GPU support for FillBoundary

Open GumpXiaoli opened this issue 6 years ago • 3 comments

In my code, FillBoundary takes most of the run time. I hope to transfer my code to GPU support. Now i am a little worried about the FillBoundary's efficiency. What i want to know is where the fillboundary will perfom. CPU or GPU?

Is it true that your code spends the majority of its time in FillBoundary even within a single node, or is that statement only true at large scale? If so, at what scale does it start to dominate?

In a single node, it usually takes above 35% time since i have optimize the other part.
