In last January’s Manager column, “Fear of Trying: The Plight of the Rookie Project Manager,” Roger Pressman asked a question critical to the future of our profession: “So, how do we grow a good project manager? What do we teach the rookie who has just been appointed to lead her first software project?” Instead of answering this question directly, Pressman focused his article on four key skills...

The necessity of interoperability among Petri net tools has led to the development of the PNML (Petri Net Markup Language) standard. By adopting PNML, tools mainly concentrated on modeling activities should generate PNML files to be analyzed by analysis-specific Petri net tools. In this context, we propose an extension to the PNML based on MOF (Meta Object Facility). The implementation of the M...

Organizing a medical facility efficiently is hard due to the numerous patient trajectories and their use of joint and scarce resources. Moreover, these trajectories tend to be complex and characterized by uncertain medical processes. In this paper, we will structure patient trajectories using clinical pathways and aggregate them in a discrete-event simulation model. This model enables the healt...

Developing a distributed debugger is much more complex than developing a sequential debugger. This added complexity is mainly due to the non-determinism of events that communication delays introduce into distributed systems. We explore the problems that one must address when designing a distributed program debugger and then describe our design and implementation of DPD (distributed program debu...

A convenient and uniform interface to metadata is an important facility for any database system, not only from the point of view of the user or system manager but also for the application developer writing front-ends and query optimisers etc. If this interface can take the same form as that to the ordinary data, so much the better. This report describes an implementation of just such an interfa...

EMWF (Embedded Workflow Framework) is an open source middleware for flexible (i.e., configurable, customizable and adaptable), usercentric automation and assistive devices and systems. EMWF 1.0 provides a light-weight workflow manager and engines on Windows CE, Windows XP Embedded, and Linux. It is for small embedded automation devices. EMWF 2.0 also provides basic message passing and real-time...

H.M. Gladney (B.A., Toronto, 1960; Ph.D., Princeton, 1963) has been an ACM Member since 1985 and a Fellow of the American Physical Society since 1975. As an IBM Research Staff Member from 1963 to 2000, he led the architecture and pilot work for three projects that quickly led to hugely successful products: IBM Resource Access Control Facility, IBM Event Driven Executive, and IBM Digital Library...

In this paper, we introduce Systematic P2P Aided Cache Enhancement or SPACE, a new collaboration scheme among clients in a computer cluster of a high performance computing facility to share their caches with each other. The collaboration is achieved in a distributed manner, and is designed based on peerto-peer computing model. The objective is to provide (1) a decentralized solution, and (2) a ...
