# 16B parameter model.
# This config will work out of the box for any number of v5e-256 slices.
#
# Command Flags:
# OUTPUT_PATH (Required, unless base_output_directory is already set in base.yml)
# DATASET_PATH (Required, unless dataset_path is already set in base.yml)
# RUN_NAME (Required, unless run_name is already set in base.yml or running with XPK/GKE)
# PLATFORM (Optional, can be "gke" or "gce", default is "gce")
#
# Example to invoke this script:
# bash MaxText/configs/v5e/16b.sh RUN_NAME="<your_run_name>" OUTPUT_PATH="gs://<your_output_path>" DATASET_PATH="gs://<your_dataset_path>" PLATFORM="gke"
#
# Example to AOT compile:
# bash MaxText/configs/v5e/16b.sh EXECUTABLE=train_compile.py M_COMPILE_TOPOLOGY=v5e-256 M_COMPILE_TOPOLOGY_NUM_SLICES=2


# Stop execution if any command exits with error
set -e

export PLATFORM="gce"
export EXECUTABLE="train.py" # or train_compile.py

# Set environment variables
for ARGUMENT in "$@"; do
    IFS='=' read -r KEY VALUE <<< "$ARGUMENT"
    export "$KEY"="$VALUE"
done

# The setup accommodates two cases:
# 1) Passing the 'RUN_NAME' variable at runtime
# 2) Propagating the 'M_RUN_NAME' variable within an Airflow sweeping workflow
if [ -n "$RUN_NAME" ];
then
    export M_RUN_NAME=$RUN_NAME

# Set up network optimizations
bash preflight.sh PLATFORM=$PLATFORM

# Train
