چکیده
The cost of high-performance parallel platforms prevents parallel processing techniques from spreading in present applications. Networks of Workstations (NOW) exploiting oo-the-shelf communication hardware, high-end PCs and standard communication software provide much cheaper but poorly performing parallel platforms. In our NOW prototype called GAMMA (Genoa Active Message MAchine) every node is a PC running a Linux operating system kernel enhanced with eecient communication mechanisms based on the Active Message paradigm. Active Messages supply virtualization of the network interface close enough to the raw hardware to guarantee good performance. The preliminary performance measures obtained by GAMMA show how competitive such a cheap NOW is.

Low latency IIR digital filter design by using metaheuristic optimization algorithms
Filters are particularly important class of LTI systems. Digital filters have great impact on modern signal processing due to their programmability, reusability, and capacity to reduce noise to a satisfactory level. From the past few decades, IIR digital filter design is an important research field. Design of an IIR digital filter with desired specifications leads to a no convex optimization pr...
متن کاملDesign of a Low-Latency Router Based on Virtual Output Queuing and Bypass Channels for Wireless Network-on-Chip
Wireless network-on-chip (WiNoC) is considered as a novel approach for designing future multi-core systems. In WiNoCs, wireless routers (WRs) utilize high-bandwidth wireless links to reduce the transmission delay between the long distance nodes. When the network traffic loads increase, a large number of packets will be sent into the wired and wireless links and can...
متن کاملImplementing a Low Cost, Low Latency Parallel Platform
The practical application of parallel processing techniques is in most cases hampered by the cost of high-performance parallel platforms. The use of a Network of Workstations (NOW) connected by a fast Local Area Network (LAN) is very appealing for implementing a low-cost parallel platform. The use of higher-end PCs connected by fast LAN and running Unix-like operating systems is even more appea...

By increasing, the complexity of chips and the need to integrating more components into a chip has made network –on- chip known as an important infrastructure for network communications on the system, and is a good alternative to traditional ways and using the bus. By increasing the density of chips, the possibility of failure in the chip network increases and providing correction and fault tol...
متن کاملA low-latency control plane for dense cellular networks
In order to keep up with the increasing demands for capacity, cellular networks are becoming increasingly dense and heterogeneous. Dense deployments are expected to provide a linear capacity scaling with the number of small cells deployed due to spatial reuse gains. However in practice network capacity is severely limited in dense networks due to interference. The primary reason is that the cur...
