News
----
- COVID-19 presence everywhere and office work nowhere is no news anymore
- Briank&Frank are fine with "Idea on discussions how jobs use caches", could be two-folding meeting, best to organize after other meetings settle this month, opening doodle or ask for the week after April 21 and see if Frank/Brian has time then. April 21 Ilija presents at DOMA/ACCESS meeting ATLAS update on VP tests ... Btw, here is last presentation from April 7th on "INFN caching activity update: reading NanoAODs through the cache":
