Hi, Does GPU speed exponentially drop as number of threads increase beyond a certain number?. I used to allocate number of threads= number of transactions in data under consideration. For Tesla K80 I see exponential drop in speed above 30290 Threads. If true, is it a best practice to keep number of threads low and iterate over the data to get results at optimum speed. How to find best number of threads for a GPU?
Thanks Aseem
