Real-time System Scheduling and Information Theory: From Uniprocessors to Multiprocessors
Since Claude Shannon presented the definition of information and entropy in 1948, different science fields have used this theoretical background to represent the uncertainty of a system. For real-time systems, task scheduling is one of the most studied topics due to the constraint that all the …

Constructing and evaluating weak memory models
… of implementing optimizations that are used in uniprocessors, while building a shared-memory multiprocessor. Commercial weak memory models like ARM and POWER are extremely complicated: it has taken over a decade to formalize their definitions. These formalization efforts are mostly …

Measurement-Based Performance Models of Numerical Problems on Loosely-Coupled Systems
… of significant performance improvements over uniprocessors. Performance evaluation is necessary to effectively utilize these systems and to uncover and remove performance bottlenecks, which prevent the realization of their performance potential. Multiprocessors fall into one of two categories: …

Improving Multicore Resource Efficiency and Performance
… last few years and multi-cores having replaced uniprocessors, software development must now turn towards shared memory parallel programming to continue enhancing performance. Shared memory parallel programming; however is significantly more challenging than its sequential counterpart. …

A class library approach to concurrent object-oriented programming with applications to VLSI CAD
… medium-grain parallelism. The interface supports uniprocessors, shared memory multiprocessors, distributed memory multicomputers, and hybrid architectures comprising network-connected clusters of uni- and multiprocessors. The library currently supports workstations from Sun, shared memory …

Prefetching Vs The Memory System : Optimizations for Multi-core Server Platforms
… accurate when applied to simple systems (e.g. uniprocessors), but they become increasingly inaccurate as the level of complexity of the system grows -- as cores are added, and as prefetching is added. Memory side prefetching. We then perform a detailed case study of a well known server oriented …

SC²EPTON : high-performance and scalable, low-power and intelligent, ordered Mesh on-chip network
… and voltage scaling led to a shift from uniprocessors to multicore processors, to the point where the on-chip interconnect plays a larger role in achieving the desired performance and power goals. Shared memory multicores are subject to data sharing concerns as each processor computes on …
