cuda::experimental::stf::frozen_logical_data

template<typename T>
class frozen_logical_data

Frozen logical data are logical data which can be accessed outside tasks.

They are created using ctx.freeze, which returns a frozen_logical_data object. The get() and unfreeze() method allow to get an instance of the frozen data that is valid until unfreeze is called.
