Exploiting Set-Level Non-Uniformity Of Capacity Demand To Enhance Cmp Cooperative Caching, Dongyuan Zhan, Hong Jiang, Sharad C. Seth Sep 2009

Exploiting Set-Level Non-Uniformity Of Capacity Demand To Enhance Cmp Cooperative Caching, Dongyuan Zhan, Hong Jiang, Sharad C. Seth

School of Computing: Technical Reports

As the Memory Wall remains a bottleneck for Chip Multiprocessors (CMP), the effective management of CMP last level caches becomes of paramount importance in minimizing expensive off-chip memory accesses. For the CMPs with private last level caches, Cooperative Caching (CC) has been proposed to enable capacity sharing among private caches by spilling an evicted block from one cache to another. But this eviction-driven CC does not necessarily promote cache performance since it implicitly favors the applications full of block evictions regardless of their real capacity demand. The recent Dynamic Spill-Receive (DSR) paradigm improves cooperative caching by prioritizing applications with higher …

Where Does Your Institution Stand?, Wendell Brase, Mark Askren Mar 2009

Where Does Your Institution Stand?, Wendell Brase, Mark Askren

Information Technology Services: Publications

Media coverage of sustainability and "green" issues is hard to ignore these days. But less clear is a specific understanding of what this agenda means within higher ed IT organizations. For starters, it's useful to self-assess whether your campus is a leading innovator on all things "green" or satisfied to remain inconspicuous in the middle of the pack. If your institution is trailing but wants to assert a leadership role in environmental stewardship, you need to get engaged to understand what it will take to catch up and how IT can be a leader, not just a contributor, to such …

Translucent Optical Wdm Networks For The Next-Generation Backbone Networks, Byrav Ramamurthy, Srinath Yaragorla, Xi Yang Jan 2001

Translucent Optical Wdm Networks For The Next-Generation Backbone Networks, Byrav Ramamurthy, Srinath Yaragorla, Xi Yang

School of Computing: Conference and Workshop Papers

This paper proposes an alternate approach to fully transparent and fully opaque optical networks for operating a wavelength routed optical network. In this paper, the architecture of the regeneration node that performs sparse regeneration (or translucency) is discussed. The regeneration demands generated from call blocking and signal quality requirements are addressed. Two implementation strategies for incorporating sparse regeneration are introduced and their relative merits are studied.

An Organizational Learning Approach To Domain Analysis, Scott Henninger, Kris Lappala, Anand Raghavendran Jan 1995

An Organizational Learning Approach To Domain Analysis, Scott Henninger, Kris Lappala, Anand Raghavendran

School of Computing: Conference and Workshop Papers

As the application of computer technology continues to proliferate and diversify, the identification and understanding of application domains is becoming increasingly important to software development methodologies. Domain analysis techniques have been developed to accumulate and formalize the knowledge necessary for successful software reuse. These techniques have been shown to be useful, but suffer from defining the domain too restrictively, burying important relationships deep in domain taxonomies, and prohibiting flexible identification of domains with common issues. Techniques are needed that dynamically detect recurring patterns of activities in development projects. This paper presents a method for developing and refining the knowledge and …
