THIS WILL BE A VIRTUAL MEETING IN JUNE 2020

Due to recent COVID-19 challenges, the PowerStack committee plans on organizing its annual mid-year seminar as a digital event instead of face-to-face. This structure has the additional benefit of including participants who have been unable to attend prior events due to travel restrictions. Like past years, we will schedule this event during the week prior to the ISC conference (which is also going digital).

The PowerStack seminar will be June 17th (Wed) through June 19th (Fri) with the exact time to be decided soon (we plan on 3 hour blocks on each day). We are quite hopeful that this will lead to more focused discussions. The goal is provide updates from the working groups that had formed at the last seminar in November and to discuss the resulting documents and their next steps. Attendance will be free of charge. Registration link below

Please feel free to forward the news of our digital seminar to other colleagues, as needed.

Sincerely,
The HPC PowerStack core-committee

PowerStack Seminar

June 17-19, 2020 (Wed-Fri)
Virtual Event

The seminar on “The HPC PowerStack: Enabling Efficient Power Management in High-Performance Computing through Hierarchical Design” will be held digitially in June 2020. It will bring together experts from academia, research laboratories and industry in order to design and engineer a holistic and extensible, deployable power management framework. Such a framework could ultimately lead to standardization or - at least - homogenization efforts for this important piece of the HPC software stack.

If you are interested in attending, please let one of the organizers know.
