Christopher Kelly 80176b1b39 RHMC now outputs some initial norms to the logs
Fixed DWF+I Gparity binaries not correctly assigning twist directions (thanks Peter!)

Christopher Kelly 29ddafd0fc Added variant of G-parity DWF+I ensemble gen code using double prec RHMC 2021-04-30 13:12:24 -04:00
Christopher Kelly e0e42873c1 Const correctness for Lattice::Replicate
Adapted GeneralEvenOddRationalRatio and Test_rhmc_EOWilsonRatio_doubleVsMixedPrec to recent changes that require passing in serial RNG

For GeneralEvenOddRationalRatio and TwoFlavourEvenOddRatio, broke refresh into two stages, the first of which generates the random field and the second that computes the pseudofermion field.
This allows derived classes to override the generation of the random field, for example in testing.

Test_dwf_gpforce now uses Gparity in x-direction and APBC in time as opposed to G-parity in time

Added Test_action_dwf_gparity2fvs1f that compares the DWF fermion action with the 2f and the 1f (doubled-lattice) implementations of Gparity

Christopher Kelly d5ab571a89 Added the ability to apply a custom "filter" to the conjugate momentum in the Integrator classes, applied both after refresh and after applying the forces
Added a conjugate momentum "filter" that applies a phase to each site. With sites set to 1.0 or 0.0 this acts as a mask and enables, for example, the freezing of inactive gauge links in DDHMC
Added tests/forces/Test_momentum_filter demonstrating the use of the filter to freeze boundary links

Christopher Kelly e0f6a146d8 To DWF+I G-parity evolution code, added ability to specify number of MD steps in params and an optional usage mode that reads the config and checks the plaq/checksum agree then exits 2021-02-16 10:41:52 -05:00
Christopher Kelly daa095c519 Fixed an obscure but reproducible hang in the RHMC caused by the bounds check being activated by a random number that wasn't synchronized over the nodes
HMC now also reports the "L-infinity norm" of the impulse, aka the largest site norm

Christopher Kelly 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
2021-02-08 09:30:35 -05:00
Christopher Kelly 6cc3ad110c Improved logging output for RHMC bounds checks

Christopher Kelly 1b84f59273 Added a mixed precision multishift algorithm for which the matrix multiplies are performed in single precision but the search directions are accumulated in double precision.
A reliable update step is performed at a tunable frequency to correct the residual. A final mixed-prec single-shift solve is performed on each pole to perform cleanup if necessary.
A test is provided to demonstrate the algorithm.
