Numerical experiments using deflation with the HISQ action


  • Dr. Craig MCNEILE

Primary authors


The use of deflation is a common technique to speed up the calculation of quark propagators for Wilson/clover or domain wall fermions. I report on numerical experiments using deflation to compute quark propagators for the HISQ improved staggered action. The method is tested on HISQ gauge configurations, generated by the MILC collaboration, with lattice spacings of 0.15 fm, with a range of volumes, and quark masses down to the physical quark mass. I present preliminary results on using these methods for disconnected diagrams.
