Detailed Description

Physical region objects are used to manage access to the physical instances that hold data. They are lightweight handles that can be stored in data structures and passed by value. They should never escape the context in which they are created.

Member Function Documentation

get_fields()

void Legion::PhysicalRegion::get_fields

(

std::vector< FieldID > &

fields

)

const

Return a list of fields that the physical region contains.

get_logical_region()

LogicalRegion Legion::PhysicalRegion::get_logical_region

(

void

)

const

Returns

the logical region for this physical region

get_memories()

void Legion::PhysicalRegion::get_memories	(	std::set< Memory > &	memories,
		bool	silence_warnings = false,
		const char *	warning_string = NULL
	)		const

Return the memories where the underlying physical instances locate.

get_privilege()

PrivilegeMode Legion::PhysicalRegion::get_privilege

(

void

)

const

Returns

the privilege mode for this physical region

is_mapped()

bool Legion::PhysicalRegion::is_mapped

(

void

)

const

Check to see if this represents a mapped physical region.

is_valid()

bool Legion::PhysicalRegion::is_valid

(

void

)

const

For physical regions returned from inline mappings, this call will query if the instance contains valid data yet.

Returns

whether the region has valid data

wait_until_valid()

void Legion::PhysicalRegion::wait_until_valid	(	bool	silence_warnings = false,
		const char *	warning_string = NULL
	)

For physical regions returned as the result of an inline mapping, this call will block until the physical instance has a valid copy of the data. You can silence warnings about this blocking call with the 'silence_warnings' parameter.
