Comment (by SevenThunders):
Replying to [comment:2 igloo]:
I thought I had replied to this, but I will do so again.
Here is what I get using my binary atlas cblas
{{{
"rounded base = 0"
C[0] = -1.#IND
C[1] = 2
C[2] = 2
C[3] = -1.#IND
}}}
This is on my AMD athlon x2 processor running windows xp 64 (the library
is still 32 bit).
I get similar results running it on an Intel core duo processor with a
different atlas compiled blas.
Both blas's were compiled with threads turned on so in theory they are
multi-threaded if that makes any difference.
One question I have is does the code works correctly on your box if you
compile it using the older ghc, but with my supplied atlas.dll binary, say
ghc 6.6.1? On my box it runs just fine with the older ghc.
