libtrilinos-kokkos-kernels-dev 12.14.1-1 (amd64 binary) in ubuntu focal

 KokkosKernels implements local computational kernels for linear algebra and
 graph operations, using the Kokkos shared-memory parallel programming model.
 "Local" means not using MPI, or running within a single MPI process without
 knowing about MPI. "Computational kernels" are coarse-grained operations;
 they take a lot of work and make sense to parallelize inside using Kokkos.
 KokkosKernels can be the building block of a parallel linear algebra library
 like Tpetra that uses MPI and threads for parallelism, or it can be used
 stand-alone in your application.
