Array API standard conformance tests failed to run. |
onetrace tool on linux uses execvp to start the application to trace. It sets LD_PRELOAD and PTI_ENABLE environment variables https://github.com/intel/pti-gpu/blob/master/loader/loader.cc#L216-L217 The check is added, on Linux, to confirm once that environment does contain expected variables, and emit a warning otherwise.

Deleted rendered PR docs from intelpython.github.com/dpctl, latest should be updated shortly. 🤞 |
