Task graph based system partitioning for multirate integration

Content Provider ACM Digital Library
Author Flehmig, Martin Waurich, Volker
Abstract Models with loosely coupled subsystems and network models are often characterised by subsystems of different dynamics. Therefore, mulirate methods have been brought into the EOOLT community over the last couple of years. These methods split the system into a fast and a slow part and integrate them using different step sizes to obtain faster simulations. Besides the numerical properties of multirate methods, an important challenge is to divide the system into a manageable number of subpartitions which can be assigned to a suitable step size. This paper presents a promising approach towards system partitioning for multirate integration that is based on a systems task graph. The proposed algorithms and the guard mechanism aim to reduce the overhead of the multirate method which is introduced by deciding between active and latent variables at simulation execution time.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
