In this paper we present JavaPSL, a Performance Specification Language that can be used for a systematic and portable specification of large classes of experiment-related data and performance properties for distributed and parallel programs. Performance properties are described in a generic and normalized way, thus interpretation and comparison of performance properties is largely alleviated. Moreover, JavaPSL provides meta-properties in order to describe new properties based on existing ones and to relate properties to each other.

The PETSc (Portable Extensible Tools for Scientific computing) library arose from research into domain decomposition methods which require combining many different solutions in a single application. The initial efforts tried to use existing numerical software but had limited success. The problems include everything from faulty assumptions about the computing environment (e.g., how many processes there are) to implicit (yet deadly) global state. More recently, PETSc and PVODE have found a way to cooperate, and new techniques that exploit dynamically linked libraries offer a more general approach to interoperable components. The paper highlights some of the issues in building sharable component software and discussing mistakes still often made in designing, maintaining, documenting, and testing components.

Researchers from many different areas have demands for computational power to solve their specific problems. Today, many are successfully using implementations of MPI, a standard message passing interface, on parallel and distributed environments to satisfy their computational requirement. In general, checkpointing a parallel/distributed program is more complex than checkpointing a sequential program. Checkpointing provides the backbone for rollback recovery (fault-tolerance), playback debugging, process migration and job swapping. This work proposes to investigate techniques to design, develop, and implement a checkpointing system for symmetric multiprocessors environments, named SMPCkpt. The goal is to develop an integrated checkpointing system for MPI-based applications on Sun Enterprise 10000. The system will support a range of facilities, including fork, compressed checkpointing and transparent checkpointing facilities, and the abilities of
