| Outline of Final Research Achievements |
In order to realize interactive simulation under massive-core supercomputing environment, we have developed two simulation frameworks that utilize the time-space similarity in the time series simulations which solve the linear equation where both the matrix A and the right hand side vector are slightly changed in each time step. The first framework is based on the speculative computation for some predicted simulation scenarios with low miss-prediction penalty. The second one is the correction based scheme which utilize SMW formula to derive the inverse matrix of A by modifying the known inverse matrix of similar matrix A' using information on the difference between A and A'. To confirm the effectiveness of these framework, we made some simulation experiments using these frameworks. As a result, we could confirm an electrical circuit simulation of 7000x7000 in size could be made real time in 100ms per time step.
