Glexec / Deployment at IN2P3-CC (1) First setup at CCIN2P3 (may/july 2009) –Setuid/SCAS mode –Glite-WN shared on AFS –But additional module « glite-GLEXEC_wn » not entirely shareable /etc/ld.so.conf –no static version of Glexec –LD_LIBRARY_PATH not an alternative because of setuid /etc/syslog.conf –Grid environment variables problem glexec cleared most of the environment variables But a glexec wrapper should be now available to rebuild the grid environment –2 load-balanced SCAS nodes Not really tested with a real production load Tighten collaboration –With Glexec developers –With VO testers (lhcb/atlas) 2010/05/075Pierre Girard / CAF / Glexec et CREAM CE

Glexec / Deployment at IN2P3-CC (2) New deployment (2010) –With an enhanced version of Glexec_WN –By the end of may (hopefully) –By starting with SCAS service –But, by probably switching from SCAS to ARGUS Service asap Requires to be tested and well-understood 2010/05/076Pierre Girard / CAF / Glexec et CREAM CE
