Opm::gpuistl::detail::CuSparseResource
The CuSparseResource class wraps a CuSparse resource in a proper RAII pattern.
Definition CuSparseResource.hpp:55
Opm::gpuistl::detail::CuSparseResource::CuSparseResource
CuSparseResource(CreatorType creator, DeleterType deleter)
CuSparseResource creates a new instance by calling creator, and will delete using deleter.

Opm::gpuistl::detail::CuSparseResource::CuSparseResource
CuSparseResource()
CuSparseResource will automatically select the proper creator and deleter based on the type (and thro...
Definition CuSparseResource_impl.hpp:91
Opm::gpuistl::detail::CuSparseResource::~CuSparseResource
~CuSparseResource()
Calls the deleter functor.
Definition CuSparseResource_impl.hpp:104
Opm::gpuistl::detail
Contains wrappers to make the CuBLAS library behave as a modern C++ library with function overlading.
