Parallel computation and numerical optimisation
Annals of Operations Research, 1984In this paper we will consider the effect of introducing parallel computers to solve optimisation problems. We briefly highlight four situations where most improvements are likely. We consider the possible interaction of the four classifications with the currently available parallel processing machines.

Numerically stable parallel computation of (co-)variance
Proceedings of the 30th International Conference on Scientific and Statistical Database Management, 2018With the advent of big data, we see an increasing interest in computing correlations in huge data sets with both many instances and many variables. Essential descriptive statistics such as the variance, standard deviation, covariance, and correlation can suffer from a numerical instability known as "catastrophic cancellation" that can lead to problems ...

Prototyping Framework for Parallel Numerical Computations
2014Our research is focused on the simplification of parallel programming for distributed memory systems. Our goal is to build a unifying framework for creating, debugging, profiling, and verifying parallel applications. The result of this effort is an open source tool Kaira. In this paper, we focus on prototyping of parallel applications. We have extended

Numerical algorithms for parallel computers
Proceedings of the May 19-22, 1980, national computer conference on - AFIPS '80, 1980Numerical methods are generally judged on their ability to produce a reasonably accurate answer in a reasonable amount of time. This paper deals with the latter criterion in the context of non-standard architectures---namely vector and array processors.

Numerically intensive computing as a benchmark for parallel computer architectures
1995We compare execution time for typical numerical problems, obtained on different parallel architectures, including typical vector supercomputers, multiprocessors and network of computers with PVM environment.

Numerically-intensive "plug-and-play" parallel computing
Proceedings 2001 IEEE International Conference on Cluster Computing, 2001At UCLA's Plasma Physics Group, we have been successful in building and using a numerically-intensive parallel computing cluster using Power Macintosh hardware and the Macintosh Operating System. Our solution makes the problem of building and operating a parallel computer far easier than using other technologies, allowing the user, without expertise in

On the numerical sensitivity of computer simulations on hybrid and parallel computing systems
2011 International Conference on High Performance Computing & Simulation, 2011Simulation results depend not only on the precision of the floating point arithmetic with respect to the numerical accuracy of the results. They are also sensitive to differences of floating point arithmetic implementations of different hybrid and parallel computing systems such as CPUs, GPUs, dedicated processors like the Cell processor or the GRAPE ...
