NMR-MPar: A Fault-Tolerance Approach for Multi-Core and Many-Core Processors

Parallel Packet Processing on Multi-core and Many- core Processors

The Service-oriented Router (SoR), a highly functional router based on a novel router architecture, enables unprecedented web services traditional routers were unable to provide. The SoR performs Deep Packet Inspection (DPI) to analyze Layer 7 information, which is becoming increasingly difficult due to the substantial increase in Internet traffic. Meanwhile, multi-core processors and general-p...

Core Power Management Issues in Asymmectric Multi/Many-Core Processors

Power managing is a major issue in designing the future asymmectric multi/many-core processors. The challenge is to provide a solution that has low power consumption, in addition to trade off a small decrease in performance and throughput. Our design includes asymmetric cores in consideration of different points in the view of power-performance efficiency during an application’s execution. In t...

Fault Tolerance in Multi-Core Systems

Modern processors provide multiple cores for parallel computing. This paper describes how parallel processing on multiple cores can provide efficient fault tolerance. In general, multi-core processors provide structural redundancy which can be exploited for efficient replication. Furthermore, hardware features can improve performance of redundant execution by exchanging information between repl...

Parallel space saving on multi- and many-core processors

Given an array A of n elements and a value 2 ≤ k ≤ n, a frequent item or k-majority element is an element occurring in A more than n/k times. The k-majority problem requires finding all of the k-majority elements. In this paper we deal with parallel shared-memory algorithms for frequent items; we present a sharedmemory version of the Space Saving algorithm and we study its behavior with regard ...
