I heard that Intel has a document with
examples of "multiple accumulator" programming
for the PPro. One example is supposedly
like saxpy() or daxpy(), and ostensibly
the speedup for the multi-accumulator
approach was something like 150 MFLOPs
vs. 60 MFLOPs.
Has anyone seen this example... and could you
tell me where I might get the document? I've
see Terje Mathisen's excellent sqrt2(1/x)
example, and am looking to increase my bag
of tricks...
