Ooooo, good... but FP is a bit of a turn off when compared to Itanium2
numbers (look at the data for the Altix from SGI). I can't beleive
that Intel seems to have done something right for a change :-) The
Altix has a 1 GHz Itanium2 and that gets beaten by this system's
Opteron @ 1.8 at CINT2000, but on CFP2000 the Opteron get horribly
humiliated with its ~ 1100 (base) against the Altix's ~ 1400 (and don't
even look at the newer data for the Altix @ 1.5 GHz). The one thing
that SGI is still doing right is scalability, but that's hardly news.
The scalability of the Opteron machines on the other hand... ouch.
Going from Opteron 144 @ 1.8 to 844 @ 1.8 means a 3.7x change in the
CINT2000 rates... on Windows. Where are the numbers for a 4-way
Opteron on Linux?
How does GCC fare compared to the Intel compiler here?
While I have your attention, does anyone here know of a board _with_ an
AGP slot? NVIDIA has drivers for Linux x86-64 and Linux 2.5 has
agpgart support for AMD's 8151 bridge as well as VIA's K8T400 and SiS'
755, so I guess _someone_ has seen the mythical creature... in the
wild? There's been much speculation regarding the actual availability
of it, and I'd _love_ to get my hands on a 4-way system with at least
one AGP slot, but one with two would be heaven (the kernel supports up
to 8 GARTs but more are just a #define away).
