I am trying to port CHAI benchmarks <https://github.com/chai-benchmarks/chai>similarly to gem5-resources/src/gpu/pannotia <https://github.com/gem5/gem5-resources/tree/stable/src/gpu/pannotia>. I was able to HIPify (through the perl script + some manual changes) all the code files, and ran the BFS program. I see the following error message at the point of launching the CPU threads here <https://github.com/mysoreanoop/chai/blob/678c18fd551fbf12f4abbb05ab7164f1b588be68/HIP-U-gem5/BFS/main.cpp#L273> (fork of HIPified CHAI). I do not see any of the prints from the CPU threads which leads me to believe the error is to do with the threads not being launched or a related error.
(This looks related; incorporated the suggestion of linking against -pthread: https://stackoverflow.com/a/6485728) The stderr log is below; any help is appreciated. _________ ....
