With COMSOL, there is a relationship between the best effciciency of cores to the number of memory channels and the figure is 2 cores per memory channel. CPU Cores: Again, my knowledge is limited, but when I lent a system to a friend for some vonKarman turbulence simulations to be run on Matlab, we talked a awhile about the efficiency of parallelization in simulation software. Perhaps the 128GB of RAM in your preliminary specification has been dervived from experience, but it may be wise to increase the quantity to prevent saturation.Ģ. The technique to determine quantity is to run small models and monitor the memory used and the degrees of freedom from these smaller models. ![]() Memory: Simulation in general is very memory intensive and COMSOL projects apparently can quickly saturate the RAM, so both quantity and speed are important considerations. I don't have experience with either COMSOL nor CST, but I've talked hardware a bit at my friendly neighborhood linear accelerator and within my second-hand limited knowledge of COMSOLand CST, there are a couple of parameters and quasi-equations that might act as l guidelines:ġ. ![]() I hope other more informed than I will comment.
