-TODO: 
-********************************************************************
-
-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
