  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).
