Xiaoda Zhang	364858cbc9	In sharding propagation, to keep strategy consistent of parameter being used by multiple operators, we check the edge with one node of TmpIdentityInfo	2021-11-30 18:58:33 +08:00
Xiaoda Zhang	ad5ac77ae8	1) 'auto_parallel_search_mode' changes to 'search_mode'; ... 2) 'sharding_propagation' moves to 'search_mode';	2021-11-25 19:38:21 +08:00
Xiaoda Zhang	a772767265	support reshape in sharding propagation: ... 1) using 'swc index of strategy_cost_' as reshape's selected strategy; 2) when encountering reshape in BFS, select the 'swc index' with zero communication cost; 3) when encountering a reshape that is already visited, check whether there exists communication between reshape and current operator. It is OK if communication happens between two configured operators; 4) currently, two consecutive reshapes are not supported; 5) adjusting BFS structure in graph_costmodel.cc; 6) adjusting some code in step_auto_parallel.cc to avoid cyclomatic complexity.	2021-11-11 11:35:43 +08:00
