i) Got mixed precision in 2f and EOFA force and action solves.
But need mixed precision in the heatbath solve. Best for Fermop to have a "clone" method, to
reduce the number of solver and action objects. Needed ideally for the EOFA heatbath.
15% perhaps
Combine with 2x trajectory length?
ii) Rational on EOFA HB -- relax order
-- Test the approx as per David email
Resume / roll.sh
----------------------------------------------------------------
- 16^3 Currently 10 traj per hour
- EOFA use a different derivative solver from action solver
- EOFA fix Davids hack to the SchurRedBlack guessing
*** Reduce precision/tolerance in EOFA with second CG param. (10% speed up)
*** Force gradient - reduced precision solve for the gradient (4/3x speedup)
*** Need a plan for gauge field update for mixed precision in HMC (2x speed up)
-- Store the single prec action operator.
-- Clone the gauge field from the operator function argument.
-- Build the mixed precision operator dynamically from the passed operator and single prec clone.
*** Mixed precision CG into EOFA portion
*** Further reduce precision in forces to 10^-6 ?
*** Overall: a 3x or so is still possible => 500s -> 160s and 20 traj per hour on 16^3.
- Use mixed precision CG in HMC
- SchurRedBlack.h: stop use of operator function; use LinearOperator or similar instead.
- Or make an OperatorFunction for mixed precision as a wrapper
