The software week goal is to facilitate communication and collaboration between everyone as we move forward extended support for Fermi. FSSC members will be available at SLAC all week for group discussions and one-on-one meetings. In addition to targeted topics, we encourage attendees with broad or cross-cutting interests to join the various discussions. There will be plenty of work, so we'll need everyone to take part in this transition.

Previous Software Weeks:  Winter 2017, Fall 2017 , Winter 2018

Dates: March 2, 2020 - March 5, 2020

Schedule and Agenda

All times Pacific Standard.

One conference room is schedule each day and the other is open for breakout sessions, side meetings, or whatever else might be needed.  There is a lot of time for lunch, too, so we can use some of that time, if needed. 

The is a draft schedule.  Hopefully, it captures all the sessions/topics we will need. Things will probably need to be moved around to accommodate people's schedules or due to discussion at sessions, i.e., pick up something later or work on something that came up, further discuss ideas that come up. 

Friday has been left open in case we need it, and Joe, Alex, Tom, and Don will be around that day.

We can discuss scheduling changes on the #softwareweek channel.
