> Introducing thread parallelism at a compute kernel level Conceptually this is not a small change. Personally I think parallelizing on the datafusion level and keeping kernels single-threaded is the better model. The benchmark is now also testing a much larger array (2^20 elements) than what is usually used as a chunk size, so in reality the speedup due to parallelism would be much smaller. I'm totally fine with a small slowdown if that leads to cleaner and safer code. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
