Presenters who wish to have hardware demonstrations are encouraged to mark their preference for a poster display. Accepted extended abstracts will be displayed as posters. All paper and extended abstract submissions need to use the approved IEEE templates.. Full paper submissions with the highest peer review ratings will be published by IEEE in the official HPEC proceedings available on IEEE eXplore. All other accepted submissions and extended abstracts are published on ieee-hpec.org. Vendors are encouraged to sign up for vendor booths. This will allow vendors to present their HPEC technologies in an interactive atmosphere suitable for product demonstration and promotion. Papers can be declared “student paper” if the first author was a student when doing the presented work, and will be eligible for the “IEEE HPEC best student paper award.” Papers should not be anonymized. We welcome input (firstname.lastname@example.org) on tutorials, invited talks, special sessions, peer reviewed presentations, and vendor demos.
