BLAS may well be the most tested, optimized and benchmarked code in the world. 
It is highly unlikely that anything will be faster on hardwhere anyone is 
likely to run across. Given that the vast bulk of super computer time is 
spent on matrix math, it should be fair to say that BLAS is probably the 
most executed code on the planet.
