+# Megatron-DeepSpeed
+
+[Megatron-DeepSpeed](https://github.com/argonne-lcf/Megatron-DeepSpeed) is a
+scalable, highly performant library for training large language models on _any_ GPU[^any].
+
+In particular, it retains the core 4D parallelism[^4d] functionality of the
+[NVIDIA / `Megatron-LM`](https://github.com/NVIDIA/Megatron-LM)
+library, while leveraging the
+[microsoft / `DeepSpeed`](https://github.com/microsoft/DeepSpeed) library for efficient
+scaling and [🍋 saforem2 / `ezpz`](https://github.com/saforem2/ezpz)
+for automated device + backend selection.
+
+[^4d]: 4D parallelism refers to data (DP), tensor (TP), pipeline (PP), and
+    sequence (SP) parallelism degrees of freedom.
+
+[^any]: Megatron-DeepSpeed is designed to work on any GPU, including NVIDIA
+    GPUs (NCCL), AMD GPUs (RCCL), and Intel XPUs (CCL).
+
+## Getting Started
+
+1. Clone the
+   [argonne-lcf / `Megatron-DeepSpeed`](https://github.com/argonne-lcf/Megatron-DeepSpeed)
+   repository:
+
+    ```bash
+    git clone https://github.com/argonne-lcf/Megatron-DeepSpeed
+    cd Megatron-DeepSpeed
+    ```
+
+1. Setup your environment:
+
+    ```bash
+    export PBS_O_WORKDIR=$(pwd)
+    source <(curl -s https://raw.githubusercontent.com/saforem2/ezpz/refs/heads/main/src/ezpz/bin/utils.sh)
+    ezpz_setup_env
+    ```
+
+1. Install dependencies:
+
+    1. 🍋 [saforem2 / `ezpz`](https://github.com/saforem2/ezpz):
+
+        ```bash
+        python3 -m pip install -e "git+https://github.com/saforem2/ezpz#egg=ezpz" --require-virtualenv
+        ```
+
+    1. [microsoft / `DeepSpeed`](https://github.com/microsoft/DeepSpeed):
+
+        ```bash
+        python3 -m pip install deepspeed
+        ```
+
+1. Launch training:
+
+    ```bash
+    # Before launching, `PBS_O_WORKDIR` should be set to Megatron-DeepSpeed's PATH
+    # and venv inside Megatron-DeepSpeed/venv should be activated.
+    TP=2 NLAYERS=10 DATA_FILE_LIST=ALCF/data-lists/aurora/books.txt bash train_aGPT_7B.sh
+    ```
+
+    This will launch a distributed pre-training run with:
+
+    - `NLAYERS=10`: Llama style model consisting of 10 layers
+
+      - `TP=2`: Split across 2 Tensor Parallel groups
+
+    - `DATA_FILE_LIST`: Using the
+    [Books corpus](https://github.com/argonne-lcf/Megatron-DeepSpeed/blob/main/ALCF/data-lists/aurora/books.txt)
+    of the Dolma dataset
+
+    ??? note "Overridable Options"
+
+        This is a simple subset of the overridable options.
+
+        The full list (as well as their default values) can be found in
+        [ALCF / `helpers.sh`](https://github.com/argonne-lcf/Megatron-DeepSpeed/blob/main/ALCF/helpers.sh)
