The organizers of the 21st International ACM Symposium on High-Performance Parallel and Distributed Computing (HPDC'12) call for proposals for workshops to be held with HPDC'12. Depending on the number of workshop proposals accepted, workshops will run on June 18-19 (Monday and Tuesday) or on June 19 (Tuesday), preceding the main conference on June 20-22.

Workshops should provide forums for discussion among researchers and practitioners on focused topics or emerging research areas. Organizers may structure workshops as they see fit, possibly including invited talks, panel discussions, presentations of work in progress, fully peer-reviewed papers, or some combination. Workshops could be scheduled for a half day or a full day, depending on interest, space constraints, and organizer preference. Organizers should design workshops for approximately 20-40 participants, to balance impact and effective discussion.

Workshop proposals must be sent to the HPDC'12 Workshops Chair, Alexandru Iosup, at a.iosup@tudelft.nl, and should include:

• The name and acronym of the workshop
• A description (0.5-1 page) of the theme of the workshop
• A description (one paragraph) of the relation between the theme of the workshop and of HPDC
• A list of topics of interest
• The names and affiliations of the workshop organizers, and if applicable, of a significant portion of the program committee
• Data about previous offerings of the workshop (if any), including the attendance, the numbers of papers or presentations submitted and accepted, and the links to the corresponding websites
• A publicity plan for attracting submissions and attendees

Due to publication deadlines, workshops must operate within roughly the following timeline: papers due mid February (2-3 weeks after the HPDC deadline), and selected and sent to the publisher by mid April.
