The Communities Program seeks to attract, train, and encourage tomorrow's high performance computing professionals. SC12 encourages students, researchers and faculty from among underrepresented communities, educators, early-career students, professionals, and international groups to participate in the SC conference through one or more of the following programs: Broader Engagement, Educators Program, Student Cluster Competition, Doctoral Showcase, International Ambassadors and Student Volunteers, as well as other special programs being planned, such as the Student Job Fair, George Michael Memorial Ph.D. Fellowship, and the Mentoring Program. This year, we will be continuing efforts from previous SC conferences to increase interactions and synergy with the Technical Program via invited speakers, enabling access to Tutorials, etc. Limited support is available for Communities programs. Please refer to the associated Communities webpages for information on how to apply and participate.
