Inside Auriga

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) 192.168.1.100, 192.168.1.101, 192.168.1.102 (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 192.168.1.100 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
