Empirical Development of a Heuristic Evaluation Methodology for Shared Workspace Groupware
, 2002
"... Good real time groupware products are hard to develop, in part because evaluating their support for the basic activities of teamwork is difficult and costly. To address this problem, we are developing discount evaluation methods that look for groupware-specific usability problems. In a previous pape ..."

paper, we detailed a new set of usability heuristics that evaluators can use to inspect shared workspace groupware to see how they support for teamwork. We wanted to determine whether the new heuristics could be integrated into a low-cost methodology that parallels Nielsen’s traditional heuristic

Difference Engine: Harnessing Memory Redundancy in Virtual Machines
"... Virtual machine monitors (VMMs) are a popular platform for Internet hosting centers and cloud-based compute services. By multiplexing hardware resources among virtual machines (VMs) running commodity operating systems, VMMs decrease both the capital outlay and management overhead of hosting centers. ..."

that content-based page sharing provides modest decreases in the memory footprint of VMs running similar operating systems and applications. Our studies show that significant additional gains can be had by leveraging both sub-page level sharing (through page patching) and in-core memory compression. We build
Architectural Support for Scalable Speculative Parallelization
- in SharedMemory Systems”, in Proc. of the 27th Int. Symp. on Computer Architecture, 2000
"... Speculative parallelization aggressively executes in parallel codes that cannot be fully parallelized by the compiler. Past proposals of hardware schemes have mostly focused on single-chip multiprocessors (CMPs), whose effectiveness is necessarily limited by their small size. Very few schemes have a ..."

attempted this technique in the context of scalable shared-memory systems. In this paper, we present and evaluate a new hardware scheme for scalable speculative parallelization. This design needs relatively simple hardware and is efficiently integrated into a cache-coherent NUMA system. We have designed
Locksmith: context-sensitive correlation analysis for race detection
- In PLDI ’06: Proceedings of the 2006 ACM SIGPLAN conference on Programming language design and implementation
, 2006
"... One common technique for preventing data races in multi-threaded programs is to ensure that all accesses to shared locations are consistently protected by a lock. We present a tool called Locksmith for detecting data races in C programs by looking for violations of this pattern. We call the relation ..."

Kendo: Efficient Deterministic Multithreading in Software
- In ASPLOS
, 2009
"... Although chip-multiprocessors have become the industry standard, developing parallel applications that target them remains a daunting task. Non-determinism, inherent in threaded applications, causes significant challenges for par-allel programmers by hindering their ability to create parallel applic ..."

an inter-leaving of shared data accesses that is both deterministic and provides good load balancing. Kendo can run on to-day’s commodity hardware while incurring only a modest performance cost. Experimental results on the SPLASH-2 applications yield a geometric mean overhead of only 16% when running on 4
How fair are group assignments? A survey of students and faculty and a modest proposal
- Journal of Information Technology Education
, 2003
"... Group assignments are becoming increasingly popular in education. While some academics would admit that they lessen their workload, many would say group assignments give students the “real world ” group experience needed for later employment. Problems with group assignments have been noted in the li ..."

frequently encountering problems. Reasons for the discrepancy are considered. The perceived benefits and negative aspects of group assignments were also considered. The students seem to put more store on sharing ideas and social interaction than staff and they are concerned about timetabling and logistical
Costs and Benefits of Load Sharing in the

, 2004
"... We present an analysis of the costs and benefits of load sharing of parallel jobs in the computational grid. We begin with a workload generation model that captures the essential properties of parallel jobs and use it as input to a grid simulation model. Our experiments are performed for both homoge ..."

slowdown for lightly-loaded machines in a heterogeneous grid. With respect to the number of sites in a grid, we find that the benefits obtained by load sharing do not scale well. Small to modest-size grids can employ load sharing as effectively as largescale grids. We also present and evaluate an effective
Job Declines in New York–New Jersey Region to Slow in 2003; Modest Growth Seen for 2004
, 2003
"... Employment in the New York–New Jersey region will decline in 2003—but only slightly— and the region’s economy is poised to rebound in 2004 with 1 percent growth, or a gain of 128,000 jobs. Continued expansion in the national economy and sustained vigor in the financial markets, however, will be esse ..."
