Hello everyone, I am currently using freefem++ to complete a 3D numerical simulation experiment, but I found that the 3D code requires a lot of memory to run, otherwise it will report an error. I don’t know how to use parallelization and GPU acceleration yet. Can you recommend me a server with good performance?

If MPI is not used, can the code be run using multiple cores?
