* minor, but ease of life, one less papercut

- clarify that per-GPU batch size is not increased with AdaScale.

* tentatively fixing the cpu version of circleci jobs, now pipe tests are the last ones standing
* fixing oss backcompat, trying to fix rpc in old pytorch also
* fixing the file based init in torch 1.5

* min bucket size with model size
* resize the bucket after all the params have been squeezed in, save a tiny bit of memory
* minor, ensure that the cache is freed and improve the comments

* minor, not life changing but removing a dependency on runtime optim

* adding a parity unit test
* code review, better testing, use torch defaults and check for the loss, log world size

* add additional unit test
* support model parallelism in oss

* trying to fix the missing files in the pip package (not in this diff)
* adding a long description, more pypi friendly

* adding the pytest timeout plugin to properly root out hanging tests
* removing redundant code, slightly more reasonable timeout, works on single cuda
* finding the root bug for some of the cpu hangs, rpc init
* propagating all the rpc init test changes to the pipe and model parallel tests

release pip package to follow suit

* [feat] sync adascale from internal repo

- tbd

testing: tbd

* Update argument document of __init__

* update documentation around set_num_gradients_to_accumulate

* added checking code for proper API calling places

* rename internal APIs to make them internal

* updated changelog

* added support for add_param_group and its unit test

* added unit test for set_num_gradients_to_accumulate

* added debias_ewma unit test

* fixed test_set_num_gradients_to_accumulate (need zero_grad() call)

* added missing zero_grad() to test_lr_scheduler

* fixed test_add_param_group with respect to optim.zero_grad()

* added test_gradient_value

* added test_scale_not_equal_default for scale != world_size * grad_accum

* added test_unhook()

* removed print statements

* fixed a typo

* addressed Ben's comment

* fix typo, backend for CPU test

* Add function to add handle for sync BN
* Add test to ensure batch norm handles have been added

- tighter regression detection, based on the best case vs. worst case
- still run all configurations, useful for comparisons but not a target

* timeout on the process join, expose a hanging process
* make sure that teardown is always called

* removing a dead call since ShardedDDP, small speedup
* unrelated, but filling in the changelog
* another nit

* catching properly a given test failing if not enough gpus

author: Joshua Meier

* file based dist init
* nicer handling of broken world sizes vs. number of available GPUs, do not break but warn out

* Update changelog

missed this item from previous AdaScale commit.

* More change log

* Addressed review comments

* keep two torch 1.7 profiles to save cuda 10.1 testing

* fix, one liner

* adjust so that frozen trunks get spread still, even if this should have little consequences

* removing dead code, hopeful unit test fix

* now with some linting..

* adding a proper unit test case

[OSS] Getting rid of the "should bucket" hash table, just use a list + non trainable params fix (#259)

* Getting rid of the "should bucket" hash table, just use a list
Properly handle all params, with or without requires_grad

* make sure that this case is unit tested

* typo, sorry about that

* small perf fix

* Better handling of the callback queue, try to consume it as we go.

* dumping buckets for the reduce part, always the same unused params issue

* lintfixes

* come on black

* Update tutorial_pipe_multiprocess.py

make RANK global like the other tutorials

* now works on a machine without cuda
* fixes some minor typos

* [cleanup] factorize tutorials in examples

* collects duplicate code across tutorials in helpers.py

* [fix] getData in tutorials now returns iterable
