[MITgcm-support] Workstation advice for MITgcm passive tracer runs

[QI Yuanzhi]

Dear MITgcm community,

My name is Yuanzhi Qi. I am planning to use MITgcm to simulate the distribution and transport of radioactive tracers in the ocean. Specifically, I aim to model the historical concentration changes of Iodine-129 (I-129) in the Arctic Ocean over the past 80 years. This work is intended to serve as a foundation for future global-scale I-129 simulations and, potentially, for using I-129 as a tracer to study the broader marine iodine cycle.

My main question is: Is it feasible to run such 3D simulations on a single workstation? If so, could you provide specific hardware recommendations—such as CPU, GPU, RAM, and storage?

For instance, should I consider a CPU with 16 cores, 32 cores, or more? Would 128 GB of RAM be sufficient, or would I need 256 GB or more?

Additionally, if there are any example setups or configurations for similar oceanic passive tracer studies beyond the User Manual, I would be very grateful for any references or pointers.

Thank you in advance for your guidance.

Best regards,

Yuanzhi
