◆ barrier()

void Arcane::SequentialContigMachineShMemWinBaseInternal::barrier ( ) const

inlineoverridevirtual

Method allowing waiting until all processes/threads of the node call this method to continue execution.

Implements Arcane::MessagePassing::IContigMachineShMemWinBaseInternal.

Definition at line 427 of file SequentialParallelMng.cc.

◆ machineRanks()

ConstArrayView< Int32 > Arcane::SequentialContigMachineShMemWinBaseInternal::machineRanks ( ) const

inlineoverridevirtual

Method allowing the retrieval of the ranks that possess a segment in the window.

The order of the processes in the returned view corresponds to the order of the segments in the window.

Returns: A view containing the rank IDs.

◆ resizeSegment()

void Arcane::SequentialContigMachineShMemWinBaseInternal::resizeSegment ( const Int64 new_sizeof_segment )

inlineoverridevirtual

Method allowing the resizing of the window segments.

Collective call.

The total size of the window must be less than or equal to the original size.

Parameters

new_sizeof_segment The new size of our segment (in bytes).
