CUDA and PyCUDA

Does anyone here use CUDA for scientific computing? I need pointers to any good tutorials and sample code that anyone knows about. Also, I'm really interested in working with PyCUDA and coding in Python instead of C/C++. I need this code to be cross platform without alot of trouble and I'm leaning to wxPython as a possible GUI (I'm developing an app that must be usable by people that don't even know what Python or CUDA or even C are).:cool:

Re: CUDA and PyCUDA

I do not know about the pyCUDA API. But I have been using CUDA. The best way to start is to use the CUDA programming manual http://developer.download.nvidia.com/co … de_1.1.pdf

The 2.0 manual is in beta... So I guess you can read that as well. For running CUDA based programs, you need a fairly new GPU like geforce 8x or the newer teslas. CUDA programs are sadly not too portable because it depends on the graphics card which limits the number of grids of threads.  Also, you have to be very strong in C. CUDA is just a big extension of C for data parallel SIMD computing. Dust out your old parallel computer architecture books and enjoy!
