After a brief review of the core functionality and presenting statistics on the deployment scale we focus on new features (L&B proxy -- a lightweight component computing a partial view on grid job state based on locally gathered information only) and new foreseen applications -- support for computing grid usage statistics and Computing Element reputability ranking used as a feedback information for grid job scheduling.
We also present a longer ter...
