All the T3 users are kindly invited to send some significant jobs to =short.q.validation= before 1st June and - if these jobs should fail - notify us on the usual channel =cms-tier3 AT lists.psi.ch= providing us a detailed report to troubleshoot the errors (we are also interested in building a comprehensive test-suite; so if you have jobs that you think are very different from everything else, please provide us the details). To avoid to affect the performances of your daily analyses only 1 CPU core from each of the oldest WN has been assigned to =short.q.validation= - Tot. 20 - and each user will be able to run a max of 4 concurrent jobs. Before 1st June silence from your side will mean that everything ran fine and based on this feedback *we'll configure the 3 production queues =short.q, all.q, long.q= to use the current release*. thanks for your kind cooperation,<br> the T3 Admins Team. ----------------- %FORMFIELD{"User"}% %FORMFIELD{"Date"}%
