This test has been giving us trouble for a bit, seeing nondeterministic failures, skipping for now to not break out CI. Need to revisit soon though.

* zero.Init() clarification

clarify that if `model.half()` can't fit into gpu memory `zero.Init()` is a must.

this proposal is via @samyam's clarification shared elsewhere.

Thank you.

security alert related to older kramdown version

* Fix zero stage2 cpu_offload when some model trainable parameters skipped in training, as in https://github.com/microsoft/DeepSpeed/issues/707



As some model trainable parameters skipped in training,
their backward hooks in self.create_reduce_and_remove_grad_hooks() will not run, 
so they have no norm_for_param_grads

* [doc] pipeline

As @g-karthik flagged in https://github.com/microsoft/DeepSpeed/pull/659#discussion_r600132598 my previous correction PR had one sentence that said the wrong thing. So this PR attempts to rectify that. 

Thank you!

* tweak

As discussed in https://github.com/microsoft/DeepSpeed/issues/662 this PR modifies the doc:
* explains what to use instead of CUDA_VISIBLE_DEVICES
* puts the `--hostfile` cl arg in the correct place in the invocation script

What's new:

NCCL-based implementation which provides better performance and usability compared to the MPI-based implementation.
Add support to momentum masks for those parameters with constant zero gradients during training.
Bug fixes (e.g., #813).

* NCCL-based 1-bit Adam + Code Refactor for Comm. Backends (#594)

* NCCL based 1-bit Implementation + Refactor to add communication backends (#593)

* add nccl 1-bit optim.

* temporary commit to save stuff.

* Use dist collectives instead of mpi routines.

* remove old code for comm.

* Fix bugs. still does not work.

* modify to test the nccl side code path

* Initial gather impl. Works intra-node.

* Updates to comm. phase 2. nccl comm. passed the tests.

* refactor code to introduce nccl/mpi as backends for onebit adam.

* Refactor updates to test/engine.

* Fix compile/runtime errors.

* simplify support for nccl/mpi backends.

* Add missign file

*...

* Ensure gradients of other partitions are cleared after reduction

* Remove redundant code
Co-authored-by: Jeff Rasley <jerasley@microsoft.com>

* Fix mis-aligned-grad

When a parameter is not divisible by world size, the partitioned gradients are mis-aligned due to incorrect padding handling. This PR should fix for that.

* Formatting fix

* Adding static_scale test back for Z3, and also changing hidden size to be not divisile by world_size

* also removing alignment from flat fp16 buffers

* Testing for hidden dim alignment

* inference hook fix

* Update stage3.py

* formatting

* [bug-fix] move params to gpu if offload params is turned off
