Re: New Tool

Update: mea doesn't run under wine, so it won't run under Linux but mrl.exe runs fine. mea.exe seems to be a program compiled into a python binary it seems it turns out that mea is actually ferdy's open source https://github.com/fsmosca/Multiple-move-Epd-Analyzer and Ed's tool is probably built on t...

Re: New Tool

it's not a passion, but a religion (biased, naturally)
make silly demands, spit in every direction because there is only one true "god" :D sounds familiar?

I'd rather not use closed-source software coming from a windows platform.
Then don't use it, the world doesn't revolve around Linux fanboys :)
(to be clear, I like Linux, but I hate Linux fanboys)

Please consider releasing the source-code so that macos and linux users also can use it.
Why can't you simply use Wine? (unless you've already tried and it didn't work)

Re: A complete 2000 lines of code engine => not any more

With around 5000 lines today and what about the 3rd party json.hpp abomination it depends on? that's nearly 10k sloc (22k loc) => beyond ugly for something as simple as parsing a json... why do you even need that for a chess engine I don't understand, but it's your call of course for inspiration, y...

Re: Search speed in AMD

My experience with AMD so far is that AMD loves everything cached in registers. Any memory access (assuming in L1) is much slower than on Intel, or perhaps it's the other way around and AMD is much faster when executing reg-reg opcodes) Optimizing compilers do this for you, obviously, so I don't see...

Re: Komodo - is it worth it.

Komodo - is it worth buying. That is the question . so far your tests show that Komodo is the "best engine money can buy" (to paraphrase Houdart's quote) btw you still haven't answered Paloma's question; unless you're an official tester (in which case you wouldn't ask) or have actually bought it ((...

Re: Removing Large Arrays

First you have to compare apples to apples, i.e. the patch contains functional changes and produces different values than the old tables. So you bake the new formula into tables (of bytes, not ints, that is 4 times smaller), then you can bench hundreds/thousands of relevant EG positions and let us k...

Re: Removing Large Arrays

Often, I test the speed of different function methods. The results indicate the fixed array PushToEdges[] seems to be faster on average: 10 second test ... PushToEdges 16519006400 push_to_edge 16610155136 nonsense, the compiler completely eliminates the inner loops, so it boils down to nothing (bus...

Re: Removing Large Arrays

no way the formula is faster if the table is in L1
the patch seems to do more than what was posted here, we were misled.
it replaces two tables plus it allegedly fixes some EG bug, so there are functional changes (also tables differ from formulas).
so it's not about performance at all.
