Hello, I was wondering if ROOT uses the stub version of cudaRT when I use it to build other libraries. I get the following error when I attempt to use a Thrust call within a .so file that was compiled in part with ROOT:
Cuda API error detected: cudaGetLastError returned (0x34)
(this is the definition from the Cuda Docs)
cudaErrorStubLibrary = 34:
This indicates that the CUDA driver that the application has loaded is a stub library. Applications that run with the stub rather than a real driver loaded will result in CUDA API returning this error.
I run on a pretty standard system with V100, all up to date drivers, Cuda 11.5 toolkit and the latest nvhpc compiler.
The exact same call works when I use it in main() instead of in a call to a simple function within the .so built with ROOT.
Would appreciate any insight!
