Starting Proof at LRZ

Start Master on lcg-lrz-proof

(Email instructions PC 03Mar10)

ssh lmu-etp-user@lcg-lrz-proof.grid.lrz-muenchen.de
cd proof/
source setup_root.sh  # source ~/local/root/init_root_5.24_i386
sh start-xrootd.sh 

(There are also the scripts stop-xrootd.sh and check-xrootd.sh)

Start Slaves on LRZ WNs

(Email instructions PC 03Mar10) The slaves run on lx64a[59-68] and lx64e[14-137] with only one core per node (-> 134 workers).

ssh uh351ac@lx64ia3.lrz-muenchen.de
cd proof_o/
sh start_all_ae.sh
(to stop: stop_all_ae.sh)

Changing number of slaves:

  • Edit /home/grid/lcg/home/uh351ac/proof_o/config/proof.conf (rather use IPv4 adresses!)
  • Adjust start_all_ae.sh and stop_all_ae.sh accordingly
  • start_20_ae.sh/stop_20_ae.sh available
  • Or do: proof->SetParallel(n) to only use n nodes.

Start Proof Session from elsewhere

# this was needed to start applications on all slave nodes
