Various people have started looking into this, but so far no one has produced code. One big issue (at least for me) with pycuda is the requirement for boost, but I am not sure how that could be overcome. Since I am personally only interested in the CUDA BLAS the suggested way to hook it into Sage was directly via Cython, but recreating pycuda via Cython seems like a large waste of effort and should be avoided at all costs. The main issue with boost I see is that PolyBoRi ships with a subset of boost and installs it into $SAGE_LOCAL/include/boost. I assume that it will not be enough of boost, i.e. boost python is not part of it. Since PolyBoRi also has an interface to Python using boost Python we might be able to add the bits needed to the polybori.spkg, otherwise I see potentially huge trouble by colliding boost versions in the tree. And shipping boost itself is not really an option due to its rather large size. > (I think cuda-python) can do this.

I think using numpy arrays here for now might be the way to go, but that limits you to numpy data types. Since we are talking about numerical computations it seems that we will not lose functionality here at all. > Of course this work would > be shared with the community.

There are various people waiting to but the next generation of Tesla hardware, i.e. the one that actually provides IEEE doubles. I am basically waiting for it to become available since the things I am interested in do require IEEE precision and close to IEEE is not enough. > Any advice and pointers most welcome. Please keep us up to date how things are going and let us know about any problems you have. This is an area we should definitely make some progress this year. > Regards, > > Simon Cheers, Michael --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
