Workload Management System Ref gLite-3.2 User Guide 7 The purpose of the Workload Management System (WMS): To accept user jobs To assign them to the most appropriate Computing Element To record their status To retrieve their output The WMS used to be called Resource Broker (RB). The service is called gLite-WMS.

CREAM Job States 25 StatusDescription REGISTEREDthe job has been registered but it has not been started yet. PENDINGthe job has been started, but it has still to be submitted to the LRMS abstraction layer module (i.e. BLAH). IDLEthe job is idle in the Local Resource Management System (LRMS). RUNNINGthe job wrapper, which "encompasses" the user job, is running in the LRMS. REALLY-RUNNINGthe actual user job (the one specified as Executable in the job JDL) is running in the LRMS. HELDthe job is held (suspended) in the LRMS. CANCELLEDthe job has been cancelled. DONE-OKthe job has successfully been executed. DONE-FAILEDthe job has been executed, but some errors occurred. ABORTEDerrors occurred during the "management" of the job, e.g. the submission to the LRMS abstraction layer software (BLAH) failed. UNKNOWNthe job is an unknown status.
