Speedup Versus Efficiency in Parallel Systems
Found in: IEEE Transactions on Computers
By D.L. Eager, J. Zahorjan, E.D. Lazowska
Issue Date:March 1989
pp. 408-423
The tradeoff between speedup and efficiency that is inherent to a software system is investigated. The extent to which this tradeoff is determined by the average parallelism of the software system, as contrasted with other, more detailed, characterizations...

Computer science: past, present, and future
Found in: Proceedings of the 39th SIGCSE technical symposium on Computer science education (SIGCSE '08)
By Ed Lazowska
Issue Date:March 2008
pp. 63-70
Computing research has made remarkable advances, but there's much more to be accomplished. The next few decades of advances should be even more significant, and even more interesting, than the past few. The National Science Foundation has created the Compu...
     
The expansion of CS4HS: an outreach program for high school teachers
Found in: Proceedings of the 39th SIGCSE technical symposium on Computer science education (SIGCSE '08)
By Ed Lazowska, Joe Wise, Lenore Blum, Thomas J. Cortina
Issue Date:March 2008
pp. 63-70
This paper describes CyberCivics, a novel approach to computer science outreach that integrates hands-on computing experiences with the study of contemporary social and political issues. We provide details of one such curriculum, focused on electronic voti...
     
The Effect of Scheduling Discipline on Spin Overhead in Shared Memory Parallel Systems
Found in: IEEE Transactions on Parallel and Distributed Systems
By J. Zahorjan, E.D. Lazowska, D.L. Eager
Issue Date:April 1991
pp. 180-198
<p>Spinning, or busy waiting, is commonly employed in parallel processors when threads ofexecution must wait for some event, such as synchronization with another thread.Because spinning is purely overhead, it is detrimental to both user response time...
 
Using Processor-Cache Affinity Information in Shared-Memory Multiprocessor Scheduling
Found in: IEEE Transactions on Parallel and Distributed Systems
By M.S. Squiillante, E.D. Lazowska
Issue Date:February 1993
pp. 131-143
<p>In a shared-memory multiprocessor system, it may be more efficient to schedule a taskon one processor than on another if relevant data already reside in a particularprocessor's cache. The effects of this type of processor affinity are examined. It...
 
Exploiting Lookahead in Parallel Simulation
Found in: IEEE Transactions on Parallel and Distributed Systems
By Y.B. Lin, E.D. Lazowska
Issue Date:October 1990
pp. 457-469
<p>Lookahead is the ability of a process to predict its future behavior. The feasibility of implicit lookahead for non-FCFS stochastic queuing systems is demonstrated. Several lookahead exploiting techniques are proposed for round-robin (RR) system s...
