Has anyone else tried to have
device constant double variables in their code?
I’ve looked at the PTX code generated and it appears to set the values to zero.
Here’s an example line in my .cu file
__device__ __constant__ double deli=30.0;
And here’s the corresponding line in the .ptx file
.const .f64 deli = 0d0000000000000000 /* 0 */;
I’m using a GTX280 and I am compiling with architecture “-arch sm_13”
