Here are a couple of links you might find helpful:

1) http://developer.apple.com/hardware/ve/vector_libraries.html
2) http://hpc.sourceforge.net/
3) http://developer.apple.com/hardware/ve/index.html

#1 introduces the Apple vector/matrix libraries which are altivec accelerated
#2 has a reference to macstl which has accelerated numerics classes for C++
#3 is the Velocity Engine / Altivec homepage

good luck!
