I will not get into the language comparison or benchmarking aspects of this thread. I just note that "linking the f90 library that contains matmul" isn't necessarily that straightforward. Matmul is an intrinsic. It is not at all given that there even *IS* a library that contains it; a compiler is quite free to always do it inline. And even if much of the work is in a library routine, the interface to them isn't necessarily known outside of the compiler. Intrinsics are basically part of the compiler internals. They *MAY* be implemented with callable library routines, but there is no guarantee of that. And it certainly isn't a portable way to call them. -- Richard Maine maine@qnet.com
