Description
Pcard-81867 This PR upgrades ease of launch module, it primarily addresses two issues.
- The user-provided arguments have the highest priority when launching.
- It introduces the ability to launch with IPS.
# lauch with ip list
mpirun python -m paddle.dsitributed.launch --ips=<ips1,ips2...> train.py
# lauch with hostfile
mpirun python -m paddle.dsitributed.launch --ips=<hostfile> train.py
hostfile example
10.67.224.15
10.67.224.16
10.67.224.17
...
When launching without the "master" parameter, the first IP in the IPS list will be used as the master IP, and the port will be automatically detected to form the master: ips[0]:port.
