Synopsis

Documentation

Arguments

:: List	The node list; only used for node names, so any version is good (before or after the operation)
-> List	The instance list; also used for names only
-> Idx	The index of the instance being moved
-> IMove	The actual move to be described
-> [OpCode]	The list of opcodes equivalent to the given move

Convert a placement into a list of OpCodes (basically a job).

Computes the group of an instance per the primary node.

Arguments

:: [(Gdx, [Ndx])]	Group index/node index assoc list
-> IntSet	Nodes that are excluded
-> Gdx	The group for which we query the nodes
-> Result [Ndx]	List of available node indices

Computes the nodes in a given group which are available for allocation.
