Implementation and Evaluation of a Parallel-External Algorithm for Cycle Structure Computation on a PC-Cluster
Abstract: We report on our experiences with the implementation of a parallel algorithm to compute the cycle structure of a permutation given as an oracle. As a sub-problem, the cyc...

Refined Method for the Fast and Exact Computation of Moment Invariants
Geometric moments have been proven to be a very efficient tool for description and recognition of binary shapes. Numerous methods for effective calculation of image moments have be...

Distant I/O: One-Sided Access to Secondary Storage on Remote Processors
We propose a new parallel, noncollective I/O strategy called Distant I/O that targets clustered computer systems in which disks are attached to compute nodes. Distant I/O allows o...

Exposing I/O Concurrency with Informed Prefetching
Informed prefetching provides a simple mechanism for I/O-intensive, cache-ineffective applications to efficiently exploit highly-parallel I/O subsystems such as disk arrays. This ...

On B-Tree Indices for Skewed Distributions
It is often the case that the set of values over which a B-Tree is constructed has a skewed distribution. We present a geometric growth technique to manage postings records in suc...
