So we have different threads modifying the thread-local state?

Alberto Ruiz has developed a linear algebra library which could be
seen as an alternative to Matlab/Octave, using the GSL, ATLAS, LAPACK,
etc. IIRC.

I've optimized it in some places, and added an interface which

Thanks, that's very handy!

Hi,
Is there a way to source a file in ghci? I have a series of
initialization commands which I would like to run every time I do a
certain set of experiments, and I've put them in a file. Is it best
just to copy and paste the file into ghci?

Here I'm reading a very large matrix from a file and turning it into a
template Haskell expression. Probably not the most efficient thing to
do, but the error message could be clearer...

Hi Alberto,
I'm experiencing a problem which may be a bug in GHC. Here I take the
dot product of two vectors. I put debugging traces in the 'dotR' C
function (which I call in 'dot'), so one can see the addresses of the
memory blocks. When the vectors are below a certain size, the function
seems
