To deal with the complexity of software development, abstractions such as macros, functions, abstract data types, and objects are commonly employed by sequential as well as parallel programming models. This paper describes the concept of a design pattern for the development of parallel applications. A design pattern in our case describes a recurring parallel programming problem and a reusable solution to that problem. A design pattern is implemented as a reusable code skeleton for quick and reliable development of parallel applications. A parallel programming system, called DPnDP (Design Patterns and Distributed Processes), that employs such design patterns is described. In the past, parallel programming systems have allowed fast prototyping of parallel applications based on commonly occurring communication and synchronization structures. The uniqueness of our approach is in the use of a standard structure and interface for a design pattern. This has several important implications: first, design patterns can be defined and added to the system's library in an incremental manner without requiring any major modification of the system (extensibility). Second, customization of a parallel application is possible by mixing design patterns with low level parallel code resulting in a flexible and efficient parallel programming tool (flexibility). Also, a parallel design pattern can be parameterized to provide some variations in terms of structure and behavior.","PeriodicalId":243171,"journal":{"name":"Proceedings.

A Web browser running on the user's machine provides a user-friendly interface to server-site user accounts and allows the use of parallel computing platforms and software in a convenient manner. The user may create, edit, and execute files through this Web browser interface. This new Web-based client-server architecture has the potential of being used as a future front-end to high-performance computer systems. We discuss the design and implementation of several prototype WPPEs that are currently in use at the Northeast Parallel Architectures Center and the Cornell Theory Center. These initial prototypes support high-level parallel programming with Fortran 90 and High Performance Fortran (HPF), as well as explicit low-level programming with Message Passing Interface (MPI). We detail the lessons learned during the development process and outline the tradeoffs of various design choices in the realization of the design. We especially concentrate on providing server-site user accounts, mechanisms to access those accounts through the Web, and the Web-related system security issues.","PeriodicalId":243171,"journal":{"name":"Proceedings.

Even a moderately long run of five minutes can incur aggravating delays. To address this problem, techniques exist that allow re-executing a distributed program from intermediate points by using combinations of checkpointing and message logging. In this paper we explore another idea: how to support replay without logging the contents of any message. When no messages are logged, the set of global states from which replay is possible is constrained, and it has been unknown how to compute this set without exhaustively searching the space of all global states, whose size is exponential in the number of processes. We present a simple and efficient hybrid on-the-fly/post-mortem algorithm for detecting the necessary and sufficient conditions under which parts of the execution can be replayed without message logs. A small amount of trace (two vectors) is recorded at each checkpoint and a fast post-mortem algorithm computes global states from which replay can begin. This algorithm is independent of the checkpointing technique used.","PeriodicalId":243171,"journal":{"name":"Proceedings.

VDCE delivers well-defined library functions that relieve end-users of tedious task implementations and also support reusability. In this paper we present the conceptual design of VDCE software architecture, which is defined in three modules: (a) the Application Editor, a user-friendly application development environment that generates the Application Flow Graph (AFG) of an application; (b) the Application Scheduler, which provides an efficient task-to-resource mapping of AFG; and (c) the VDCE Runtime System, which is responsible for running and managing application execution and monitoring the VDCE resources.","PeriodicalId":243171,"journal":{"name":"Proceedings.
