Member Function Documentation
◆ wait()
|
pure virtual |
Wait on this communication request to complete.
This is a blocking operation. The user is responsible for avoiding deadlock. This operation must also be idempotent.
Implemented in Tpetra::Details::Impl::IallreduceCommRequest< PacketType, SendLayoutType, SendDeviceType, RecvLayoutType, RecvDeviceType, 0 >, Tpetra::Details::Impl::IallreduceCommRequest< PacketType, SendLayoutType, SendDeviceType, RecvLayoutType, RecvDeviceType, 1 >, and Tpetra::Details::Impl::DeferredActionCommRequest.
◆ cancel()
|
pure virtual |
Cancel the pending communication request.
This operation must be idempotent.
Implemented in Tpetra::Details::Impl::IallreduceCommRequest< PacketType, SendLayoutType, SendDeviceType, RecvLayoutType, RecvDeviceType, 0 >, Tpetra::Details::Impl::IallreduceCommRequest< PacketType, SendLayoutType, SendDeviceType, RecvLayoutType, RecvDeviceType, 1 >, and Tpetra::Details::Impl::DeferredActionCommRequest.
