Detailed Description

Gang metadata registry.

void stapl::runtime::gang_md_registry::initialize	(	const process_id	pid,
		const unsigned int	npids
	)

static

Initializes the registry.

Parameters

pid	Current process id.
npids	Number of processes.

void stapl::runtime::gang_md_registry::finalize ( void )

static

Finalizes the registry.

Waits for all gang_md objects to be unregistered.

boost::intrusive_ptr< fence_md > stapl::runtime::gang_md_registry::get_fence_md ( const gang_id gid )

static

Returns a pointer to the temporary fence metadata associated with the gang with id gid.

If the metadata does not exist, it will create it.

void stapl::runtime::gang_md_registry::erase_fence_md ( fence_md *const p )

static

Erases the temporary fence metadata.

It will update the metadata of the gang_md object associated with p.
