#  There are a number of code options that need to be switched on/off
#  on compile-time.
#
#  From the following list, please select the desired options:

#OPT1    =  -DPERIODIC       # enables periodic boundaries conditions
OPT2     =  -DCOOLING        # radiative heating and cooling
OPT3     =  -DDIAG           # outputs performance diagnostic for tree walks
OPT4     =  -DENERGYSTATS    # outputs energy.txt file
OPT5     =  -DOUTPUTPOT      # outputs the potential energy into the snapshot
#OPT6     =  -DINFOSTATS      # outputs info.txt file
#OPT7    =  -DINLINE         # compiler accepts the `inline' statement
#OPT8    =  -DT3E            # needed on the T3E
#OPT9    =  -DRECTREECONS    # switches on recursive computation of multipole moments
OPT10     =  -DBMAX           # enables very conservative node-opening 
#OPT11   =  -DVELDISP        # selects computation of velocity dispersion/density for dark matter

OPT12    =  -DMOREPARAMS    # enables additional parameters in parameterfile for star formation 
#OPT13    =  -DSFR           # switches on star formation
#OPT14	 =  -DDIVCHECK	    # switches on criteria of convergence for star formation
#OPT15   =  -DCLOUDS        # switches on multi-phase model for star formation
#OPT16   =  -DSTELLARAGE    # Switches on computation of mean time of stellar formation redshift/age
#OPT17   =  -DSTOCHASTICSFR # switches on stochastic star formation events as opposed to continuous treatment in standard scheme

OPT18    =  -DENTROPY       # selects conservative entropy integration
#OPT19    =  -DTURBULENT     # selects turbulent model of feedback
#OPT20   =  -DALTTAU           # selects other tau's when doing feedback timescale
#OPT21    =  -DSFRHIST	   # write patrik's SFRHIST file
#OPT22    =  -DISOTHERMALGAS   # sets gas to be isothermal at temperature read in from IC file



CC       =   pgcc   # sets the C-compiler (on NERSC=mpcc, UpsAnd=pgcc  on linux=mpicc)
