Thanks for all the recommendations. It seems that the version 2.1 compiler from MIPS, also sold as the version 2 compiler from DEC, is the best there is right now. Unfortunately it is what we have and I am still not happy with it. There was a comment that there is a hyper optimizer being used at Rice. If anyone has any specifics on this I would appreciate comments. The only explanation for the SGI running faster was that memory caching was implemented in a manner which the compiler was better able to take advantage of. At least this was the only explanation postulated which I was unable to rule out. The real result though, is that if one wants speedy code on the DEC 5000, one should program in C, not FORTRAN. I will concetrate on running my long FORTRAN codes on a CRAY YMP. Kevin Knappmiller Department of Mechanical Engineering Colorado State University Fort Collins, CO 80523
