Intel Developer Cloud Quick Start Guide¶
This document provides instructions on setting up the Intel® Gaudi® 2 AI accelerator instance on the Intel Developer Cloud and running models from the Intel Gaudi Model References repository and the Hugging Face Optimum Habana library.
Please follow along with the video on our Developer Page to walk through the steps below. To set up a multi-node instance with two or more Gaudi nodes, refer to Setting up Multiple Gaudi Nodes.
Creating an Account and Getting an Instance¶
Follow the below steps to get access to the Intel Developer Cloud and launch a Gaudi 2 card instance.
Go to https://console.cloud.intel.com and select Getting Started to create an account and get SSH access.
Go to Console Home and select Hardware catalog:
Select the Gaudi 2 Deep Learning Server:
In the instance Configuration window, enter an instance name and select the SSH key that you created in the Getting Started section. Click “Launch”. You will see that the node is being provisioned:
Once the State has changed from “provisioning” to “ready”, click on the instance name. Then select the “How to Connect” box:
You will then see all the options to SSH into the Developer Cloud instance. Copy the SSH command and paste it into your terminal window:
Note
If you do not have access to the Gaudi 2 instance, you will need to request access to be added to the wait list.
Start Training a PyTorch Model on Gaudi 2¶
Note
For partners not using the Intel Developer Cloud, follow the instructions starting from this section to run models using Gaudi.
Now that the instance has been created, start with some simple model examples from the Intel Gaudi Model References GitHub repository.
Run the
hl-smitool to confirm the Intel Gaudi software version used on your Developer Cloud instance. You will need to use the correct software version in thedocker runcommand in step 1 below, and in thegit clonecommand in step 2: use the HL-SMI Version at the top. In this case, the version is 1.15.1:HL-SMI Version: hl-1.15.1-XXXXXXX Driver Version: 1.15.1-XXXXXXRun the Intel Gaudi Docker image:
docker run -it --runtime=habana -e HABANA_VISIBLE_DEVICES=all -e OMPI_MCA_btl_vader_single_copy_mechanism=none --cap-add=sys_nice --net=host --ipc=host vault.habana.ai/gaudi-docker/1.15.1/ubuntu22.04/habanalabs/pytorch-installer-2.2.0:latest
Clone the Model References repository inside the container that you have just started:
cd ~ git clone -b 1.15.1 https://github.com/HabanaAI/Model-References.git
Move to the subdirectory containing the hello_world example:
cd Model-References/PyTorch/examples/computer_vision/hello_world/
Update the environment variables to point to where the Model-References repository is located and set PYTHON to python executable:
export PYTHONPATH=$PYTHONPATH:/root/Model-References export PYTHON=/usr/bin/python3.10
Training on a Single Gaudi Card¶
Run training on a single HPU in BF16 with autocast enabled. This is a simple linear regression model. Copy this run command into your terminal window:
$PYTHON mnist.py --batch-size=64 --epochs=1 --lr=1.0 --gamma=0.7 --hpu --autocast
The following shows the expected output:

Fine-tuning with Hugging Face Optimum Habana Library¶
The Optimum Habana library is the interface between the Hugging Face Transformers and Diffusers libraries and the Gaudi 2 card. It provides a set of tools enabling easy model loading, training and inference on single and multi-card settings for different downstream tasks. The following example uses the text-classification task to fine-tune a BERT-Large model with the MRPC (Microsoft Research Paraphrase Corpus) dataset and also run inference.
Follow the below steps to install the stable release from the Optimum Habana examples and library:
Clone the Optimum-Habana project to access the examples that are optimized for Gaudi:
cd ~ git clone https://github.com/huggingface/optimum-habana.git cd optimum-habana git checkout 1.10.4
Install Optimum-Habana library. This will install the latest stable release:
pip install optimum-habana==1.10.4
In order to use the DeepSpeed library on Gaudi 2, install the Intel Gaudi DeepSpeed fork:
pip install git+https://github.com/HabanaAI/[email protected]
The following example is based on Optimum-Habana Text Classification task example. Change to the text-classification directory and install the additional SW requirements for this specific example:
cd ~
cd optimum-habana/examples/text-classification/
pip install -r requirements.txt
Now your system is ready to execute fine-tuning on a BERT-Large model.
Execute Single-Card Training¶
In the ~/optimum-habana/examples/text-classification/ folder, copy and paste the following commands to your terminal window
to fine-tune the BERT-Large Model on one Gaudi card:
python run_glue.py \
--model_name_or_path bert-large-uncased-whole-word-masking \
--gaudi_config_name Habana/bert-large-uncased-whole-word-masking \
--task_name mrpc \
--do_train \
--do_eval \
--per_device_train_batch_size 32 \
--learning_rate 3e-5 \
--num_train_epochs 3 \
--max_seq_length 128 \
--output_dir ./output/mrpc/ \
--use_habana \
--use_lazy_mode \
--bf16 \
--use_hpu_graphs_for_inference \
--throughput_warmup_steps 3
The results will show both training and evaluation:

Execute Multi-Card Training¶
In this example, you will be doing the same fine-tuning task on eight Gaudi 2 cards. Copy and paste the following into the terminal window:
python ../gaudi_spawn.py --world_size 8 --use_mpi run_glue.py \
--model_name_or_path bert-large-uncased-whole-word-masking \
--gaudi_config_name Habana/bert-large-uncased-whole-word-masking \

