1. ALICE GSI Compile Cluster
Kilian Schwarz

2. icecream compile cluster

3. 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

4. alice icecream compile cluster

5. icecream usage go to any machine and start your environment
cd /misc/cbmsoft/tools/icecc/sbin
./iceccd -s lxb485.gsi.de -d
export PATH=/misc/cbmsoft/tools/icecc/bin:$PATH
==> which gcc
/misc/cbmsoft/tools/icecc/bin/gcc
eventually:
cd /misc/cbmsoft/tools/icecc-0.9.2/client
./icecc-create-env /usr/bin/gcc /usr/bin/g++
mv f46ba338131fd19eaea5c c91.tar.gz lxb255.tar.gz
export export ICECC_VERSION=/tmp/lxb255.tar.gz

6. cd $ALICE_ROOT gmake -j100 compile all of AliRoot in 3 minutes
icecream usage (2)
cd $ALICE_ROOT
gmake -j100
compile all of AliRoot in 3 minutes

7. 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
