(The above required exposing the gauge implementation to the HMC class through the Integrator class)
Made the random shift optional (default on) through a parameter in HMCparameters
Modified ConjugateBC::CshiftLink such that it supports any shift in -L < shift < L rather than just +-1
Added a tester for the BC-respecting Cshift
Fixed a missing system header include in SSE4 intrinsics wrapper
Fixed sumD_cpu for single-prec types performing an incorrect conversion to a single-prec data type at the end, that fails to compile on some systems
Added a bounds-check function for the RHMC with arbitrary power
Added a pseudofermion action for the rational ratio with an arbitrary power and a mixed-precision variant of the same. The existing one-flavor rational ratio class now uses the general class under the hood
To support testing of the two-flavor even-odd ratio pseudofermion, separated the functionality of generating the random field and performing the heatbath step, and added a method to obtain the pseudofermion field
Added a new HMC runner start type: CheckpointStartReseed, which reseeds the RNG from scratch, allowing for the creation of new evolution streams from an existing checkpoint. Added log output of seeds used when the RNG is seeded.
EOFA changes:
To support mixed-precision inversion, generalized the class to maintain a separate solver for the L and R operators in the heatbath (separate solvers are already implemented for the other stages)
To support mixed-precision, the action of setting the operator shift coefficients is now maintained in a virtual function. A derived class for mixed-precision solvers ensures the coefficients are applied to both the double and single-prec operators
The ||^2 of the random source is now stored by the heatbath and compared to the initial action when it is computed. These should be equal but may differ if the rational bounds are not chosen correctly, hence serving as a useful and free test
Fixed calculation of M_eofa (previously incomplete and #if'd out)
Added functionality to compute M_eofa^-1 to complement the calculation of M_eofa (both are equally expensive!)
To support testing, separated the functionality of generating the random field and performing the heatbath step, and added a method to obtain the pseudofermion field
Added a test program which computes the G-parity force using the 1 and 2 flavor implementations and compares the result. Test supports DWF, EOFA and DSDR actions, chosen by a command line option.
The Mobius EOFA force test now also checks the rational approximation used for the heatbath
Added a test program for the mixed precision EOFA compared to the double-prec implementation,
G-parity HMC test now applied GPBC in the y direction and not the t direction (GPBC in t are no longer supported) and checkpoints after every configuration
Added a test program which computes the two-flavor G-parity action (via RHMC) with both the 1 and 2 flavor implementations and checks they agree
Added a test program to check the implementation of M_eofa^{-1}
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
