Please bookmark it and explore the T3's capabilities. Information about the two T3 mailing-lists: * Subscribe to the =cms-tier3-users@lists.psi.ch= mailing list using [[https://psilists.ethz.ch/sympa/info/cms-tier3-users][its web interface]] ([[https://psilists.ethz.ch/sympa/arc/cms-tier3-users][list archives]]): this mailing list is used to communicate information on Tier-3 matters (downtimes, outages, news, upgrades, etc.) or for discussions among users and admins. * To privately contact the CMS Tier-3 administrators write to =cms-tier3@lists.psi.ch= instead ; no subscription is needed for this mailing list. * Both lists are read by the administrators and are archived. You can submit support requests to either of them but emails addressed to the =cms-tier3-users@lists.psi.ch= are read by *everyone* so they could get answered better and sooner, especially if you ask about specific CMS software ( CRAB3, CMSSW, Xrootd, ... ) ---+++ T3 policies Read and follow the Tier3Policies ---+++ Linux groups Each T3 account belongs to a primary group and to a common secondary group %GREEN%cms%ENDCOLOR% that's used for shared files like the ones downloaded on demand by the [[https://cmsweb.cern.ch/phedex/][PhEDEx]] service ; the primary groups are : | *ETHZ* | *UniZ* | *PSI* | | =%ORANGE%ethz-ecal%ENDCOLOR%= | =uniz-higgs= | =%TEAL%psi-bphys%ENDCOLOR%= | | =%BROWN%ethz-bphys%ENDCOLOR%= | =%BLUE%uniz-pixel%ENDCOLOR%= | =%PURPLE%psi-pixel%ENDCOLOR%= | | =%RED%ethz-ewk%ENDCOLOR%= | =%ORANGE%uniz-bphys%ENDCOLOR%= | | | =%BLUE%ethz-higgs%ENDCOLOR%= | | | | =%PURPLE%ethz-susy%ENDCOLOR%= | | | These primary groups allow : * an easy =/pnfs /shome /scratch /tmp= space monitoring * an easy batch system monitoring * to protect the user =/pnfs= files since only him/her will be able to delete his/her own files ; that's usually *NOT* guaranteed by the others CMS T1/T2/T3 ! * to protect the T3 "group dirs" =/pnfs/psi.ch/cms/trivcat/store/t3groups/= since only the group members will be able to upload/delete their own files For instance these are the %BLUE%primary%ENDCOLOR% and the %GREEN%secondary%ENDCOLOR% group of a generic T3 account : <pre> $ id auser uid=571(auser) gid=532(%BLUE%ethz-higgs%ENDCOLOR%) groups=532(%BLUE%ethz-higgs%ENDCOLOR%),500(%GREEN%cms%ENDCOLOR%) </pre> The following is a partial list of the private user dirs =/pnfs/psi.ch/cms/trivcat/store/user/= on which it's well visible the dirs protection : <pre> $ ls -l /pnfs/psi.ch/cms/trivcat/store/user | grep -v cms total 56 drwxr-xr-x 2 alschmid %ORANGE%uniz-bphys%ENDCOLOR% 512 Feb 21 2013 alschmid drwxr-xr-x 5 amarini %RED%ethz-ewk%ENDCOLOR% 512 Nov 7 15:37 amarini drwxr-xr-x 2 arizzi %BROWN%ethz-bphys%ENDCOLOR% 512 Sep 16 17:49 arizzi drwxr-xr-x 5 bean %TEAL%psi-bphys%ENDCOLOR% 512 Aug 24 2010 bean drwxr-xr-x 5 bianchi %BLUE%ethz-higgs%ENDCOLOR% 512 Sep 9 09:40 bianchi drwxr-xr-x 98 buchmann %PURPLE%ethz-susy%ENDCOLOR% 512 Nov 5 20:36 buchmann ... </pre> The following are the T3 "group dirs" =/pnfs/psi.ch/cms/trivcat/store/t3groups/= ; since they're meant to serve a group they belong to the =root= account, accordingly no user will be