| Abstract | With the increasing popularity of multi-core processors and the promise of future many-core systems, parallel CAD algorithm development has attracted a significant amount of research effort. However, a highly relevant issue, parallel program performance modeling has received little attention in the EDA community. Performance modeling serves the critical role of guiding parallel algorithm design and provides a basis for runtime performance optimization. We propose a systematic composable approach for the performance modeling of a recently developed hierarchical multi-algorithm parallel circuit simulation (HMAPS) approach. The unique integration of inter- and intra-algorithm parallelisms allows a multiplicity of parallelisms to be exploited in HMAPS and also creates interesting modeling challenges in forms of complex performance tradeoffs and large runtime configuration space. We model the performances of key subtask entities as functions of workload and parallelism. We address significant complications introduced by inter-algorithm interactions in terms of memory contention and collaborative simulation behavior via novel penalty and statistical based modeling. The proposed approach is able to accurately predict the parallel performance of a given HMAPS configuration and hence enables the runtime optimization of the parallel simulation code. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
