Grand Unified Theory of SIMD

Posted by Hemos on from the the-string-theory-of-SIMD dept.

Glen Low writes " All of a sudden, there's going to be an Altivec unit in every pot: the Mac Mini, the Cell processor, the Xbox2. Yet programming for the PowerPC Altivec and Intel MMX/SSE SIMD (single instruction multiple data) units remains the black art of assembly language magicians. The macstl project tries to unify the architectures in a simple C++ template library. It just reached its 0.2 milestone and claims a 3.6x to 16.2x speed-up over hand-coded scalar loops. And of course it's all OSI-approved RPL goodness. "

  1. Autovectorization being add in GCC 4.0 by shawnce · · Score: 5, Interesting

    For those that don't already know is that autovectorization is being worked on for GCC by folks from IBM and others.

    GCC vectorizatoin project (site seem offline atm) but the abstract from a recent GCC summit is up.
