CUDA 5: Enabling Dynamic Parallelism
I finally got a GPU capable of dynamic parallelism, so I finally decided to mess around with CUDA 5. But I discovered a couple of configuration options that are required if you want to enable dynamic parallelism. You’ll know you haven’t configured things correctly if you attempt to call a kernel from the device and you get the following error message:
ptxas : fatal error : Unresolved extern function ‘cudaGetParameterBuffer’
Note: this assume you have already selected the appropriate CUDA 5 build customizations for your project
Open the project project properties
- Make sure to set “Generate Relocatable Device Code” to “Yes (-rdc=true)”
- Set “code generation” to “compute_35,sm_3″
- Finally add “cudadevrt.lib” to the CUDA Linker’s “Additional Dependencies”
