HELSON	f69f9bf223	[zero] add chunk init function for users (#1729 ) * add chunk manager init function * fix unit tests * add comment * add flush=True	2 years ago
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.	2 years ago
