4. Hans Wenzel CMS 101 September 13 2004 How to get started at UCSD  (1) request access -> send your fnal krb5 principal name to fkw@fnal.gov and request access to sdsccaf as cms user (2) prepare your account at t2cms03 -> create.k5login just like ~fkw/.k5login except replacing fkw appropriately (3) do a simple test submission cp ~fkw/test.tgz. cp ~fkw/submit.sh edit./submit.sh appropriately (replace fkw byt your username, replace outLocation with one of your dir on t2cms03 of your choice.) make sure you have a krb5 ticket. E.g. do "klist". If your ticket doesn't show up then do kinit../submit.sh

9. Hans Wenzel CMS 101 September 13 2004 Available disk areas /storage/data/ /storage/data1/ /storage/data2/uaf/ Caution!!! not backed up, Right now no quotas ----> be nice to each other General Setup: source "/afs/fnal.gov/ups/etc/setups.csh" source /afs/fnal.gov/files/code/cms/setup/cshrc fnal setup dcap -q +unsecured setup kerberos setup fbsng

10. Hans Wenzel CMS 101 September 13 2004 Available Data sets: /storage/data2/uaf/tutorial/zpmumu/PoolFileCatalog.xml InputCollections = /System/myDST/zprime_mumu /storage/data2/uaf/tutorial/h300eemm/PoolFileCatalog.xml InputCollections = /System/myDST/h300eemm

11. Hans Wenzel CMS 101 September 13 2004 Integrating the Desktop  Besides central computing make use of the powerful PC's running linux (plenty of disk, cpu, freedom, it's all yours..)  Created CMS desktop workgroup containing everything you need to run CMS software on your PC (afs....). CMS software is kept up to date in AFS.  Two rpms need to be installed in addition GNU.LANG_gcc-alt-3.2-3.i386.rpm GNU.LANG_gcc-alt-3.2.3-2.i386.rpm
