Quarterly Allocation Reductions

MPP (or computational) repositories that haven't used (charged) significant amounts of time are adjusted at certain times during the year by transferring a part of the unused balance to the corresponding DOE Office reserve.

Allocation Year 2016

The following schedule will be used for allocation year 2016 (which runs 12 January 2016 through 9 January 2017). 

(NOTE: Since we have implemented the scavenger queues on the computers and with the changes anticipated by bringing in the cori Phase 1 and Phase 2 machines, we are deviating from our standard Quarterly reduction schedule for AY 2016.)
