What does "use or lose allocation" mean?
Allocations of node hours are segmented by allocation cycle quarters. A summary of these quarters is included bellow:
Quarter 1: Nov 1, 2015 - Jan 31, 2016
Quarter 2: Feb 1, 2016 - Apr 30, 2016
Quarter 3: May 1, 2016 - Jul 31, 2016
Quarter 4: Aug 1, 2016 - Oct 31, 2016
Node hours designated for a specific allocation cycle quarter must be used during that quarter. Any node hours that go unused by the close of an allocation cycle quarter will be forfeited.
The quarterly node hour plan is not a limit. Projects may use node hours ahead of the quarterly plan until the annual allocation is fully used.
