Just for fun, I run bench.m on my Barton
System:
Barton @ 1.4GHz (reason: my memory is PC2100, so Barton downspeed :-( )
DDR ram 512MB
GF 4 MX440.
Matlab 6.1
Win2k pro.
LU decomp: 0.51s
Then I replace the ATLAS library with the one claimed to be optimized for
AthlonXP
(see here: http://www.econ.ucsd.edu/~ksheppar/matlab/MatlabAtlas.htm)
However, there is NO speedup observed, LU costs even 0.71s!!!
So I switch back to default ATLAS)
I am also curious that if any existent package can use SSE2's a
