| Outline of Final Research Achievements |
GPGPU techniques, which utilize graphic processors to accelerate general purpose computing, have become popular in the past several years. In this study, we developed a technique for efficiently executing discrete event simulations (DES) using GPGPU. Processing branches lead performance degradation in GPGPU. Thus we reduced the branches by introducing temporal redundancy. Moreover, we developed a number of software rejuvenation schemes for parallel DES. We also constructed an analytical model for evaluating reliability of a simple software rejuvenation technique.
