Work on your cluster

You can use Auriga outside of this site, in this page you will see how to configure a cluster with 3 machines (workers),, (you can use all the machines you want), on the three machines Download auriga and configure the environment variable $AURIGA_ROOT

create a Perft (command line)

on launch

$AURIGA_ROOT/auriga --generate-ini $AURIGA_ROOT Ntask "FEN" DEPTH
example create a perft with 100 tasks and depth 10:
$AURIGA_ROOT/auriga --generate-ini $AURIGA_ROOT 100 "rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1" 10

remove the host entry in worker file (example $AURIGA_ROOT/worker/stockfish.worker.ini)
on 3 workers launch the command (replace stockfish with your engine)
$AURIGA_ROOT/auriga --task $AURIGA_ROOT stockfish 6EDBD9C7-B1B5-C402-FEDD-1CE33A016572  2AD20F3E-C861-E557-250E-0F2871309DGG

in windows machine launch
%AURIGA_ROOT%\auriga.exe --task %AURIGA_ROOT% stockfish 6EDBD9C7-B1B5-C402-FEDD-1CE33A016572  2AD20F3E-C861-E557-250E-0F2871309DGG
