Dear Tench: Profilers do not compile code. Compilers compile code. I thought that any one with a small amount of education would see the difference in usage and correctly realize that I referred to the Intel Compiler (both the C/C++ and Fortran compilers of Intel have been given the name (nickname?) of Vtune in these discussions). BTW, someone (Tim Wilkins IIRC) compared the performance of DGEMM in the SPEC 2K suite to an Atlas optimized library using version. The Atlas one got nearly 10 times the performance of the one used in SPEC on the same data. Atlas appears to be heavily used in the target market of SPEC benchmarks, workstations doing scientific and engineering number crunching. It shows that a truly high optimizing compiler (far beyond any available today (look at the trouble Intel, SGI, and HP have in making good IA-64 compilers and that is optimizing a simpler CPU architecture)) could increase the performance of many applications. It currently requires a good application design and optimizing team to generate a high performance application. Pete
