What will be the influence on Blitz++ of the new sets of vector
processing instructions that will be soon avalaible for Pentium (Katmai)
and PowerPC (Altivec) ? Basically, the processor will be able in one
cycle to add, substract, ... 128 Bits vectors (both for integer and
floating-point on Altivec) : this means 16 double or 32 float or integer
-> this would be an implementation of choice for the classes TinyVector
and like.
