Imprecise Exceptions in Distributed Parallel Components Single Program Multiple Data (SPMD) components. The particular domain this design is intended for is high performance computing, which requires maximum resource use and efficiency. A performance-centric way to handle exceptions is explained as well as additional methodology to enforce exception strictness if required.

Impact of Cache Coherence Models on Performance of OpenMP Applicationsnd general ways to support the cache design in shared memory systems. The study is based on a simulation environment capable of modeling the parallel execution of OpenMP programs. First experimental results show that relaxed models are scalable and can be used as efficient alternative for those hardware coherence mechanisms.

Profiling and Tracing OpenMP Applications with POMP Based Monitoring Libraries exemplify the use of these libraries with performance measurement and visualization of the . s. benchmark code. Our examples show that the information provided by both tools is consistent, and provides data that is helpful for users to understand the source of performance problems.

Efficient Pattern Search in Large Traces Through Successive Refinementching attempts as well as in replicated code. This article describes an optimized design taking advantage of specialization relationships and leading to a significant runtime improvement as well as to more compact pattern specifications.

DRAC: Adaptive Control System with Hardware Performance Countersl system, observes the access requests on the memory bus. It then adapts its user-level scheduling strategy to maximize the resource utilization. We describe the DRAC system and its mathematical model. We show experimental results that prove the DRAC system is nearly optimal with our model.
