I don't think so. The jump from 46 threads to using 46 real cores is massive. The jump from 46 real cores to 92 threads is < 30 elo.CMCanavessi wrote: ↑Sat Sep 15, 2018 11:52 pmJust to clarify, ponder will be off and thread count for each engine will double, right? Otherwise it makes little sense.chessdev wrote: ↑Sat Sep 15, 2018 10:49 pm Hello all. Update time. After extensive discussions, we have decided to turn Ponder OFF at this time (for Stage 2). We recognize that there are some irregularities with how threads are being allocated in some engines and situations, and until we figure that out, we are going to play it safe.
That said, we believe the games have been incredibly entertaining, and the outcome is more or less expected, which leads us to believe that this was not a meaningful issue in the scheme of things. But we do want to find solutions going forward. We are looking at options for things we can do on our end to ensure that each engine gets the processing power it deserves. That may mean that Ponder will be turned back ON for Stage 3. We will see.
Additionally, we will also be providing the Arena logs for Stage 2 and beyond. Links will be provided when Stage 2 begins. As for Stage 1 logs, some have been already provided, and we may reconsider releasing all of Stage 1 in the future. Right now we need to be fully focused on the rest of the event.
Thank you all again for your insights and patience!
That jump assumes that all engines have NUMA support. It is my understanding that only Stockfish, Houdini, Texel, and Ethereal have such support. I'm tempted to add Komodo into that too, based on some chats with Mark, but I don't know that first hand.
