Hi Mark, Curtis, David, you probably don’t remember the attached email from a year and a bit ago but it was sent by Mark and is the one that the GLUEX part of my computing requirements spreadsheet is based on. There was an earlier “computing model details” spreadsheet from 2012 that had 30 PAC days in phase I, 60 in Phase II and 60 in Phase III. As you can imagine the dates and numbers make little sense any more. If Phase I was the run that we just had plus the one in Spring then 30 PAC days is equal to 60 days running and, counting days gone plus days expected I can’t see how you are going to get that in total. Phase II certainly isn’t going to start on May 14th since May 4th is when the accelerator will be shut down for the summer. That then begs the question of where phase III starts and what form it takes. Is Phase II just shifted to 2016 or do we spring directly from I to III with II dropped? With the review coming up these dates and numbers are clearly indefensible. With no Phase II starting in May there is no need to do anything more with the farm in FY15 since we are now almost at the equivalent of 5000 cores which is more than the 500 in the requirement (remember that these were normalized relative to “2013 model" Sandy Bridge processors). For various reasons CLAS12 has almost completely dropped out of the near term picture. The driver for a late FY15 and/or early FY16 bulk purchase of nodes is now what the GLUEX schedule is after October 1st 2015. Can you come up with an “official GLUEX” statement of what you expect so that I can update my spreadsheets etc. Regards to all, Graham > Begin forwarded message: > > Date: October 23, 2013 at 4:49:13 pm EDT > From: Mark Ito > To: Heyes Graham > Cc: Lawrence David > Subject: Re: Software review and computing requirements. > > Graham, > > Quick answer: > > Run Period > Date > Number of Cores > Phase I > 11-Oct-2014 > 500 > Phase II > 14-May-2015 > 5,000 > Phase III > 12-Feb-2016 > 10,000 > > I reserve the right to twiddle later. > > -- Mark
