Does anyone have any recommendations of a good FORTRAN compiler for a DECstation 5000? We currently have the f77 supplied by DEC, which is not `good'. My main use is a 3-D finite difference model. When run on a Silicon Graphics Personal Iris with the same MIPS CPU running at 20MHz instead of 25MHz the code still runs 30% faster than the best I can get from the compiler DEC sells when running on the 5000. Using a test 400x400 matrix multiply the C compiler generates code which runs 3 times faster than the code f77 generates. (They both have the optimum loop ordering for the respective languages) kevin
