Remove tau #215

Closed ye-luo closed 5 years ago

ye-luo commented 5 years ago

tau was used to control the acceptance ratio which can be directly changed from input. Now remove tau is equivalent to set tau=1.0

markdewing commented 5 years ago

Is there any issue with the locality of the trial moves? With small tau, are new positions sufficiently close to old positions to gain any locality (spline lookups, etc?). Would this have any effects on people investigating properties of miniqmc to apply to qmcpack?

ye-luo commented 5 years ago

The current tau is pretty large. Actually a daily run of QMCPACK never goes this large. I didn't notice any performance change on my runs.
