The fact that software can be installed centrally helps others users to reproduce results. ---+++ Constraints Please remember this is a secondary use of the cluster which should in no way have an impact on the normal work of its regular users; try not to overload the system and have a look at the [[Tier3Monitoring][monitoring page]] before starting a large number of jobs ---++ Accounts ---+++ New Accounts To get a guest account for the T3 for the purpose of this Sherpa project please contact [[dmeister@phys.ethz.ch]]. ---+++ User Interface Please use the =t3ui03.psi.ch= machine to log in; this is a user interface machine and should not be used for heavy processing; in case this should be unavailable try =t3ui02.psi.ch= or =t3ui04.psi.ch=. ---+++ Troubleshooting If you have any problem with your account please have a look at the documentation in this TWiki (especially look at the page _User Information_ section on the [[WebHome][home page]]); if this does not help contact [[cms-tier3@lists.psi.ch]] and do not forget to mention that you have a _Sherpa Guest Account_. ---++ Software ---+++ CMSSW versions Both =CMSSW_5_3_9_sherpa2beta2= and =CMSSW_5_3_11_sherpa2beta2= are available. ---+++ New Install New (or newly configured) versions of Sherpa can be installed centrally in =/swshare/Sherpa/=; to get a folder there that is writable with your user account, please contact [[dmeister@phys.ethz.ch]]; note that you are expected to provide a complete installation/configuration manual for your version afterwards (example see below). ---+++ Available Versions * *1.4.3* versions in =/swshare/Sherpa/1.4.3= * *2.0-beta2* versions (from tarball) in =/swshare/Sherpa/2.0-beta2= * *2.0-beta2-svn* versions (latest beta2 from SVN includes fixed interface to !OpenLoops 0.3 in =/swshare/Sherpa/2.0-beta2-svn= ---++ Batch System We have 3 dedicated queues on the batch system that should be used for Sherpa related jobs; please do not use any of the other regular queues (we can of course also technically restrict you from using them but that is some additional work on our side). For general information about batch job submissions please read the [[HowToSubmitJobs][how to submit jobs page]]. ---+++ Queues * =sherpa.gen.q= for event generation (low priority queue) * =sherpa.int.long.q= for integration (with some time limits) * =sherpa.int.vlogn.q= for integration (without any time limits) ---+++ Limits 1 Queue job runtime limits * =sherpa.gen.q=: 12h * =sherpa.int.long.q=: 72h * =sherpa.int.vlong.q=: none 1 Queue job limits. How many jobs can be running in each of the queues: * =sherpa.gen.q=: 50 jobs * =sherpa.int.long.q=: 30 jobs * =sherpa.int.vlong.q=: 16 jobs 1 Per user job limits. Defines the maximum number of jobs a user can have running in each queue: * =sherpa.gen.q=: 30 jobs * =sherpa.int.long.q=: 15 jobs * =sherpa.int.vlong.q=: 10 jobs 1 *The policies are relaxed at night and on weekends*, so that the cluster can be taken by a bigger number of longer jobs: * Night time defined as weekdays from 19h - 4h, weekend time defined as Sat 4h - Mon 4h (timezone is Europe/Zurich) * =sherpa.gen.q=: 100 jobs * =sherpa.int.long.q=: 60 jobs * =sherpa.int.vlong.q=: 16 jobs ---++ Questions/Ideas Feel free do drop me an e-mail at [[dmeister@phys.ethz.ch]], contact me on Skype at _daniel-meister_, or come by my CERN office at _32/2-C13_ any time if you have questions or input about the setup. -- Main.DanielMeister - 2013-07-18