able to remove these dirs : <pre> $ ls -l /pnfs/psi.ch/cms/trivcat/store/t3groups/ total 5 drwxr%GREEN%w%ENDCOLOR%xr-x 2 root ethz-bphys 512 Nov 8 15:18 %BROWN%ethz-bphys%ENDCOLOR% drwxr%GREEN%w%ENDCOLOR%xr-x 2 root ethz-ecal 512 Nov 8 15:18 %ORANGE%ethz-ecal%ENDCOLOR% drwxr%GREEN%w%ENDCOLOR%xr-x 2 root ethz-ewk 512 Nov 8 15:18 %RED%ethz-ewk%ENDCOLOR% drwxr%GREEN%w%ENDCOLOR%xr-x 2 root ethz-higgs 512 Nov 8 15:18 %BLUE%ethz-higgs%ENDCOLOR% drwxr%GREEN%w%ENDCOLOR%xr-x 2 root ethz-susy 512 Nov 8 15:18 %PURPLE%ethz-susy%ENDCOLOR% drwxr%GREEN%w%ENDCOLOR%xr-x 2 root psi-bphys 512 Nov 8 15:18 %TEAL%psi-bphys%ENDCOLOR% drwxr%GREEN%w%ENDCOLOR%xr-x 2 root psi-pixel 512 Nov 8 15:18 %PURPLE%psi-pixel%ENDCOLOR% drwxr%GREEN%w%ENDCOLOR%xr-x 2 root uniz-bphys 512 Nov 8 15:18 %ORANGE%uniz-bphys%ENDCOLOR% drwxr%GREEN%w%ENDCOLOR%xr-x 2 root uniz-higgs 512 Nov 8 15:18 uniz-higgs drwxr%GREEN%w%ENDCOLOR%xr-x 2 root uniz-pixel 512 Nov 8 15:18 %BLUE%uniz-pixel%ENDCOLOR% </pre> ---+++ User Interfaces ( UI ) Six homogeneous User Interfaces ( UI ) are available to both develop your programs and to send them as computational jobs to the batch system by =qsub= : %INCLUDE{"Tier3Policies" section="UisPerGroup"}% 1. Login into a =t3ui1*= machine by =ssh= ; use =-Y= or =-X= flag for working with X applications; you might also try to [[UserNxClientInstallation][connect by NX client]], which allows to work efficiently with your graphical applications<pre> ssh -Y username@t3ui12.psi.ch </pre> 1. *If you are an external PSI user you'll have to change your initial password the first time you log in*; simply use the standard =passwd= tool. 1. Copy your grid credentials to the standard places, i.e. to =~/.globus/userkey.pem= and =~/.globus/usercert.pem= and make sure that their files permissions are properly set : <pre> -rw-r--r-- 1 feichtinger cms 2961 Mar 17 2008 usercert.pem -r-------- 1 feichtinger cms 1917 Mar 17 2008 userkey.pem </pre> For details about how to extract those =.pem= files from your CERN User Grid-Certificate please read [[https://gridca.cern.ch/gridca/Help/?kbid=024010]]. 1. Source the grid environment associated to your login shell: <pre> source /swshare/psit3/etc/profile.d/cms_ui_env.sh # for bash source /swshare/psit3/etc/profile.d/cms_ui_env.csh # for tcsh </pre> 1. ( Optional ) Modify your shell init files in order to automatically load the grid environment ; for BASH that means placing :<pre> [ `echo $HOSTNAME | grep t3ui` ] && [ -r /swshare/psit3/etc/profile.d/cms_ui_env.sh ] && source /swshare/psit3/etc/profile.d/cms_ui_env.sh && echo "UI features enabled" </pre> into your =~/.bash_profile= file. 1. Run =env|sort= and verify that =/swshare/psit3/etc/profile.d/cms_ui_env.{sh,csh}= has properly activated the setting <pre>X509_USER_PROXY=/shome/$(id -un)/.x509up_u$(id -u)"</pre> ; that setting is *crucial* to access a CMS Grid SE from your T3 jobs. 1. You must register to the [[https://lcg-voms.cern.ch:8443/vo/cms/vomrs?path=/RootNode][CMS "Virtual Organization"]] service or the following command =voms-proxy-init -voms cms= won't work. [[https://twiki.cern.ch/twiki/bin/view/CMSPublic/SWGuideLcgAccess#How_to_register_in_the_CMS_VO][CERN details about that]], e.g. who is your representative. 