Computing Community Consortium Blog

The goal of the Computing Community Consortium (CCC) is to catalyze the computing research community to debate longer range, more audacious research challenges; to build consensus around research visions; to evolve the most promising visions toward clearly defined initiatives; and to work with the funding organizations to move challenges and visions toward funding initiatives. The purpose of this blog is to provide a more immediate, online mechanism for dissemination of visioning concepts and community discussion/debate about them.

CCC Council Member Mark Hill to Deliver Distinguished Lecture at NSF

markhill2006-mediumOn Wednesday, December 18, 2013 at 10 am EST, Computing Community Consortium (CCC) Council Member Mark Hill will be delivering a Distinguished Lecture at the National Science Foundation (NSF).  Hill is the Gene M. Amdahl Professor of Computer Sciences and Electrical and Computer Engineering at the University of Wisconsin- Madison.

Hill’s talk will have two parts.  First, he will discuss possible directions for computer architecture research, including architecture as infrastructure, energy first, impact of new technologies, and cross-layer opportunities. This is based on a 2012 CCC whitepaper effort led by Hill. In the second part, Hill will discuss an example of the cross-layer research advocated in the first part. From the abstract:

Analysis shows that many “big-memory” server workloads, such as databases, in-memory caches, and graph analytics, pay a high cost for page-based virtual memory: up to 50% of execution time wasted. Via small changes to the operating system (Linux) and hardware (x86-64 MMU), this work reduces execution time these workloads waste to less than 0.5%. The key idea is to map part of a process’s linear virtual address space with a new incarnation of segmentation, while providing compatibility by mapping the rest of the virtual address space with paging.

The talk will be webcast live.  Please register for the webinar here by 11:59 PM EST, December 17.
