Meeting Notes for 24 Feb 2010

Misc

• Matt Bellis (on SLAC's BaBar) came to meet with us on the 23rd.
  • Discussed various visualization tools
  • Four-vectors to teach particle physics
  • his home page
• Database schema needs some work (primary/foreign key relationships, constraints, corrupted data)
• File layout is iffy (what if a research group moves schools? teacher moves school?)

Server

• IBM is getting data2 back into proper shape (replacement backplane, replacement 750GB HD)
• Argonne MCS has very kindly provided temporary space while our data server had downtime.
• The Argonne MCS Futures Lab has graciously donated an old data server (nietzsche) to us. Parts are en route.
• Upshot: data1 will have a 3.75TB RAID-5 array (6x750GB) and nietzsche will have a 8TB RAID-6 array (6x2TB).
  • Cosmic data will stay on data1
  • CMS and LIGO data will be on nietzsche
• Future Growth: We'll have six drive bays remaining (we'll need a controller card to drive them) if we need more storage

Cosmic

• Blessing meeting last week, see the notes.

LIGO

• In progress
• The ability to see an entire year's worth of data is super-nifty
• Weird bias changes in the data become apparent (known to LIGO)
• Workshops on 6 March and 27 March (homeschool students)
  • Technical staff aims to get a rough prototype done by the 6th for Tom to show and something usable by the 27th.

CMS

• LOs and milestones have feedback from Jean
