Description Moe Jette 2015-09-16 07:49:49 MDT 
Account for the full value of active allocations in fairshare immediately, refund unused cycles at job end

Comment 2 Danny Auble 2015-09-18 08:50:45 MDT 
The current idea would be to add the time of the association's grp_used_cpu_run_secs to it's usage_efctv to determine how much time has been used for fairshare.  usage_efctv will grow over time as the grp_used_cpu_run_secs shrinks.  Combining them only when dealing with fairshare should give us the total number of decayed time (usage_efctv) with the number of allocated time (grp_used_cpu_run_secs).

This idea is open for alteration.
