[Bioclusters] altivec-HMMER bechmark results from Erik Lindahl - 6x faster than dual Athlon

[Dave Waddell]

Don't want to start a processor war but the current Intel chip is a
3.06GHz Pentium 4 not a 1GHz Pentium 3. IMHO, benchmark results should
match current hardware or don't make them at all.

Some nice data from Erik Lindahl at Stanford regarding the new apple=20
altivec enhancements that were added to the hmmer codebase:

Athlon!

program anyway.

released. In the

Benchmark data from Erik is enclosed in PDF form.

BioTeam has built a double-clickable Mac OS X package installer for this

code but I've been a slacker and have yet to put it on our website.=20
Interested parties should email me directly if they want the package=20
version of these binaries.
