In this paper, we consider the solution of a medium-size symmetric eigenvalue problem on a massively parallel computer using the block Jacobi method. We compare parallel cyclic block Jacobi methods using 1-dimensional and 2-dimensional data distribution and show that the latter has advantages in terms of the number of processors that can be used and the… (More)
This work validates a method for increasing the radial restoring force on the voice coil in audio speakers containing ferrofluid. In addition, a study is made of factors influencing splash loss of the ferrofluid due to shock. Ferrohydrodynamic analysis is employed throughout to model behavior, and predictions are compared to experimental data.
