Does anyone know what the default floating point compiler flags are for CUDA 6.5 compiler? Fast or IEEE 754? I’m having some floating point inconsistencies during convolutions using a model generated on MacOS.

Hi,

Default flag is IEEE 754 but fast mode is also available for nvcc.

  • 754 mode (default):
    • -ftz=false
    • -prec-div=true
    • -prec-sqrt=true
  • fast mode:
    • -ftz=true
    • -prec-div=false
    • -prec-sqrt=false

Please find more information in our document here:

Thanks.
