I am planning to build a computer for running Comsol, and was hoping to find out how well Comsol can utilize multiple cores for RF Module calculations. The most demanding calculation that we would like to run is calculating the evolution of the electromagnetic field inside a waveguide in 3D.
Does anyone have experience running similar calculations on multiple cores? We are worried that the matrix inversions required cannot easily be split over multiple cores, or that the memory requirements would increase significantly if the job were split over multiple cores. If that is the case, we may be better off purchasing a computer with fewer, faster cores (for example, maybe 8 high-end Xeon cores, 128 GB memory). If parallel computing works well for this problem, we can get more total computing power for cheaper by building a computer with more, slower cores (say 24 mid-range Opteron cores).
Thanks very much for any suggestions!
