I am wondering to what extent the above difference can be significant for numerical calculations. ![]() The products have “Pro” and “Max” series with 200 and 400 GB/s bandwidth, respectively. via OpenMP).Įven if compilers do not support M1 natively, is it possible to use “Rosetta” (= Intel emulator) to run any Intel-based compilers on M1 always (including Gfortran and IntelFortran/OneAPI)? In that case, is it okay to assume that I can compile existing program packages (in Fortran/C/C++) and run them in parallel via Rosetta? If this is possible, I think getting a machine with more cores would be useful, but if Rosetta does not support multi-threaded programs (for example), machines with fewer cores may be more reasonable (for cost performance). Also, there are a lot of products with different number of “P/E-cores” (with different prices), but I am not sure whether I can make good use of them in parallel (e.g. ![]() ![]() But I am worried about to what extent it can be used practically for code development, because compilers may be still “experimental” and also I sometimes see user reports about runtime issues. ![]() I have been using a very old Mac (MacMini (2012 model)) for a long time, but because it cannot install newer MacOS anymore (beyond Catalina) + the machine becomes very hot in summer, I am thinking about buying new Mac with M1 chip.