1. Create a proxy certificate for CMS by: <pre> voms-proxy-init -voms cms </pre> If the command =voms-proxy-init -voms cms= will fail then run the command with an additional =-debug= flag, the error message will be usually sufficient for the T3 Admins to troubleshoot the problem.</br> 1. Test your access to the PSI Storage element by the =test-dCacheProtocols= command ; you should get an output like this (possibly without failed test) ; sometime the XROOTD-WAN-* tests might get stuck due to a I/O traffic coming from Internet but as a local T3 user you're actually supposed to use the XROOTD-LAN-* I/O doors that are protected from the Internet users, so you can simply skip the XROOTD-WAN-* tests by either pressing Ctrl-C or by passing the option : %ORANGE%-i "XROOTD-LAN-write"%ENDCOLOR% ( see below )%TWISTY%<pre> $ test-dCacheProtocols Test directory: /tmp/dcachetest-20150529-1449-14476 TEST: GFTP-write ......

Please notice that this Skype account is meant as a 2nd level of support ; 1st of all *always* write an email to =cms-tier3@lists.psi.ch= describing your error, possibly how to reproduce it, on which UI you're working and providing as many meaningful logs you can. ---+++ Backup policies The user =/shome= files are backuped *every hour*, max 36h, and every day, max 10 days ; recover a file is as simple as running a =cp= command ; Further details are here HowToRetrieveBackupFiles. NO backups are instead available for the =/scratch= or =/pnfs= files, be careful ! ---+++ Web browsing your =/shome= files on demand We don't provide a =http{s}://= URL to browse your =/shome= logs/errors/programs because there was always a modest interest about a such web portal but you can turn on a private website rooted on an arbitrary %BLUE%dir%ENDCOLOR% of yours by simply using SSH + Python like in the following example ( replace =t3ui12= with your daily =t3ui= server and the %BLUE%dir%ENDCOLOR% with a dir meaningful for your case, for instance %BLUE%~%ENDCOLOR% ): <pre> ssh -L 8000:t3ui12.psi.ch:8000 t3user@t3ui12.psi.ch "killall python ; cd %BLUE%/mnt/t3nfs01/data01/shome/ytakahas/work/TauTau/SFrameAnalysis/Scripts/%ENDCOLOR% && python -m SimpleHTTPServer" </pre> open your Web browser to the page http://localhost:8000/ . That's it. the preliminary =killall python;= command is meant to kill a previous =python -m SimpleHTTPServer= run that might be still active but if you've other =python= programs they will be killed too ; in that case delete the initial =killall python;= command and kill the =python -m SimpleHTTPServer= previous command by : <pre> t3ui12 $ kill -9 `pgrep -f "^python -m SimpleHTTPServer*"` </pre> if some other T3 user is already using the =t3ui12.psi.ch:8000= port then use another port like %GREEN%8001%ENDCOLOR%, 8002, etc.. : <pre> ssh -L 8000:t3ui12.psi.ch:%GREEN%8001%ENDCOLOR% t3user@t3ui12.psi.ch "killall python ; cd %BLUE%/mnt/t3nfs01/data01/shome/ytakahas/work/TauTau/SFrameAnalysis/Scripts/%ENDCOLOR% && python -m SimpleHTTPServer %GREEN%8001%ENDCOLOR%" </pre>
