Hello all, Thanks Jacek!
I have updated the LSST CPU Needs spreadsheet (document-2116) with the new CPU numbers and the corresponding slide in the proposal presentation (document-2082). Cristina and Arun, please adjust the AC and DAC cost estimates accordingly for the latest CPU and disk requirements NLT Tuesday next week. Thanks!
