[Halld-offline] OSG core-hours / yer

[Richard Jones]

Hello Dave,

It really depends on how much we can get resources from our member
institutes to come forward. So far I have the following estimates of what
we might reasonably expect over the coming year from OSG.

   1. UConn - 10M core hours
   2. FSU - 5M core hours (so far, more on the horizon)
   3. Northwestern - 2M core hours
   4. Regina - 2M core hours (so far, maybe more can be found)
   5. Indiana - 4M core hours
   6. Florida International - 2M core hours
   7. opportunistic cycles - 10M core hours (my estimate, based on
   experience so far)

I know CMU has significant resources to offer, but so far they have not
given my a number. This comes to 35M core hours in the coming year. With
contributions from CMU and a few of our smaller collaborators, we might get
to 50M this year. So that would be my range for the coming year, 35M - 50M.
Beyond that, we need to start planning now on how we are going to grow. But
it will be a challenge to ramp up from ~1Mhr over the past year to 40Mhr.
We will need to demonstrate our ability to effectively consume this much
simulation before looking for more resources.
