Interesting timing!

I was just getting ready to post something about this as well.

I had noticed the same thing, but wasn't sure if I was doing something wrong (although I found that unlikely, since the exact same steps worked with smaller hash sizes).

With hash 1024 MB, single thread, initial position, first search (all searches are "go infinite") took 111 seconds to complete iteration 30.

Same settings, just a "stop" and "go infinite" immediately afterwards to see what it's like with the hash populated from the previous search, 29 seconds.

Much faster, as expected.

Now saving the hash, closing and reopening the engine, loading the hash, and the search took 79 second to complete iteration 30.

That number is even a bit misleading, because it got a bit unlucky and spent almost all of its time resolving 3 consecutive fail highs/fail lows on iteration 30.

It completed iteration 29 nearly instantly (took around 80-90 seconds with an empty hash).

So, the save/load hash worked as expected for a 1024 MB hash.

Now, times for the same setup with the only change being a 2048 MB hash.

I'll just give the times and skip the description of each run:

91 seconds
21 seconds
91 seconds

This has been consistent across all the runs I've tried in different positions.

The loaded hash just seems not to provide any benefit at all when >=2 GB.

At the moment the scenario's a bit funny, because asmFish's save/load works with the larger hash sizes, but it also doesn't have the changed hash replacement for infinite analysis (or if it does, it doesn't seem to work as well, as I can't get it to retain found values for lines in forwards-backwards nearly as consistently as I can with Daniel Jose's nice version) , so I get to pick one or the other feature for now :)

Hopefully the issue is not so difficult to fix; I really appreciate all the work that's gone into this!

Best to check the real working of reload of hash with useful entries already "found" are positions with single best moves that need some time fo be found with empty hash and quickly get much higher stable eval after few plies of backward solving.

I always use this fine Josten- study:

[d]2n3B1/6p1/2P2p2/1p3P1p/1p1nK2P/3P4/4N2p/7k w - - 0 1

1.Ke3! (e.g. 1...Nxe2 2.Kf2 Nc3 3.Bb3!)

SF doesn't find that in single variant mode within 2 minutes because of nullmove- pruning.
Sting, SF MateFinder and branches with nullmove to be switched off are some faster and 2MV brings up the best move soon too even at default settings.

If the reload of hash with already found or shown solution works, (eval has to be one of clear white win) 1.Ke3 has to be the first output- move at once after restart, if 1.Kxd4? arises at first again for several iterations, reload has failed.

Latest S_XPro works up to 2 G hash, with 4 and more it fails

Indeed. That is a better type of test in general, and I had done some of those as well.

I posted what I did to make it as easy to reproduce as possible, not that your example is all that hard to work with :)

At any rate, for completeness I did quick runs on this position, doing what I had to get it to see a favorable white eval from the root with Ke3, saving the hash, closing the engine, starting it again, loading the hash, and running the analysis.

Here are the first 6 iterations of each:

256 MB hash

Same issue crops up at 2048 MB hash. Using stockfish_x64_modern_170724_savehash.exe in all examples (this post and the previous).

As I said above, hopefully it's something fairly easy to fix; it's a very nice functionality to have, even limited to smaller hash sizes.

Hi Peter - very nice position. When I first looked at it, I thought Ke3 was a good drawing move, much to my surprise, it wins! This is the latest McBrain 3.0 which is now expected to be released this Saturday.

28sec. for finding 1.Ke3 and 31 for winning eval is fine, if you switch off nullmove, TTS will be even faster proably.

And, as said, many engines get 1.Ke3 almost at once too with 2MV mode, then it still takes more or less time to find 3.Bb3 (or even only at 4th or 5th in some lines) which is so to say the zugzwang- highlight, and not until then eval starts climbing.

Here's how successfully after restart of GUI and engine reloaded hash of 4G has to look like as for the output, if it was saved before with full hash and after "finding" and "understanding":
