Staggered Dslash Performance on Intel Xeon Phi Architecture

Understand

The conjugate gradient (CG) algorithm is among the most essential and time consuming parts of lattice calculations with staggered quarks.

• We test the performance of CG and dslash, the key step in the CG algorithm, on the Intel Xeon Phi, also known as the Many Integrated Core (MIC) architecture.
• We try different parallelization strategies using MPI, OpenMP, and the vector processing units (VPUs).
