New engine releases & news 2021

[jshriver]

After a lot of work and testing, Loki 3.0 is now released.

The engine looks wonderful, just played a game and enjoyed its style.

I made linux binaries for 64bit armv8 and 32bit armv7 (pi4 and pi0)

Thanks Vladimir!

Unfortunately, even my Loki 2.0.0 results could not appear on our list yet so 3.0 will have to wait a bit I'm afraid.

Well, I've made an exception, +500 Elo was to tempting, so I started a gauntlet with 3.0.0.

I am happy to hear that! I hope the results on CCRL will be as good as the ones from my own tests!

Summer is near and my garden needs some work to do the next weeks so I released RubiChess 2.1.

For those with slightly older machines, I made (hopefully) a Windows 64bit Igel 3.0.0 for "modern" aka popcnt, sse4.1 but no AVX/BMI2 instructions.

If there are any problems let me know, I just installed Visual Studio Community to figure out how to do this.

Thanks for your efforts, but keep in mind that these are not official Igel binaries. For those people who have a custom needs for specific CPU architecture they ask me in the main Igel thread http://talkchess.com/forum3/viewtopic.p ... 79#p889179 and I compile binaries for them usually with-in the same day to let them run Igel tests. The advantage of such method is that I compile (and check) a custom build exactly targeted for a given cpu architecture, so this gives maximum performance for Igel.

For official tournaments/rating lists I encourage to use only official binaries from github page as those give the maximum performance and accurate performance rating matters a lot for rating list.
