API: Batched¶
Overview¶
The Kokkos batched interface provides multiple functor-level interfaces for dense linear algebra (DLA) or sparse linear algebra (SLA), which correspond to Kokkos hierarchical parallelism. Unlike other batched BLAS and LAPACK interfaces, we do not provide a front-level (or subroutine) interface that launches a streaming parallel kernel. Instead, we provide a functor-level interface that can be used in Kokkos parallel expressions (e.g., parallel for, reduce and scan). The advantage of this approach is that a user can compose various batched linear algebra kernels, exploiting temporal locality via the functor-level interfaces.
