Hi, will the job wrapper cleanup after the job *automatically*? If yes, will it be able to know what the job has left behind also outside the account home dir? Will it work on CE and WNs? What happens to the account after that? will it be reassigned to the same DN? will it be completely released? Oscar reply wasn't that clear. Will this scheme simplify the log files? How? Do you think it is a scalable solution? Shouldn't all of the above work anyway with a smaller number of accounts? With fairshare none of the VOs should be able to use the whole number of cpus, isn't the estimate a bit excessive? There is a difference between RBs/CEs/SEs/WNs needs. Assuming everything gets cleaned up and the scheme works perfectly and what becomes important the association between DN and job, and not anymore the unix account. We can potentially create only a number of accounts equal to the number of job slots on each WNs which means in the case of dual cpus without hyperthreads 2 per VOs: atlas01, atlas02; lhcb01, lhcb02;..... If the system could hadle it wouldn't it be a much better solution? cheers alessandra -- ******************************************** * Dr Alessandra Forti * * Technical Coordinator - NorthGrid Tier2 * * http://www.hep.man.ac.uk/u/aforti * ********************************************
