* change NCCL_ALL to NCCL_INIT
* remove extra pointer functions in transport/net.cc
[ROCm/rccl commit: d52b6c0d24]
The default value of unroll factor is 2. Changing the unroll
factor to 4 provides better performance for most of the collectives.
[ROCm/rccl commit: 4d1cfb17c8]
Added a RCCL_MSCCL_ENABLE_DONE_EVENT env var, set it be 0 by default.
The env var is to control whether to use doneEvent when invoking MSCCL
kernels.
Skipping doneEvent would cause the firmware to skip L2 cache flush,
resulting in overall performance improvement.

* Revert "Ensure memory copy integrity during transport setup (#731)"
This reverts commit 0c0c35927a.
Add stream synchronization in ncclStrongStreamRelease.
* Use event record and wait
