This is a followup of the HEP software collaboration initial workshop that took place at CERN in April. The main goal of thi workshop is to refine the next steps for building the HEP Software Foundation (HSF) that is being organized to facilitate coordination and common efforts in high energy physics (HEP) software and computing internationally.

As you see from the timetable, much time is reserved for community input. Please sign up to present your input as an individual, project, experiment, etc. Abstract submission is now open. Please submit your proposals before January 19th 2015 using the link on the left side box on the indico main page.

The event page on the HSF website for this workshop is here.

SLAC's web page for the meeting with information on registration, attendees, local logistics etc. is here.

If you plan to participate remotely please add your name to this doodle poll.
