Stockfish 1.7.1: PGO GCC 4.5 vs. ICC 11.1

Howto PGO-compile Stockfish mit GNU C++ 4.5 am Mac

Voraussetzung am Mac sind die bereits installierten Apple Developer Tools Xcode. Am einfachsten gelingt nun das Aufspielen, der gerade fertiggestellten GNU Compiler Suite 4.5, mittels MacPorts. Da der Quellcode erst lokal übersetzt wird und diverse Abhängigkeiten vorher berücksichtigt werden müssen, dauert der ganze Vorgang leider eine gefühlte Ewigkeit. Wenn alles fertig installiert ist, dann das vorhandene Makefile von Stockfish 1.7.1 um nachfolgende Zeilen ergänzen. Zum Abschluß noch im Terminal "make osx-profile" eingeben. Fertig ist das GNU C++ 4.5 Profile-Guided Optimization (PGO) Kompilat von Stockfish 1.7.1.

Ergänzungen zum Original Stockfish Makefile:

osx-pgo-gen:
$(MAKE) \
CXX='g++-mp-4.5' \
CXXFLAGS="$(GCCFLAGS)" \
CXXFLAGS+='-march=core2 -msse3 -m64 -fprofile-generate' \
LDFLAGS+='-march=core2 -msse3 -m64 -fprofile-generate' \
all

osx-pgo-use:
$(MAKE) \
CXX='g++-mp-4.5' \
CXXFLAGS="$(GCCFLAGS)" \
CXXFLAGS+='-march=core2 -msse3 -m64 -fprofile-use' \
LDFLAGS+='-march=core2 -msse3 -m64 -fprofile-use' \
all

osx-profile:
@touch *.cpp *.h
$(MAKE) osx-pgo-gen
@echo ""
@echo "Running benchmark for pgo-build ..."
@$(PGOBENCH) > /dev/null
@echo "Benchmark finished. Build final executable now ..."
@echo ""
@touch *.cpp *.h
$(MAKE) osx-pgo-use
@rm -f *.o *.gcda bench.txt

Mephisto IV - µ-Max 4.8

Wissen hilft: µ-Max 4.8 rechnet über 5 Halbzüge tiefer, aber Ed Schröders Mephisto MM IV weiß einfach, dass ein Springer allein nicht zum Mattsetzen genügt. Darum "opfert" er im 65. Zug seinen Läufer für die beiden Bauern.

Der Emulator für einige alte Mephisto Schachcomputer kann von Ed Schröders Homepage geladen werden.

Mephisto III S (Glasgow) - TSCP 1.81

Bei der vierten Microcomputer Schach-WM vergab die ICGA 1984 in Glasgow den Weltmeister-Titel an die vier punktgleichen Erstplatzierten. Neben Fidelity Elite, Conchess und dem Mephisto III S erhielt auch Richard Lang mit Psion seinen ersten WM Titel.

Nachfolgend eine blitzsaubere Leistung des kultigen Ex-WM Mephisto III S. Mit nur ein paar Dutzend berechneter Stellungen pro Sekunde besteht er gegen TSCP 1.81, trotz dessen über 150.000 Knoten pro Sekunde. Der 26 Jahre alte Schachcomputer wurde mittels MESS in maximaler Geschwindigkeit emuliert und als Winboard Engine in die SchachGUI eingebunden.
