Problem with devices which doesn't support cl_khr_fp64 #39

Closed dselivanov closed 8 years ago

dselivanov commented 8 years ago

Error from master 0e54a5d.

library(gpuR)
A <- seq.int(from=0, to=999)
gpuA <- gpuVector(A)

Error in deviceHasDouble(platform_index, device_index) : is_integer : gpu_idx is not of type 'integer'; it has class 'numeric'.

Seems somewhere internally we call deviceHasDouble with numeric argument. I can open new issue for that.

Works fine on develop branch - feel free to close.
