spcl/dace: DaCe 0.12

API Changes Important: Pattern-matching transformation API has been significantly simplified. Transformations using the old API must be ported! Summary of changes: Transformations now expand either the SingleStateTransformation or MultiStateTransformation classes instead of using decorators Patterns must be registered as class variables called PatternNodes Nodes in matched patterns can be then accessed in can_be_applied and apply directly using self.nodename The name strict is now replaced with permissive (False by default). Permissive mode allows transformations to match in more cases, but may be dangerous to apply (e.g., create race conditions). can_be_applied is now a method of the transformation The apply method accepts a graph and the SDFG. Example of using the new API: import dace from dace import nodes from dace.sdfg import utils as sdutil from dace.transformation import transformation as xf class ExampleTransformation(xf.SingleStateTransformation): # Define pattern nodes map_entry = xf.PatternNode(nodes.MapEntry) access = xf.PatternNode(nodes.AccessNode) # Define matching subgraphs @classmethod def expressions(cls): # MapEntry -> Access return [sdutil.node_path_graph(cls.map_entry, cls.access)] def can_be_applied(self, graph: dace.SDFGState, expr_index: int, sdfg: dace.SDFG, permissive: bool = False) -> bool: # Returns True if the transformation can be applied on a subgraph if permissive: # In permissive mode, we will always apply this transformation return True return self.map_entry.schedule == dace.ScheduleType.CPU_Multicore def apply(self, graph: dace.SDFGState, sdfg: dace.SDFG): # Apply the transformation using the SDFG API pass Simplifying SDFGs is renamed from sdfg.apply_strict_transformations() to sdfg.simplify() AccessNodes no longer have an AccessType field. Other changes More nested SDFG inlining opportunities by default with the multi-state inline transformation Performance optimizations of the DaCe framework (parsing, transformations, code generation) for large graphs Support for Xilinx Vitis 2021.2 Minor fixes to transformations and deserialization Full Changelog: https://github.com/spcl/dace/compare/v0.11.4...v0.1
