When compiling your CUDA code, you have to select for which architecture your code is being generated. nvcc
provides two parameters to specify this architecture, basically:
arch
specifies the virtual arquictecture, which can becompute_10
,compute_11
, etc.code
specifies the real architecture, which can besm_10
,sm_11
, etc.
So a command like this:
nvcc x.cu -arch=compute_13 -code=sm_13
Will generate 'cubin' code for devices with 1.3 compute capability. Please correct me if I'm wrong. Which I would like to know is which are the default values for these two parameters? Which is the default architecture that nvcc uses when no value for arch
or code
is specified?
