specfem::execution::VoidPolicy

template<typename ExecutionSpace>
class VoidPolicy

VoidPolicy class is used when there is no valid index to iterate over.

This policy is used as a placeholder when no iteration is needed.

using execution_space = ExecutionSpace

Execution space type for the void policy.

Public Static Attributes

static constexpr PolicyType policy_type = PolicyType::VoidPolicy

Indicates this is a void policy.

static constexpr bool is_top_level_policy = false

Indicates this is not a top-level policy.

specfem::execution::RangePolicy

template<typename ParallelConfig>
class RangePolicy : public Kokkos::RangePolicy<ParallelConfig::execution_space>

Public Types

using base_policy_type = Kokkos::RangePolicy<typename ParallelConfig::execution_space>

Base policy type. Evaluates to Kokkos::RangePolicy

using policy_index_type = typename base_policy_type::index_type

specfem::execution::TeamPolicy

template<typename ParallelConfig>
class TeamPolicy : public Kokkos::TeamPolicy<ParallelConfig::execution_space>

Base class for all iterators using on Kokkos::TeamPolicy.

Template Parameters:

ParallelConfig – Configuration for parallel execution. specfem::parallel_configurationuration::team_config

using policy_index_type = typename base_policy_type::member_type

Policy index type.

using execution_space = typename base_policy_type::execution_space

Execution space type.

Public Static Attributes

static constexpr PolicyType policy_type = PolicyType::KokkosPolicy

specfem::execution::TeamThreadRangePolicy

template<typename TeamMemberType, typename IndexType>
class TeamThreadRangePolicy : public decltypeKokkos::TeamThreadRangestd::declval<TeamMemberType>, private std::declval<IndexType>

TeamThreadRangePolicy class is used to iterate over a range of indices within a Kokkos team.

This policy is used to iterate over a range of indices in a team parallel execution context.

Template Parameters:

• TeamMemberType – The type of the Kokkos team member.

• IndexType – The type of the index to iterate over.

Subclassed by specfem::execution::ChunkEdgeIterator< DimensionTag, ViewType, KokkosIndexType >, specfem::execution::ChunkFaceIterator< DimensionTag, ViewType, KokkosIndexType >, specfem::execution::ChunkedInterfaceIntersectionIterator< DimensionTag, ViewType, KokkosIndexType >

Public Types

using policy_index_type = IndexType

Policy index type. Must be convertible to integral type.

using execution_space = typename TeamMemberType::execution_space

Execution space type.

Public Functions

inline TeamThreadRangePolicy(const TeamMemberType &team, const IndexType &range)

Constructs a TeamThreadRangePolicy for a given team member and range.

Parameters:

• team – The Kokkos team member.
