Namespaces
namespace	peano4
namespace	peano4.api
namespace	peano4.api.taskgraph
	The task graph abstraction allows users to formalise their solver steps over small task graphs which are then lowered into a sequence of Peano mesh traversals.
namespace	peano4.api.taskgraph.compiler
	Compilers are simple functions.
namespace	peano4.api.taskgraph.compiler.DeriveLoadStoreComputeFlag

Functions
None	peano4.api.taskgraph.compiler.DeriveLoadStoreComputeFlag.derive_load_store_compute_flag (List["peano4.api.solversteps.Step"] steps)
	For every submodel used anywhere in steps, derive a peano4::grid::constructLoadStoreComputeFlag(...) expression from which of its using Steps are active, and assign it to that submodel's generator.load_store_compute_flag - the runtime counterpart to peano4.api.taskgraph.compiler.PropagateUseStatements.propagate_use_statements(), which has to run before whichever compiler produces these steps: it decides which tasks have to declare a submodel at all; this function decides, for every Step that does, what its generated Observer should actually do with the data once the submodel's stack storage puts it there (load a real value, or start from a fresh dummy; store the result back, or discard it) - by asking, at runtime, which Step is presently executing.

	peano4.api.taskgraph.compiler.DeriveLoadStoreComputeFlag._load_store_compute_flag_holder (submodel)
	The object holding the submodel's load_store_compute_flag: The peano4_mpi_and_storage_aspect for DaStGen2 data, the generator otherwise.
