Hybrid MPI: a case study on the Xeon Phi platform

Abstract New many-core architectures such as Intel Xeon Phi offer applications significantly higher power efficiency than conventional multi-core processors. However, while this processor's compute and communication performance is an excellent match for MPI applications, leveraging its potential in practice has proven difficult because of the mismatch between the MPI distributed memory model and this processor's shared memory communication hardware. Hybrid MPI is a high performance portable implementation of MPI designed for communication over shared memory hardware. It shares the heaps of all the MPI processes that run on the same node, enabling them to communicate directly without unnecessary copies. This paper describes our work to port Hybrid MPI to the Xeon Phi platform, demonstrating that Hybrid MPI offers better performance than the native Intel MPI implementation in terms of memory bandwidth, latency and benchmark performance.

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.
