Supercomputing operating systems: a naive view from over the fence

Content Provider ACM Digital Library
Author Roscoe, Timothy
Abstract To exaggerate unfairly, from the perspective of mainstream OS research, the supercomputing community has a very different idea of the role (and appropriate design) of an OS. HPC people regard the OS as an annoying source of noise, whereas the former crowd see it as a thing of wondrous beauty and elegance, a sine qua non of usable everyday computing. This situation has existed without serious conflict erupting for years: OS researchers worried about PCs with one core (or, at most, a handful of cores) running a general-purpose OS and supporting a dynamic, bursty, diverse mix of hundreds of interactive, long-running, soft-realtime and/or background processes. Supercomputing people wanted one, highly parallel, program to finish as soon as possible so they could get on to the next one. With multicore, this all changed: highly parallel tasks will be the norm for future general-purpose computing. In 2007, my colleagues and I eagerly embarked on a new research OS for multicore computing, and looked forward to applying long-ignored (in our field) results from the HPC realm to our system. It didn't quite work out that way. In this talk I will look at what we found to be common to the two fields, and what we didn't, and speculate on where this might be going. I think there is a useful conversation to be had, and I'd like to help revive it.

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.
