Do you know if these JAVA engines run smoothly with cutechess + concurrency ?

Yes, it does.
I use cutechess + concurrency e.g. for my 60 sec + 0.6 sec rating list.

Belofte 2.1.2 released on 32/64 bit linux/windows/mac.

• Slight improvement over 2.1.1 (and its never released fix 2.1.1.2). Elo difference about 100, but given past experience with 2.1.1 release, lets wait confirmation from CCRL lists.

• No longer segfault on MacOS X on exit.

• No longer stops sometimes on move 256, lets hope this fixes the issue some have seen on move 64 or 128.

• Some primary endgame evaluation.

• Movelist generation and other speedups.

Other changes, see README.md.

Berserk 4.1.0 is out now.

Minor evaluation and search changes. Most significant changes are NPS improvements and a major bug fix that is present in release 4.0.0.

Downloads available here: https://github.com/jhonnold/berserk/releases/tag/4.1.0

Belofte 2.1.2 released on 32/64 bit linux/windows/mac.

Thanks Yves. On my 64-bit Win10 PC the 32-bit exe runs faster than the 64-bit one so that is what I am using.

Just released Cheng 4.41
link: http://vlasak.biz/cheng

the improvement is modest this time (I'm playing with fire - no pun intended , estimated +15 against other engines (about half of 4.40 vs 4.39)
(self-play hyperbullet 56% against 4.40 so who knows, I usually get about half of self-play) - my apologies to the testers for not jumping hundreds of Elo points

+55 Elo in my chess960 testing:

Needs more games, but unlikely to change too much.
