DPCT1087#

Message#

SYCL currently does not support cross group synchronization. You can specify --use-experimental-features=nd_range_barrier to use the dpct helper function nd_range_barrier to migrate <synchronization API call>.

Detailed Help#

By default, the dpct helper function nd_range_barrier is not used to migrate CUDA* grid level synchronization. To use nd_range_barrier to migrate CUDA grid level synchronization, specify --use-experimental-features=nd_range_barrier in the migration command.

Suggestions to Fix#

Specify --use-experimental-features=nd_range_barrier in the migration command to use dpct helper function nd_range_barrier to migrate CUDA grid level synchronization.
