Fiscal Year 2019 Quarterly Allocation Reductions

In fiscal year (FY) 2019, hours are planned by system and quarter. Projects may use hours ahead of quarterly targets up to the full annual allocation. Projects may continue to run jobs at low priority after exceeding their quarterly and/or annual allocations. Projects that do not use their full allotment of hours in a given quarter forfeit the under-used hours.

FY 2019 quarters include:

  • Quarter 1 - Oct. 1, 2018 - Dec. 31, 2018
  • Quarter 2 - Jan. 1, 2019 - March 31, 2019
  • Quarter 3 - April 1, 2019 - June 30, 2019
  • Quarter 4 - July 1, 2019 - Sept. 30, 2019.

Fiscal Year 2020 Quarterly Allocation Reductions

In FY 2020, shortly after Quarter 1, Quarter 2, and Quarter 3 end, allocations will be automatically adjusted to account for low utilization against planned usage. Percentage reductions are documented in the following table, and examples provided for a 100,000 allocation unit allocation.

Calendar Date If total charged usage is less than this much of initial allocation… …remove this much of initial allocation from unused balance Example 100,000
hour allocation
with zero usage
Example 100,000
hour allocation
with 6,000 hour/quarter usage
Example 100,000
hour allocation with
9,000 hour/quarter usage
  Removed Remaining Removed Remaining Removed Remaining
January 10 10% 15%     15,000 79,000 15,000 76,000
5% 30% 30,000 70,000        
April 10 20% 30%     30,000 58,000 30,000 52,000
5% 50% 50,000 50,000        
July 10 40% 25%         25,000 48,000
20% 75%     75,000 7,000    
10% 90% 90,000 10,000        

A linear burn rate is the underlying assumption; for projects with known non-linearities, adjustments will be made according to the plan (e.g., no reduction would be made on January 10 if no usage was planned for Quarter 1).
