Benefits from using mixed precision computations in the ELPA-AEO and ESSEX-II eigensolver projects

We first briefly report on the status and recent achievements of the ELPA-AEO (Eigenvalue Solvers for Petaflop Applications - Algorithmic Extensions and Optimizations) and ESSEX II (Equipping Sparse Solvers for Exascale) projects. In both collaboratory efforts, scientists from the application areas, mathematicians, and computer scientists work together to develop and make available efficient highly parallel methods for the solution of eigenvalue problems. Then we focus on a topic addressed in both projects, the use of mixed precision computations to enhance efficiency. We give a more detailed description of our approaches for benefiting from either lower or higher precision in three selected contexts and of the results thus obtained

監査役とストック・オプション

In Japan, there are not small number of cases where stock options are granted to company auditors. As for accounting auditors, they are prohibited to hold shares of the client, or receive a contingent fee. But for company auditors, they are not prohibited to receive stock options. In this paper, independence of company auditors and the member of audit committee are reviewed, and then, the effect of granting stock options to them will be discussed
