HELSON	1468e4bcfc	[zero] add constant placement policy (#1705) ... * fixes memory leak when paramter is in fp16 in ZeroDDP init. * bans chunk releasement in CUDA. Only when a chunk is about to offload, it is allowed to release. * adds a constant placement policy. With it, users can allocate a reserved caching memory space for parameters.	2022-10-14 17:53:16 +08:00
