to use the SL6 WNs you can:
   * login to a SL6 UI =t3ui[12,15,16,17,18,19]= and submit your jobs from there; *this is the simplest way*, when a job is launched from a SL6 UI the batch system *automatically* requests a SL6 WN  ( implicit =-l os=sl6= ). 
   * from a SL5 UI =t3ui0[2-9]=, by *explicitely* adding =-l os=sl6= to the =qsub= command; conversely when a job is launched from a SL5 UI the batch system *automatically* requests a SL5 WN ( implicit =-l os=sl5= ). 

Be aware that the CMSSW and the ROOT releases available in the SL6 WNs are different from the releases installed in SL5 WNs environment ; if you need a missing release please contact us by e-mail to =cms-tier3 AT lists.psi.ch= with =cms-tier3-users AT lists.psi.ch= in Cc to get it installed.
