Detailed Description

template<typename ExecSpace>
class Tpetra::Details::Spaces::InstanceLifetimeManager< ExecSpace >

Provides reusable Kokkos execution space instances.

Template Parameters

ExecSpace

the type of Kokkos execution space to manage

Holds a weak RCP to exec space instances, but provides strong RCPs to callers. Callers in Tpetra can use this to quickly get an execution space instance on-demand.

When all strong RCP holders go away, the referenced instance will also go away. This prevents the spaces from living longer than Kokkos.
