Our vectorized Helmholtz solver runs at 85% efficiency on a NEC SX-5. The most time-consuming parts have been ported on SMP, NUMA, and cluster architectures. It is shown that an OpenMP version can deliver similar performance when running it on a 16 process ...
Dynamic Parallel Schedules (DPS) is a high-level framework for developing parallel applications on distributed memory computers such as clusters of PCs. DPS applications are defined by using directed acyclic flow graphs composed of user-defined operations. ...
In this paper, we examine the causes and effects of contentionfor shared data access in parallel programs running on a software distributed shared memory (DSM) system. Specifically, we experiment on two widely-used, pagebased protocols, Princeton’s home-ba ...
Distributed shared-memory (DSM) multi- processors provide a scalable hardware platform, but lack the necessary redundancy for mainframe-level reliability and availability. Chip-level redundancy in a DSM server faces a key challenge: the increased latency t ...
The vast majority of papers on distributed computing assume that processes are assigned unique identifiers before computation begins. But is this assumption necessary? What if processes do not have unique identifiers or do not wish to divulge them for re ...

Dynamic Parallel Schedules (DPS) is a high-level framework for developing parallel applications on distributed memory computers (e.g. clusters of PC). Its model relies on compositional customizable split-compute-merge graphs of operations (directed acyclic ...
In shared memory programs contention often occurs at the transition between a sequential and a parallel section of the code. As all threads start executing the parallel section, they often access data just modified by the thread that executed the sequentia ...
SFIO, Parallel File Striping for MPI-I/O Emin Gabrielyan EPFL, Computer Science Dept. Peripheral Systems Lab. Emin.Gabrielyan@epfl.ch Abstract This paper presents the design and evaluation of a Striped File I/O (SFIO) library for parallel I/O in an MPI env ...
In this paper, methods and algorithms are presented for an efficient slicing process specifically designed for microstereolithography, a high-resolution rapid prototyping technology. Modifications are given for different implementation environments (FPU, P ...
