Cuda Driver Api Vs Runtime Api

The C++ source code concisely recreates the simplePBO example from Part 15 of this article series using C++ classes. http://cuda-programming.blogspot.com/2013/01/what-is-cuda-driver-api-and-cuda.html The runtime API is easier to use, but the driver API gives you more control over low level details. Cuda Runtime Api Here the context is lazily initiated by the cudaSetDevice call (note I incorrectly asserted that cudaSetDevice doesn't establish a context, but at least in CUDA 5 it appears to. Culaunchkernel Example My one year old and her mother are moving in with a man I've never met Why is the heart not in the middle of the body?

Ask Question up vote 2 down vote favorite I have a GUI application with a producer thread and an OpenGL thread, the OpenGL thread needs to call CUDA functions and the check over here While generally subefficient on large sequences compared to algorithms with better asymptotic algorithmic complexity (i.e. This sample requires devices with compute capability 3.5 or higher.
