Staggered Dslash Performance on Intel Xeon Phi Architecture
Proceedings of The 32nd International Symposium on Lattice Field Theory — PoS(LATTICE2014)（2014）
摘要
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).
