For technological reasons, in a realistic parallel computer the processors have to communicate via a communication network with bounded degree. Thus the question for a \good" communication network comes up. In this paper we present such a network, a universal parallel computer (UPC) with the following properties: (i) It has optimal time-loss, namely O(log c) for simulating networks of degree c....

Network bandwidth and packet processing needs are growing faster than processor speed. Even with the doubling of processing power every eighteen months, next generation network systems will require between one and two orders of magnitude more processors than today’s systems. They must rely on scalable, parallel and distributed architectures both in hardware and software. Because the traditional...

We introduce a task model for embedded systems operating on packet streams, such as network processors. This model along with a calculus meant for reasoning about packet streams allows a unified treatment of several problems arising in the network packet processing domain such as packet scheduling, task scheduling and architecture/algorithm explorations in the design of network processors. The ...

The exponential growth in Internet traffic has motivated the development of a new breed of microprocessors called Network Processors, which are designed to address the performance problem resulting from exploding Internet traffic. The development efforts of these network processors concentrate almost exclusively on streamlining their data-paths to speed up network packet processing, which mainl...

The chlorophyll-a (Chla) products of seven processors developed for the Medium Resolution Imaging Spectrometer (MERIS) sensor were evaluated. The seven processors, based on a neural network and band height, were assessed over an optically complex water body with Chla concentrations of 8.10–187.40 mg·m−3 using 10-year MERIS archival data. These processors were adopted for the Ocean and Land Colo...

Modern networks require the flexibility to support new protocols and network services without changes in the underlying hardware. Routers with general-purpose processors can perform data path packet processing using software that is dynamically distributed. However, custom processing of packets at link speeds on a high performance router requires immense computational power. Single workstation ...

Parallel processing is based on utilizing a group of processors to efficiently solve large problems faster than is possible on a single processor. To accomplish this, the processors must communicate and coordinate with each other through some type of network. However, the only function that most networks support is message routing. Consequently, functions that involve data from a group of proce...

In this paper, we propose an efficient design of a heterogeneous mesh router, using network processors. Wireless Mesh Network (WMN) is a multi-hop wireless network, comprising two kinds of nodes-mesh routers and mesh clients. Microsoft Research has developed Mesh Connectivity Layer (MCL) for computers that use Windows operating systems. In MCL routing is done using a protocol called Link Qualit...

The exponential growth in Internet popularity motivates network router and switch designers to develop custom software/hardware that can move packets through the network faster. Recently, a new breed of microprocessors called Internet processors have come into existence speciically to address the performance problem due to exploding In-ternet traac. The development eeorts of these Internet proc...
