Problems to execute benchmark on Nvidia GPU #23

Closed ruialves7 closed 3 months ago

ruialves7 commented 2 years ago

Hi,

I'm using the computecpp 2.0.0, ubuntu 20.04 and a GPU Nvidia 1070.

when i trying build your benchmark, the system return the following error: ptxas fatal : Unresolved extern function '_Z4fabsf'

What could be wrong?

Regards,

Rui

Could you provide the build commands you've used? I believe ComputeCpp's CUDA support is experimental and still lacks device libraries (i.e math functions) hence fabs is an unresolved symbol.

Closing as ComputeCpp is EOL.
