pub const STARPU_REDUX: starpu_data_access_mode = 8;Expand description
< Reduction mode. StarPU will allocate on the fly a per-worker buffer, so that various tasks that access the same data in ::STARPU_REDUX mode can execute in parallel. When a task accesses the data without ::STARPU_REDUX, StarPU will automatically reduce the different contributions.
Codelets contributing to these reductions with ::STARPU_REDUX must be registered with ::STARPU_RW | ::STARPU_COMMUTE access modes.
See \ref DataReduction for more details.
