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.
