcomer to this mailing list. 
I´m a researcher in the Climate Change Laboratory in the Vale 
Technological Institute, Belém, Brazil. 
We want to install and run the MITgcm model here to make many experiments 
in several time and space scales using the complete coupled model 
(Oceam-Ice-Atmosphere-Land). 

We look in the manual about the minimal computer requirements to run this 
model, but don´t got any detailed information. 
(Processors or nodes, RAM memory, hard disk capacity, etc). 
Which are the minimal requirements for a low, middle and high running 
performance for that? 

So, if someone can indicate me where I find this information, or could 
give it to us, I will be very grateful. 
Regards.
