* *state, u_long32 start_time, u_long32 end_time, char level_char, const
* char *object_name, const char *name, double utilization)
*
* FUNCTION
* The entirety of all information passed to this function describes
* the schedule that was created during a scheduling interval of a
* Grid Engine scheduler. To reflect multiple resource debitations
* of a job multiple calls to serf_record_entry() are required. For
* parallel jobs the serf_record_entry() is called one times with a
* 'P' as level_char.
*
* INPUTS
* u_long32 job_id - The job id
* u_long32 ja_taskid - The task id
* const char *type - A string indicating the reason why the
* utilization was put into the schedule:
*
* RUNNING - Job was running before scheduling run
* SUSPENDED - Job was suspended before scheduling run
* MIGRATING - Job being preempted (unused)
* STARTING - Job will be started
* RESERVING - Job reserves resources
*
* u_long32 start_time - Start of the resource utilization
*
* u_long32 end_time - End of the resource utilization
*
* char level_char - Q - Queue
* H - Host
* G - Global
* P - Parallel Environment (PE)
*
* const char *object_name - Name of Queue/Host/Global/PE
*
* const char *name - Resource name
*
* double utilization - Utilization amount
*
* NOTES
* MT-NOTE: (1) serf_record_entry() is MT safe if no recording function
* MT-NOTE: was registered via serf_init().
* MT-NOTE: (2) Otherwise MT safety of serf_record_entry() depends on
