OpenCL is definitely the way to go for a cross platform solution with
both nvidia and AMD having released beta runtimes to their respective
developer networks (free as in beer subscription required for the beta
dowload pages). Final public releases to be expected around 2009 Q3.

this is a message mostly for those attending the conference who know

With OpenCL implementations making their way into the wild, that's probably
a better target than CUDA.

But you can "cheat" and put them on one line (if that's all you're after):
>>> x = np.array([1, 2, 3])
>>> maxi = x.argmax(); maxv = x[maxi]
>>> maxi, maxv
(2, 3)

Although I've used Matlab for many years and am quite new to Python, I'm
already convinced that the Python/NumPy combination is more powerful and
flexible than the Matlab base, and that it generally takes less Python code
to get the same job done. There is, however, at least one thing that is much

I'll help, if you want. I'm good with GPUs, and I'd appreciate the

So far, no one's proposed a BoF I wouldn't be interested in attending. :-)
(except for fact that at least some will have to overlap, yes? :-( ).

Hi All,
At the present time David C. and myself are doing most of the work in the
numpy c code base. I am wondering if there are more people out there who
might want to get involved in that end of things and if there are ways we
can help them get started. If folks are interested we could have a BO

OK. I contacted several attendees who are not on the numpy list, and
it looks like we've got six or seven people interested.
I've never been to the conference or organized a session like this.
Any guidance?

Hi everyone,
I was wondering if you had any plan to incorporate some GPU support to numpy, or
perhaps as a separate module. What I have in mind is something that would mimick
the syntax of numpy arrays, with a new dtype (gpufloat), like this:
from gpunumpy import *
x=zeros(100,dtype='gpufloat') #
I already replied to OP, but I'll say publically:
"+1", as long as it's not at the same time as the as-yet-potential BoF on "the
Future of SciPy".
