The Importance of Performance-Oriented Flexibility in System Software for Large-Scale Shared-Memory Multiprocessors

چکیده
There has been a growing interest in large-scale sharedmemory multiprocessors that support a wide range of application workloads. The architectural trend of such systems has been towards a distributed architecture, where processors, memory modules, and I/O modules are distributed throughout the machine, connected by some form of interconnect (rings, meshes, trees). Examples include the Stanford DASH [10] and FLASH [9], Massachusetts Institute of Technology Alewife [2], University of Toronto Hector [15], and Kendall Square Research KSR-1 [3] multiprocessors. In this type of architecture, commonly referred to as a Non-Uniform Memory Access time (NUMA) system, managing the locality between various resources is key to obtaining good performance.

Despite the fact that large scale shared-memory multiprocessors have been commercially available for several years, system software that fully utilizes all of their features is still not available. These machines require system software that is scalable, supports fault containment, and provides scalable resource management. Software supporting these features is currently unavailable, mostly due...
متن کاملHFS : A flexible file system for shared - memory multiprocessors
The HURRICANE File System (HFS) is designed for large-scale, shared-memory multiprocessors. Its architecture is based on the principle that a file system must support a wide variety of file structures, file system policies and I/O interfaces to maximize performance for a wide variety of applications. HFS uses a novel, object-oriented building-block approach to provide the flexibility needed to ...
متن کاملA Quantitative Analysis of the Performance and Scalability of Distributed Shared Memory
cache coherence protocols have become the key technology for creating moderate to large-scale shared-memory multiprocessors. Although the performance of such multiprocessors depends critically on the performance of the cache coherence protocol, little comparative performance data is available. Existing commercial implementations use a variety of different protocols including bit-vector/coarse-v...
متن کاملSimulation-based Performability Evaluation of Fault-tolerant Multiprocessors
We present a case study of performance and dependability evaluation of fault-tolerant multiprocessors. A distributed shared-memory multiprocessor architecture providing faulttolerance is analyzed taking into account system functionalities, actual workloads, failures of system components as well as the inter-component dependences. Since the evaluation of such a complex system has to be performed...
