This paper investigates partitioning the ways of a shared last-level cache among the threads of a symmetric data-parallel application running on a chip-multiprocessor. Unlike prior work on way-partitioning for unrelated threads in a multiprogramming workload, the domain of multithreaded programs requires <i>both</i> throughput and fairness. Additionally,(More)
—This paper outlines our ongoing efforts to effectively integrate a parallel file system in a cloud environment. We investigate how a parallel file system (PFS) can be effectively integrated and provided as a service to cloud users running High Performance Computing (HPC) applications, and what would be the performance and security implications of such a(More)
Multithreaded programs are commonly written and optimized for homogeneous multi-core processors assuming equal performance from all the cores. This assumption greatly simplifies the partitioning and balancing of an application's workload across threads; however, it no longer holds when the frequencies of the cores differ due to within-die variations,(More)
Task-parallel programming models with input annotation-based concurrency extraction at runtime present a promising paradigm for programming multicore processors. Through management of dependencies, task assignments, and orchestration, these models markedly simplify the programming effort for parallelization while exposing higher levels of concurrency. In(More)
Device reliability and manufacturability have emerged as dominant concerns in end-of-road CMOS devices. An increasing number of hardware failures are attributed to manufacturability or reliability problems. Maintaining an acceptable manufacturing yield for chips containing tens of billions of transistors with wide variations in device parameters has been(More)
Capacitive crosstalk induced signal integrity effects have been studied for over a decade. A typical victim net has multiple aggressors. In worst-case analysis of crosstalk effects, it is customary to assume that (i) all aggressors can switch at the same time and (ii) aggressors themselves are not subject to other crosstalk effects. Further refinements of(More)
