Polaris was a research microarchitecture designed by Intel Labs demonstarting the theoretical capabilities of a many-core chip performing 1 trillion floating point operations.
Contents
History
Polaris was originally presented at IEEE ISSCC 2007. It was a concept project designed to demonstrate the potential of integrating many processing elements on a single silicon chip enabled by Moore's Law in order to achieve a high trillion floating point operations throughput. Polaris was Intel's first public chip as a direct consequence of their Tera-scale Computing Research Program and is the basis of Intel's later research projects which paved the way for Intel's Many Integrated Cores (MIC) architecture and the Xeon Phi many-core processor family.
