Non-blocking networks have many applications in communications. Typical examples are telephone switching networks and communication networks among processors or between processors and memory devices. We construct non-...

parallel randomized algorithms are presented that solve n-dimensional systems of linear equations and compute inverses of n × n non-singular matrices over a field in O((log n)2) time, where each time unit represe...

A perfect hash function for a (multi)set X of n integers is an infective function h : X → {1,., s}, where s = O(n), that can be stored in O(n) space and evaluated in constant time by a single processor. We show that ...

A collection of local workpiles (task queues) and a simple load balancing scheme is well suited for scheduling tasks in shared memory parallel machines. Task scheduling on such machines has usually been done through a...

We present a number of efficient parallelalgorithms for constructing 2- and 3-dimensional convex hulls on a randomized CRCW PRAM. Specifically, we show how to build the convex hull of n pre-sorted points in the plane...

We present several algorithms for sorting efficiently with parallel two-level and multilevel memories. Our main result is an elegant, easy-to-implement, optimal, deterministic algorithm for external sorting with P dis...

The problem of packet routing on an r-dimensional mesh-connected array or grid of processors with side-length n is studied. Each processor is able to store rf(n) packets, f(n) 1-1/r. The new class of balanced routing ...

The contributions of this paper are twofold. First, we outline criteria by which any model of asynchronous shared memory parallel computation can be judged. Previous models are considered with respect to these factors. Next, we introduce a new model, and show that this model fulfils all the listed requirements. We also analyze in our model the complexity of several fundamental parallelalgorithms.
In this paper we give efficient parallelalgorithms for a number of problems from computational geometry by using generalized versions of parallel plane sweeping. We illustrate our approach with a number of applicatio...

In this paper we give efficient parallelalgorithms for a number of problems from computational geometry by using generalized versions of parallel plane sweeping. We illustrate our approach with a number of applications, which include general hidden-surface elimination (even if the overlap relation contains cycles), CSG boundary evaluation, computing the contour of a collection of rectangles, and hidden-surface elimination for rectangles. Our algorithms are for the CREW PRAM.
