Chessify 1 BN/S server

Nice speed. With 10x speed You solve test positions 10x faster and get +10 ELO (max) in games .

Is that what SF test results show these days?

That's quite a bit lower than I expected (I assumed 10 elo per speed doubling, so 30-40 elo here).

Presumably the cause isn't an SMP search issue with SF, but just chess as a game running out of headroom and slower SF can hold the draw too often?

As a side note, the cluster branch can scale to much higher number of threads. Chessify looks genuine.

Is there an instruction guide to getting the cluster setup?

You have a cluster!?

I have a bunch of workstations from the office, a router and a large switch. So, yeah, the ingredients are there to make the cake I think.

There is something at https://mattplayschess.com/stockfish-cluster/ but I'm not sure how helpful it is. No official readme afaik.

Thanks. My IT skills are pretty good, but I'm well below programmer level and this is daunting

Well I have news: I got an email from tech support saying their provider has been having trouble.

After logging back in it took me 4 tries but, eventually, I rented the 1 BN/s server. I'd say it took about 15 mins to get it which was frustrating.

The NP/s is between 600 MN/s - 1300 MN/s depending on position. I think 800 MN/s is a fair average.

I tested it on my tactical testsuite, competing against latest SF (I think chessify only use SF 14 or 14.1) on my local machine. Local SF was running on Threadripper 3990X with 60 threads (faster than 120 threads by the way, probably due to lower clockspeed on 120).

My SF reaches 80 MN/s on average I'd say, so Chessify is about 10x faster. The tactical test results did appear to be in line with that, so it seems genuine.

Interesting. Thanks for the info.

Been thinking about this.

So for every 10x speedup you claim +10elo? So for 1 million times speedup would you claim only +60 elo? Really?
