[Math-atlas-devel] 3.7.8

[<rw...@cs...>]

Guys,

I just released 3.7.8, where I get a little faster for double precision on
the Efficeon.  Here's an updated table:

                 PEAK    SSE2          dMM-ic      dMM-oc         dGEMM
                 ====    =========    ===========  ===========    ===========
1.6Ghz Ham64     3200    3051(98%)    2984(93/98%) 2937(92/98%)   2805(88/96%)
2.8Ghz P4E       5600    5178(92%)    4492(80/87%) 4425(79/99%)   4303(77/97%)
1.0Ghz PIII      1000    --------      933(93%)     840(84/90%)    760(76/90%)
1.0Ghz Eff3.7.8  2000    1790(90%)    1595(80/89%) 1371(69/86%)   1280(64/93%)
   "   asymptotic                                                  995(49/72%)
1.0Ghz Eff3.7.7  2000    1790(90%)    1514(76/85%) 1309(65/86%)   1201(60/92%)
   "   asymptotic                                                  970(49/74%)

As you can see, the in-cache numbers are now quite good.  Out-of-cache,
as might be expected on this arch, goes from bad to terrible.
As before, the main problem on this arch is the fact that large problems
to not perform as well as small problems.  For all other archs, the peak
dGEMM number reported above is essentially the same as the asymptotic DGEMM
speed, but for the Efficeon, as you see, it is way under.

Cheers,
Clint
