etmc / tmLQCD

tmLQCD is a freely available software suite providing a set of tools to be used in lattice QCD simulations. This is mainly a HMC implementation (including PHMC and RHMC) for Wilson, Wilson Clover and Wilson twisted mass fermions and inverter for different versions of the Dirac operator. The code is fully parallelised and ships with optimisations for various modern architectures, such as commodity PC clusters and the Blue Gene family.

bug fix: wrong plaquette in metadata just after reversibility check #469

Closed palao closed 4 years ago

palao commented 5 years ago

The xlf-info LIME record contained a wrong value of the plaquette when the reversibility check occurs. To reproduce it, take for instance "sample-input/sample-hmc0.input" and set (to make it simpler and faster) for instance: Measurements = 11 ReversibilityCheckIntervall = 10

The plaquette value in the "xlf-info" header of the resulting conf is wrong (it corresponds to the plaquette computed on the reversed trajectory). I checked that the averaged plaquette computed and the value written in "output.data" agree and both disagree with the value in the "xlf-info".

Agreed, this was not correct!
