  • cee6a37639 Added a logging tag for HMC As the integrator logger is active by default the cmdline option to activate had no effect. Changed option to *de*activate on request ("NoIntegrator") Cleaned up generating rational approxs in the general RHMC code As the tolerance of the rational approx is not related to the CG tolerance, regenerating approxs for MD and MC if they differ only by the CG tolerance is not necessary; this has been fixed In DWF+I Gparity evolution code, added cmdline options to check the rational approximations and compute the lowest/highest eigenvalues of M^dagM for RHMC tuning In the above, changed the integrator layout to a much simpler one that completes much faster; may need additional tuning Christopher Kelly 2021-02-08 09:30:35 -05:00
