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 use ubuntu 12.04 64 bits with GTX560Ti.
I install CUDA by following instruction:

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…

I am always confused about static variables, and the way memory allocation happens for them.
For example:
int a = 1;
const int b = 2;
static const int c = 3;
int foo(int &arg){
arg++;
return arg;
}
How is the memory allocated for a,b and c?
What is the difference (in terms of memory)…

Hi,
I have following this blog in setting Xvfb in my ubuntu environment:
http://corpocrat.com/2008/08/19/how-to-install-xvfb-x11-server-in-linux-server/
So I did this:
Xvfb :1 -screen 0 800x600x24&
My question is does Xvfb only allocate memory during initialization? i.e. just enough for a…

I am writing an application and am surprised to see its total memory usage is already too high. I want to profile the dynamic memory usage of my application: How many objects of each kind are there in the heap, and which functions created these objects? Also, how much memory is used by each of the…
