Describe the bug

rocprof shows rocprim calls being on a different stream than other kernels. This would be fine, but there can be the possibility of interacting poorly with HSA resources and such.

To Reproduce

Profile any code that uses raja HIP kernels and exclusive_scan operators.

Expected behavior

Expect to be on the same stream when profiled.

Compilers & Libraries (please complete the following information):

  • ROCM version 6.2.1
