The call to
uniform()is getting executed inhandle.get_stream()and kernels/operations afteruniform()are executed in separately createdstream. This causes synchronization hazard. When default RNG was changed from Philox to PCG, the bug got exposed due to the relative difference in generation speed of PCG and Philox (PCG is faster). Adding a stream synchronization call fixes the issue.
