Detailed Description¶
Scheduler-specific SEG module implementations use this API to issue events to
the Job State Monitor. Events occur whenever a job is placed in the
scheduler's queue (PENDING), begins execution (ACTIVE), terminates
successfully (DONE), or ends abnormally (FAILED).
A SEG module should register an event with the Globus event driver (most likely
using either the Globus Callback or Globus XIO interfaces) in its activation
function and then return. All events should be triggered from callbacks. When
the SEG detects that it should terminate, it will deactivate the SEG module it
started. The SEG module should wait for any outstanding callbacks to subside
and before returning from its deactivation function to ensure that all events
will be properly dispatched. After deactivation is complete, the SEG will
unload the shared module and terminate.
