DPCT1087¶
Message¶
DPC++ 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 <grid type variable name>.sync()
.
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.
