Suppose I have an active CUDA context associated with device i, and I now call cudaSetDevice(i). What happens? : Nothing? Primary context replaces the top of the stack? Primary context is pushed o...

I thought I had the grasp of this but apparently I do not:) I need to perform parallel H.264 stream encoding with NVENC from frames that are not in any of the formats accepted by the encoder so I h...

This question is a followup on Jason R's comment to Robert Crovellas answer on this original question ("Multiple CUDA contexts for one device - any sense?"): When you say that multiple contexts ...

I have a working app which uses Cuda / C++, but sometimes, because of memory leaks, throws exception. I need to be able to reset the GPU on live, my app is a server so it has to stay available. I ...

Can anyone please explain or refer me some good source about what is a CUDA context? I searched CUDA developer guide and I was not satisfied with it. Any explanation or help will be great.

How can I create a CUDA context? The first call of CUDA is slow and I want to create the context before I launch my kernel.

I want to understand how a cuda context is created and associated with a kernel in cuda runtime API applications? I know it is done under the hood by driver APIs. But I would like to understand th...

I am using an application presently that spawns a bunch of pthreads (linux), and each of those creates it's own CUDA context. (using cuda 3.2 right now). The problem I am having is that it seems ...

I'd like to pass a Cuda context between two independent Linux processes (using POSIX message queues, which I already have set up). Using cuCtxPopCurrent() and cuCtxPushCurrent(), I can get the con...
