  • Abstract
    Exploiting the recently introduced very-wide vector units of the Xeon Phi coprocessor can potentially increase the scalability for scientific applications. Using lattice QCD compute kernels, the authors find that the performance achieved using the Xeon Phi coprocessors wide vector units is similar to GPGPU performance after appropriate code refactoring, requiring moderate programming effort.
