Free all allocated memory on the device? Is there a way to free all the memory I allocated during a

Is there a Cuda function to Free all the memory on the device I allocated during my program?

Of cause I am very cautious to free every unused resources right ahead but during development its easy to miss to free some pointers.

As far as I know there is no such function. You need to take care of your memory allocation.

cudaDeviceReset() should do it.

cudaDeviceReset is specific to the context, right?

5

This function will destroy all the resources. I think that mapped PBOs will also be destroyed.

Thanks for your answers.

cudaThreadExit()

Explicitly cleans up all runtime-related resources associated with the calling host thread. Any subsequent API call reinitializes the runtime. cudaThreadExit() is implicitly called on host thread exit

If I want to free some previously allocated memory instantly in the running process , how would I do that? I have used malloc and mallocpitch .

if you used cudaMalloc or cudaMallocPitch, you would use cudaFree to free those specific resources.

Thanks for reply, I have used that in my code but my question is, is it going to execute, i.e., instantly free memory during running process.
