- Subject: array math.h (SSE2?)
Does anyone know of a library, or source file somewhere in which functions from
math.h such as exp() and log() are implemented using SSE2? AMD's libacml_mv
demonstrates that such an implementation can be faster than gcc's, and
furthermore that multiple(2) functions can be computed in parallel on a single
processor. (Making 2-3 fold speed improvements on array calculations).
Or, taking a step back, is there a project analagous to ATLAS or FFTW that
provides fast array computations of these functions on various architectures?
