Dear all, Hello, I am running a batch scattering radiation simulation program on a multi-core processor. It involves the simulation of multiple profiles on multiple frequency grids. And the scattering data I use is the ARTS single scattering database. However, it is found that the role of multi-core processors cannot be fully realized. Even though I choose multiple cores by running the command "-n", the actual operation only use a few cores. I'm sure that the ARTS I compiled supported OpenMP. I guess maybe my program is not efficient enough.
I would like to ask how to make calculations more efficient through reasonable settings when writing programs. For example, loop multiple profiles for a single frequency point, or calculate multiple frequency grids for a single profile, or other more reasonable ways. Looking forward to your replies and suggestions. Best Regards, Song shuhua
