EMI-ES and ATLAS

Summary of the open issues with EMI-ES which stop it being used by ATLAS

• No support in Condor-G
  • This is used for some ARC CEs, at some point it may not be necessary for ATLAS but for other VOs it is essential
• Walltime accounting - bug 3669
  • GLUE2 reports walltime as sum of walltime across all cores, but ATLAS counts walltime as real clock time independent of cores
  • The "fix" for this is to make NG schema also report the sum of cores walltime, but will not be released until ARC 6
    • Requires modifying aCT to convert back to ATLAS walltime for ARC 6, this needs to be very carefully coordinated
  • Sites may hack infoproviders to report ATLAS-friendly walltime with patch proposed in the bug report
• Change in memory units in 5.3.2 (no bug report)
  • Cannot use EMI-ES on servers < 5.3.2
• Proxy delegation issue when using ENV/PROXY - bug 3693
  • Stops true pilot jobs using EMI-ES
  • Underlying issue is that job.id.proxy is missing private key

Fixed issues

• Bad proxy mapping when submitting with different proxies in same process - bug 3685
  • Fixed in 5.4.1
• Inconsistent mapping of job states between gridftp and EMIES - bug 3683
  • Fixed in 5.4.1
• EMI-ES interface wrongly reports initial job status - bug 3640
  • Fixed in 5.3.2
