I am pleased to announce the release of ATLAS 3.6.0, the new ATLAS stable.
It's been two years since the last stable, so there have been a large number
of changes. I will provide a few highlights here, and you can examine the
ChangeLog for full details (the ChangeLog can be found on SourceFourge
download page or in ATLAS/doc/ChangeLog).
The first thing is, of course, speedups. ATLAS 3.6 is *much* faster than 3.4
for most common architectures. In particular, Opteron, Athlon-64, Itanium 2,
Pentium 4, Pentium 3, UltraSparc II/III are all signficantly faster in 3.6
than they were under 3.4. To give a flavor of this speedup, I have posted
a few initial timings at:
ATLAS also supports arch defaults for several new architectures. In addition
to the machines mentioned above, ATLAS has defaults for IBM Power 4, and
you can also build ATLAS using Intel's compiler on most Intel platforms.
Another new feature in 3.6 is an improved SYRK/HERK implementation, with
associated Cholesky speedup.
