Sierra: a SIMD extension for C++

Content Provider ACM Digital Library
Author Leißa, Roland Hack, Sebastian Haffner, Immanuel
Abstract Nowadays, SIMD hardware is omnipresent in computers. Nonetheless, many software projects make hardly use of SIMD instructions: Applications are usually written in general-purpose languages like C++. However, general-purpose languages only provide poor abstractions for SIMD programming enforcing an error-prone, assembly-like programming style. An alternative are data-parallel languages. They indeed offer more convenience to target SIMD architectures but introduce their own set of problems. In particular, programmers are often unwilling to port their working C++ code to a new programming language. In this paper we present Sierra: a SIMD extension for C++. It combines the full power of C++ with an intuitive and effective way to address SIMD hardware. With Sierra, the programmer can write efficient, portable and maintainable code. It is particularly easy to enhance existing code to run efficiently on SIMD machines. In contrast to prior approaches, the programmer has explicit control over the involved vector lengths.

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.
