Detailed Description
This class provides a light-weight synchronization primitive for external applications to use when performing synchronization with Legion tasks. It allows for control to be passed from the external application into Legion and then for control to be handed back to the external application from Legion. The user can configure which direction occurs first when constructing the handshake object.
Member Function Documentation
◆ advance_legion_handshake()
| void Legion::LegionHandshake::advance_legion_handshake | ( | void | ) | const |
Advance the handshake associated with the Legion side
◆ ext_handoff_to_legion()
| void Legion::LegionHandshake::ext_handoff_to_legion | ( | void | ) | const |
◆ ext_wait_on_legion()
| void Legion::LegionHandshake::ext_wait_on_legion | ( | void | ) | const |
A blocking call that will cause this participant to wait for all Legion participants to hand over control to the external application.
◆ get_legion_arrive_phase_barrier()
| PhaseBarrier Legion::LegionHandshake::get_legion_arrive_phase_barrier | ( | void | ) | const |
Get the Legion phase barrier associated with arriving on the handshake
◆ get_legion_wait_phase_barrier()
| PhaseBarrier Legion::LegionHandshake::get_legion_wait_phase_barrier | ( | void | ) | const |
Get the Legion phase barrier associated with waiting on the handshake
◆ legion_handoff_to_ext()
| void Legion::LegionHandshake::legion_handoff_to_ext | ( | void | ) | const |
A non-blocking call to signal to the external application that this participant is ready to pass control to to it.
◆ legion_wait_on_ext()
| void Legion::LegionHandshake::legion_wait_on_ext | ( | void | ) | const |
A blocking call that will cause this participant to wait for all external participants to hand over control to Legion.
