I would like to take a chance and re-submit the request for any information on fast, reliable FORTRAN compilers that will run under UNIX. It is my understanding that one of the main problems contributing to poor execution times is the nature of the floating point library -- ie: all floating point is double precision. Perhaps someone on the net knows of a replacement library available that has been optimized? Please note, I am NOT looking for more UNIX vs. VMS benchmarks. MDI is committed to UNIX as an operating system, and I must find an appropriate solution. Gary W. Kenward, Mobile Data International Inc. Riverview Industrial Park Richmond, B.C. V7A 4Z3 SNAP!

I'm not sure about the "all floating point is double precision" part (not having worked on any of that myself), but slow library routines are indeed one of the reasons for slow execution of Fortran routines on 4.2BSD Vaxen. There is a "native" math library available (-lnm) which you can use if you dare (it is at least somewhat more buggy than the conventional Fortran math library, I believe). 4.3BSD has a revised native math library for Vaxen, I hear. -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 454 4251) UUCP: seismo!umcp-cs!chris CSNet: chris@umcp-cs ARPA: chris@maryland
