Detailed Description

This class wraps a Ginkgo Executor for use in MFEM. Note that objects in the Ginkgo namespace intended to work together, e.g. a Ginkgo solver and preconditioner, should use the same GinkgoExecutor object. In general, most users will want to create one GinkgoExecutor object for use with all Ginkgo-related objects. The wrapper can be created to match MFEM's device configuration.

Constructor & Destructor Documentation

mfem::Ginkgo::GinkgoExecutor::GinkgoExecutor ( ExecType  exec_type)

Constructor. Takes an GinkgoExecType argument and creates an Executor.

Definition at line 31 of file ginkgo.cpp.

mfem::Ginkgo::GinkgoExecutor::GinkgoExecutor ( Device mfem_device)

Constructor. Takes an MFEM Device object and creates an Executor that "matches" (e.g., if MFEM is using the CPU, Ginkgo will choose the OmpExecutor; if MFEM is using CUDA, Ginkgo will choose the CudaExecutor).
