Hardware support for protective and collaborative cache sharing

Content Provider ACM Digital Library
Author Brock, Jacob Parihar, Raj Ding, Chen Huang, Michael C.
Abstract Shared caches are generally optimized to maximize the overall throughput, fairness, or both, among multiple competing programs. In shared environments and compute clouds, users are often unrelated to each other. In such circumstances, an overall gain in throughput does not justify an individual loss. This paper explores cache management policies that allow conservative sharing to protect the cache occupancy for individual programs, yet enable full cache utilization whenever there is an opportunity to do so. We propose a hardware-based mechanism called cache rationing. Each program is assigned a portion of the shared cache as its ration. The hardware support protects the ration so it cannot be taken away by peer programs while in use. However, a program can exceed its pre-allocated ration, but only if another program has unused space in its allocated portion of ration. We show that rationing provides good resource protection and full cache utilization of the shared cache for a variety of co-runs. .

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.
