MKL seems to beat ATLAS, but some problems... (was RE: linkin g R against MKL)
...owing comparison.
For n=1000, 10000, and 100000, x is matrix(runif(n*100), n, 100). y is
runif(n). I compared the timing for crossprod(x,x), qr(x), and lm(y ~ x).
Reported below are results of system.time()[1]:
n x'x qr(x) lm(y ~ x)
ATLAS321 1000 0.04 0.18 0.75
MKL51 1000 0.03 0.12 0.72
ATLAS321 10000 0.37 2.83 6.12
MKL51 10000 0.28 2.77 6.08
ATLAS321 1e+05 3.76 33.48 53.7
MKL51 1e+05 2.76 27.23 47.26
So it does seem to provide some modest improvement over ATLAS, at least on
this particular machine (dual P3-...
