# Guide:
# This script supports distributed training on multi-gpu workers (as well as single-worker training). 
# Please set the options below according to the comments. 
# For multi-gpu workers training, these options should be manually set for each worker. 
# After setting the options, please run the script on each worker.
# To use the shuffled data (if exists), please uncomment the Line 24.

# Number of GPUs per GPU worker
GPUS_PER_NODE=8 
# Number of GPU workers, for single-worker training, please set to 1
WORKER_CNT=4 
# The ip address of the rank-0 worker, for single-worker training, please set to localhost
export MASTER_ADDR=XX.XX.XX.XX
# The port for communication
export MASTER_PORT=8214
# The rank of this worker, should be in {0, ..., WORKER_CNT-1}, for single-worker training, please set to 0
export RANK=0
