When writing CUDA applications, you can either work at the driver level or at the runtime level as illustrated on this image (The libraries are CUFFT and CUBLAS for advanced math):
I assume the tradeoff between the two are increased performance for the low-evel API but at the cost of increased…

I have a VS2010 project that was tested with CUDA 4.0, today I installed CUDA 4.2 and I want to update this project, the problem is that when I try to run the project it asks me for cudart32_40_17.dll, but since this is CUDA 4.2 I only have on my folders (C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v4…

I'm currently using CUDA.NET library by GASS.
I need to initialize cuda arrays (actually cublas vectors, but it doesn't matters) in one CPU thread and use them in other CPU thread. But CUDA context which holding all initialized arrays and loaded functions, can be attached to only one CPU thread.
There…

So I downloaded the ATI Stream SDK. I don't have a gpu now so I use the '-device cpu' and got the programs/examples in the OpenCl directory working by adding the directory to LD_LIBRARY_PATH etc.
Now the problem is when installing QtOpenCl.
configure script gives me:
skkard@skkard-desktop:~/Applications/qt-labs-opencl$…

I've been playing with OpenCL recently, and I'm able to write simple kernels that use only global memory. Now I'd like to start using local memory, but I can't seem to figure out how to use get_local_size() and get_local_id() to compute one "chunk" of output at a time.
For example, let's say I wanted…

I am trying to parallel a classic map-reduce problem (which can parallel well with MPI) with OpenCL, namely, the AMD implementation. But the result bothers me.
Let me brief about the problem first. There are two type of data that flow into the system: the feature set (30 parameters for each) and…

Is it possible to use custom types in OpenCL kernel like gmp types (mpz_t, mpq_t, …) ?
To have something like that (this kernel doesn't build just because of #include <gmp.h>) :
#include <gmp.h>
__kernel square(
__global mpz_t* input,
__global mpz_t number,
__global int* output…
