Parallel computation and numerical optimisation

Annals of Operations Research, 1984
In 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, 2018
With 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 ...

Parallel shadow execution to accelerate the debugging of numerical errors

ESEC/SIGSOFT FSE, 2021
This paper proposes a new approach for debugging errors in floating point computation by performing shadow execution with higher precision in parallel. The programmer specifies parts of the program that need to be debugged for errors.

Task Offloading and Scheduling in Fog RAN: A Parallel Communication and Computation Perspective

IEEE Wireless Communications Letters, 2020
Due to the parallel computing at tiered computing nodes, fog radio access network (RAN) can facilitate computation offloading. Apart from the parallel computing, communication and computation operations can be conducted simultaneously at tiered computing

Parallel numerical computations of projectile flow fields

17th Applied Aerodynamics Conference, 1999
Abstract : A time-marching, Navier-Stokes code, successfully used over a decade for projectile aerodynamics, was chosen as a test case and optimized to run on modern reduced instruction set computer (RISC)-based parallel computers. The parallelized version of the code has been used to compute the axisymmetric and three-dimensional (3-D) turbulent flow ...
