Hello, As promised at TechAssessWG telecon, here is the updated spreadsheet with CPU requirements for query load broken down per year:
http://www.slac.stanford.edu/~becla/tmp/lsst_diskIO_estimates_v15.xls (see perDRStats page) I also added number of disks and memory per DR. The numbers are: DR Year CPU Disks RAM 1 5,329 3,932 19 2 2013 10,468 9,090 47 4 2014 16,077 16,234 90 6 2015 21,887 23,810 136 8 2016 27,897 31,725 184 10 2017 34,083 39,917 234 12 2018 40,424 48,345 286 14 2019 46,905 56,979 338 16 2020 53,513 65,797 392 18 2021 60,236 74,781 447 20 2022 67,066 83,918 502 As before, 1 CPU = AMD Opteron 1.8GHz Note a relatively big jump between DR1 and DR2, it is triggered by a jump in number of Sources in the Source table. As discussed this might get offset by the fact that the first year is for commissioning and we will not store as much data as during 'regular' production.
