I’m trying to debug the concurrent kernel on nvvp. My installation is the following:
Ubuntu 14.04 + CUDA 7.0 + Nvidia Driver [375.20] + GTX780
I tried to debug 5 tasks using GPU concurrently because I wanted to verify the behavior when multiple kernels were run at the same time.
These tasks are same code referring by https://github.com/welcheb/CUDA_examples/blob/master/sumArraysOnGPU-timer.cu but process ID is different.
As a result, some kernels appear to be running at the same time like Round-Robin.
I do not use stream.
Does this really work like round robin?
Looking forward to your response.
