Characteristics of adaptive runtime systems in HPC

Content Provider ACM Digital Library
Author Kale, Laxmikant V.
Abstract The phrase "Runtime System" is somewhat broad and is used with differing meanings in differing contexts. The Java runtime and most of the MPI runtimes are focused on providing mechanisms. In contrast, adaptive runtime systems emphasize strategies, in addition to providing mechanisms. This talk will look at some characteristics that make HPC RTSs adaptive. These include dynamic load balancing, exploitation of the "principle of persistence" to learn from recent data, automatic allocation to heterogeneous processors, automatic optimization of communication, application reconfiguration via control-points, automated control and optimization of temperature/power/energy/execution-time, automated tolerance of component failures so as to maintain the rate of computational progress in presence of such failures, and adapting to memory availability. The talk will examine these characteristics, and what features are necessary and/or desirable to empower the runtime system. I will illustrate it using examples from the runtime system underlying Charm++ and Adaptive MPI.

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.
