A reconfigurable mesh (RM) is the two-dimensional mesh-connected computer enhanced with a reconfigurable bus system. The bus system is used to dynamically obtain various interconnection patterns among the processors during the execution of programs. ...

In this paper we present fine-grained multithreaded algorithms and implementations for the Fast Fourier Transform (FFT) problem. The FFT problem has been formulated using two distinct approaches based on the dataflow concepts. The first approach, ...

We conduct an experimental analysis of a distributed, randomized algorithm for edge coloring simple undirected graphs. The algorithm is extremely simple, yet, according to the probabilistic analysis, it computes nearly optimal colorings very quickly [12]...

Suppose that a parallel algorithm can include any number of parallel threads. Each thread can proceed without ever having to busy wait to another thread. A thread can proceed till its termination, but no new threads can be formed. What kind of problems ...

The computer industry is currently examining the use of strong synchronization operations such as double compare-and-swap (DCAS) as a means of supporting non-blocking synchronization on tomorrow's multiprocessor machines. However, before such a strong ...

In the last couple of years a dramatic growth of enterprise data storage capacity can be observed. As a result, new strategies have been sought that allow servers and storage being centralized to better manage the explosion of data and the overall cost ...

A hierarchical bus network T = (V, E) uses hierarchically, tree-like connected buses as a communication network. New communication technologies like SCI (Scalable Coherent Interface) (see, e.g., [6, 7]) make such networks very attractive, because they ...

In recent years, the task of allocating jobs to servers has been studied with the “balls and bins” abstraction. Results in this area exploit the large decrease in maximum load that can be achieved by allowing each job (ball) a little freedom in choosing ...

Random redundant allocation of data to parallel disk arrays can be exploited to achieve low access delays. New algorithms are proposed which improve the previously known shortest queue algorithm by systematically exploiting that scheduling decisions can ...

In this paper, we compare and contrast two techniques to improve capacity/conflict miss traffic in CC-NUMA DSM clusters. Page migration/replication optimizes read-write accesses to a page used by a single processor by migrating the page to that ...

Cohen et al. [5] recently initiated the theoretical study of connection caching in the world-wide web. They extensively studied uniform connection caching, where the establishment cost is uniform for all connections [5, 6]. They showed that ordinary ...

In this paper, we study the design of fault tolerant networks for arrays and meshes by adding redundant nodes and edges. For a target graph G (linear array or mesh in this paper), a graph G′ is called a κ-fault-tolerant graph of G if when we remove any ...

Motivated by Web applications, we recently introduced the following theoretical model for connection-caching: Each host on a network can maintain (cache) a limited number of connections to other hosts. A message can be transmitted from one host to ...

In this paper we consider communication issues arising in mobile networks that utilize Frequency Division Multiplexing (FDM) technology. In such networks, many users within the same geographical region can communicate simultaneously with other users of ...

Many parallel applications require periodic redistribution of workloads and associated data. In a distributed memory computer, this redistribution can be difficult if limited memory is available for receiving messages. We propose a model for optimizing ...

Up to now, diffusive load balancing schemes have only been developed for homogeneous networks. We generalize existing diffusion schemes, in order to deal with heterogeneous networks. In these networks, every processor can have arbitrary computing power, ...

We refine the model underlying our prior work on scheduling cycle-stealing opportunities in NOWs [5, 16], obtaining a model wherein the scheduling guidelines of [16] produce optimal schedules for every such opportunity. Although computing optimal ...

We study the problem of executing parallel programs, in particular Cilk programs, on a collection of processors of different speeds. We consider a model in which each processor maintains an estimate of its own speed, where communication between ...

This paper studies the data locality of the work-stealing scheduling algorithm on hardware-controlled shared-memory machines. We present lower and upper bounds on the number of cache misses using work stealing, and introduce a locality-guided work-...
