Get more NERSC allocation to complete DC1, and do DC2 #42

Closed richardxdubois closed 3 years ago

Due to ignorance (not realizing we had to ask for NERSC-hrs in our allocation request, not CPU-hrs, we lost a factor 2.5 off the bat. Then PhoSim-threaded has been 40% efficient. So, the ~3M hr estimate for DC1 has become more like 18M NERSC-hrs; we got 14M.

Lali has granted us two shots of 5M hrs in the past two weeks, so we should be able to finish DC1.

DC2 was estimated at 20M CPU-hrs. If PhoSim 3.7 is fully efficient, then we need ~50M NERSC-hrs for it. We're told we'll need to use KNL to get such a bump. So we need to learn what PhoSim's performance on KNL is.

We may also need to know ImSim's, if DC2 needs to be done with ImSim, and we'd need to use KNL.

There are issues open for both of these.

DC1 and DC2 processing is currently completed
