Still, I assume nVidia, etc, might eventually develop a work around that would make CUDA more beneficial. I know Ansys is starting to take advantage of GPU's, but COMSOL has said the mount of RAM on current GPUs is not enough to support their solvers. Many such boards have significant GPU capabilities. If I build my own instead of buying from Dell or HP, I will probably get an dual processor capable board so I can add on in the future. As such, I am paying attention to number of processor cores, higher cache RAM, and faster system bus. Since I don't think I can afford a cluster or US $9,000.00 dollar workstation computer with dual processors, I really need to try and optimize my system. Some research has seemed to indicate Intel is a better performer as well. I was reviewing some processors today, looking at the benchmarks, and it seems that Intel has better performance than AMD. Since I am learning, I thought I would make sure before I concentrate on such processors as Intel Xenon. Question: When thinking about multiple core processors, will Elmer Multi-physics take advantage of processor multitasking? I assume it will since you mentioned MPI. I am willing to spend some money in this endeavor. I am asking because I want to build an effective computer for doing multi-physics modeling. The numbers are often measured in GigaTransfers/second (GT/s) and can be found on manufacturers' webpages (see example below).Īs high memory bandwidth as possible is beneficial." The number of CPU memory channels should be as high as possible.Ī CPU with as fast a memory bus as possible is beneficial. "A 64-bit operating system is highly recommended.įor a given hardware, the choice between Windows, Linux, or Mac OS X will not significantly affect performance.Īt least 4-8 GB physical RAM per core of the computer is recommended.ĭual-socket or if possible four-socket nodes are recommended. What do you think about these suggestions, and can you add anything to them? I do not mention COMSOL for advertisement reasons, but mention COMSOL because I obtained the info from their website. I came across a COMSOL page that made the following recommendations. I suspected the requirements would be similar to gaming computers. Also, I had the same question and was searching today.
