* Fix typo in copyright
* Minor README improvements
- Prevent underscores from being interpreted as italics in test name format.
- Switch URL to HTTPS.
* Update docs scripts config
- Allow run_doc.sh and run_doxygen.sh to be called from any directory.
* Add docs build to Jenkins
* Update install.sh
Install.sh having hard code like /opt/rocm/bin/hipcc for rocm_path and default_path=/opt/rocm
This will work only when we have standalone rocm installed. If anyone has installed, side-by-side, they will face below error.
Can we keep like ROCM_PATH=$ROCM_PATH instead of “default_path” as variable name and
ROCM_BIN_PATH=$ROCM_PATH/bin ,rocm_path can be replaced with ROCM_BIN_PATH.
This way, we will have option to export ROCM_PATH as env variable as per need and use the script.
I have also tried locally, it’s working. ROCM_PATH is common variable name, we are having.
If you are ok, I can also submit the PR for the same.

Optimization for Tree allreduce on A100.
Improve aggregation performance.
Use shared buffers for inter-node send/recv.
Add NVTX profiling hooks.
Accelerate alltoall connections by merging communication for all
channels.
Add support for one hop communication through NVLink, for faster
send/recv communication on cubemesh topologies like DGX-1.
Improve alltoall scheduling to better balance intra/inter node
communication.
Increase send/recv parallelism by 8x, each warp sending or
receiving to a different peer.
Net: move to v4.
Net: make flush operation asynchronous to accelerate alltoall.
Net: define maximum number of requests.
Fix hang when using LL128 protocol after 2^31 steps.
Fix#379 : topology injection failing when using less GPUs than
described in the XML.
Fix#394 : protocol mismatch causing hangs or crashes when using
one GPU per node.
