-Using HMC in Grid version 0.5.1
-
-These are the instructions to use the Generalised HMC on Grid version 0.5.1.
-Disclaimer: GRID is still under active development so any information here can be changed in future releases.
-
-
-Command line options
-===================
-(relevant file GenericHMCrunner.h)
-The initial configuration can be changed at the command line using 
---StartType <your choice>
-valid choices, one among these
-HotStart, ColdStart, TepidStart, CheckpointStart
-default: HotStart
-
-example
-./My_hmc_exec  --StartType HotStart
-
-The CheckpointStart option uses the prefix for the configurations and rng seed files defined in your executable and the initial configuration is specified by
---StartTrajectory <integer>
-default: 0
-
-The number of trajectories for a specific run are specified at command line by
---Trajectories <integer>
-default: 1
-
-The number of thermalization steps (i.e. steps when the Metropolis acceptance check is turned off) is specified by
---Thermalizations <integer>
-default: 10
-
-
-Any other parameter is defined in the source for the executable.
-
-HMC controls
-===========
-
-The lines 
-
-  std::vector<int> SerSeed({1, 2, 3, 4, 5});
-  std::vector<int> ParSeed({6, 7, 8, 9, 10});
-
-define the seeds for the serial and the parallel RNG.
-
-The line 
-
-  TheHMC.MDparameters.set(20, 1.0);// MDsteps, traj length
-
-declares the number of molecular dynamics steps and the total trajectory length.
-
-
-Actions
-======
-
-Action names are defined in the file
-lib/qcd/Actions.h
-
-Gauge actions list:
-
-WilsonGaugeActionR;
-WilsonGaugeActionF;
-WilsonGaugeActionD;
-PlaqPlusRectangleActionR;
-PlaqPlusRectangleActionF;
-PlaqPlusRectangleActionD;
-IwasakiGaugeActionR;
-IwasakiGaugeActionF;
-IwasakiGaugeActionD;
-SymanzikGaugeActionR;
-SymanzikGaugeActionF;
-SymanzikGaugeActionD;
-
-
-ConjugateWilsonGaugeActionR;
-ConjugateWilsonGaugeActionF;
-ConjugateWilsonGaugeActionD;
-ConjugatePlaqPlusRectangleActionR;
-ConjugatePlaqPlusRectangleActionF;
-ConjugatePlaqPlusRectangleActionD;
-ConjugateIwasakiGaugeActionR;
-ConjugateIwasakiGaugeActionF;
-ConjugateIwasakiGaugeActionD;
-ConjugateSymanzikGaugeActionR;
-ConjugateSymanzikGaugeActionF;
-ConjugateSymanzikGaugeActionD;
-
-
-ScalarActionR;
-ScalarActionF;
-ScalarActionD;
-
-
-each of these action accept one single parameter at creation time (beta).
-Example for creating a Symanzik action with beta=4.0
-
-	SymanzikGaugeActionR(4.0)
-
-The suffixes R,F,D in the action names refer to the Real
-(the precision is defined at compile time by the --enable-precision flag in the configure),
-Float and Double, that force the precision of the action to be 32, 64 bit respectively.
