ALICE GSI Compile Cluster Kilian Schwarz

icecream compile cluster

setup (permanent location still needed) start scheduler and monitor on server (currently lxb485: LSF7 test machine, not used in production) scheduler -d icemon & ... start client daemons on Wns (currently lxb480- lxb485: LSF7 test machines) if they should take load, the daemons should be started as „root“ lxb483:~# whoami root lxb483:~# iceccd -s lxb485 -d

cluster growth the compile cluster can grow dynamically feel free to add more resources as long as you have root rights on your machine all architectures (Debian Sarge, Etch, 32/64, Mac, ...) can be added permanent location for the main servers to be found
