# emu=1 switch to cuda emulation mode (otherwise: use gpu)
# dbg=1 print a lot of debugging output during runtime
# verbose=1 output nvcc command line during compilation
# keep=1 do not delete temporary compilation files (.ii, .cubin, ...)
# cufft=1 use cuda's fast fourier transformation lib "cufft" where possible (otherwise: use cpu fftw)
# binning=1 create virtual particle grid (neighbor-lists otherwise); currently this is not supported
# precision=1 single precision (global setting)
