Stockfish 2.1.1 maintenance release available

Post by Jim Ablett »

This is Stockfish 2.1.1

Builds for Windows/Linux & Android.

Available from Jim's site: http://jimablett.hostwebs.com/
& soon from official site : http://www.stockfishchess.com/

This is a maintenance release to fix book reading
issue reported by some user, as an added benefit Jim's build should be
now a little faster on Intel CPU (4% on 64 bits and almost 6% on 32
bits).

This is a non functional change release so there is no need to retest
Stockfish for people that has already done, for people still to test
we suggest to use this one because should be a bit faster on Intel
hardware.

Stockfish Team.

Hi Michael,

I am getting a segmentation fault also when final optimizations are applied to the compilation. I think the new src code breaks something in 64 Linux.
I'll continue testing this to see if I can produce a working compile.

I can't install the 64-bit Windows version under Sabayon/Wine. Previous versions were fine.

I suppose this was done with the Intel compiler?...

Hi Ernest,

I always produced the fastest executables using the Intel compiler, except with the new source code
which ran faster on my AMD systems using Msvc compiler. Marco reported that the Intel builds run faster
on his Intel hardware and since the majority of users will probably be using Intel cpus, he
wanted the Intel compiles to be the ones distributed.

I have re-compiled both Windows & Linux 64 bit compiles.

The 64 bit Linux compile was not functioning at all. Should be a bit faster than previous compiles now as well.
It works now after changing the profiling options from '-fprofile-generate / -fprofile-use' to
'-fprofile-arcs' / -fbranch-probabilities. I was getting a segmentation error with the compiled exe.

I have recompiled the Windows 64 bit version. No different from before except it will now run
correctly for users using Linux 64 bit Wine.

Hi Jim,

On my Core 2 Duo, 1 core used, infinite analysis from start_position:
64-bit: 2.1.1 is 6.3% faster than 2.1
32-bit: 2.1.1 is 5.1% faster than 2.1

On 64-bit, that should translate to +6 Elo... :)
