Special Topics

Flavia

In the daily WLCG operations meeting, general overload of grid components (SE) are reported. There has been a discussion on how to cope with the fact of overloading SE's. This could essitially be done by :

  • Limit the number of requests, which is possible with known clients but could be challenge doing analysis.
  • Making clients smarter, e.g. backing off if load increases.
  • Let the SE hardware grow with the number of CPU's deployed at a site.

Doris