Training with DeepSpeed¶
With the DeepSpeed package already installed, run multi-card training with DeepSpeed. Create and point
to a ds_config.json file to set up the parameters of the DeepSpeed run. See the Hugging Face GitHub page
and copy the configuration file example. Once the ds_config.json file is created, copy and paste these instructions into your terminal:
python ../gaudi_spawn.py \
--world_size 8 --use_deepspeed run_glue.py \
--model_name_or_path bert-large-uncased-whole-word-masking \
--gaudi_config_name Habana/bert-large-uncased-whole-word-masking \
--task_name mrpc \
--do_train \
--do_eval \
--per_device_train_batch_size 32 \
--per_device_eval_batch_size 8 \
--learning_rate 3e-5 \
--num_train_epochs 3 \
--max_seq_length 128 \
--output_dir /tmp/mrpc_output/ \
--use_habana \
--use_lazy_mode \
--use_hpu_graphs_for_inference \
--throughput_warmup_steps 3 \
--deepspeed ds_config.json
To learn more about DeepSpeed, refer to the DeepSpeed User Guide for Training.
Inference Example Run¶
Using inference will run the same evaluation metrics (accuracy, F1 score) as shown above. This will display how well the model has performed:
python run_glue.py --model_name_or_path bert-large-uncased-whole-word-masking \
--gaudi_config_name Habana/bert-large-uncased-whole-word-masking \
--task_name mrpc \
--do_eval \
--max_seq_length 128 \
--output_dir ./output/mrpc/ \
--use_habana \
--use_lazy_mode \
--use_hpu_graphs_for_inference
You have now run training and inference on Gaudi 2 using the Intel Developer Cloud.
Next Steps¶

To run more examples using Hugging Face go here.
To migrate other models to Gaudi 2, refer to PyTorch Model Porting.
Setting up Multiple Gaudi Nodes¶
Follow these steps to manually set up a multi-node environment. This example shows how to set up two Gaudi nodes on the Intel Developer Cloud.
Initial Setup¶
These generic instructions should be set for any platform:
Make sure CPUs on the node are set to performant mode:
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
Set the Hugepages on all hosts to enable models:
sudo sysctl -w vm.nr_hugepages=150000 cat /proc/meminfo | grep HugePages_Total | awk '{ print $2 }'
Make sure all external ports are set to ON for each host:
/opt/habanalabs/qual/gaudi2/bin/manage_network_ifs.sh --status /opt/habanalabs/qual/gaudi2/bin/manage_network_ifs.sh --up
(Optional) Generate an
/etc/gaudinet.jsonfile for L3 base scaling. This is not required for L2 based scaling. For this two-node example, this file is not needed.
Get the Host IP Address¶
You will need the IP Addresses of all the nodes in the cluster. From the “My Instances” window, you can see each Host IP address for each node. In the example below, the IP Address is 100.80.239.155. You will need to collect the IP Addresses of all your configured nodes:
Test Using HCCL_demo¶
Running the HCCL_demo tests basic node to node communications. The first run tests each node individually, and the second uses both nodes together.
Set up the test:
cd /root git clone https://github.com/HabanaAI/hccl_demo.git cd hccl_demo/ make clean
Run the first test - a single run using the below command on both nodes individually:
HCCL_COMM_ID=127.0.0.1:5555 python3 run_hccl_demo.py --nranks 8 --node_id 0 --size 256m --test all_reduce --loop 1000 --ranks_per_node 8
Run the second test - run two node hccl-demo. Make sure to replace the
{IP_ADDRESS_NODE0}and{IP_ADDRESS_NODE1}in the commands below with the actual IP addresses of your nodes:python3 run_hccl_demo.py --test all_reduce --loop 1000 --size 32m -mpi --host {IP_ADDRESS_NODE0}:8,{IP_ADDRESS_NODE1}:8 --mca btl_tcp_if_include ens7f1
Test Using DeepSpeed¶
The next test uses the LLaMA 13B model from Megatron-DeepSpeed GitHub repository.
Prepare a shared directory accessible to all the nodes and clone the Model-References repository to the shared directory from one node:
cd /shared_dir git clone https://github.com/HabanaAI/Megatron-DeepSpeed.gitSet up the environment variables and install necessary modules on all the nodes:
cd /shared_dir/Megatron-DeepSpeed export MEGATRON_DEEPSPEED_ROOT=/path/to/Megatron-DeepSpeed export PYTHONPATH=$MEGATRON_DEEPSPEED_ROOT/:$PYTHONPATH pip install -r megatron/core/requirements.txt pip install git+https://github.com/HabanaAI/[email protected] apt update apt install pdsh -y
Update the IP addresses in the hostfile. Edit the
scripts/hostsfileand modify the two IP addresses with the ones from your nodes.Follow the Dataset Preparation instructions to acquire the full oscar-en dataset. Or, apply the following steps from one node to create a customized and smaller RedPajama dataset to check the connectivity among nodes:
mkdir -p /shared_dir/redpajama cd /shared_dir/redpajama # download the redpajama dataset list file and merely pick the first jsonl, which is arxiv wget 'https://data.together.xyz/redpajama-data-1T/v1.0.0/urls.txt' head -n 1 urls.txt > first_jsonl.txt while read line; do dload_loc=${line#https://data.together.xyz/redpajama-data-1T/v1.0.0/} mkdir -p $(dirname $dload_loc) wget "$line" -O "$dload_loc" done < first_jsonl.txt cd arxiv # download the vocabulary and merge files to tokenize the input text wget https://s3.amazonaws.com/models.huggingface.co/bert/gpt2-vocab.json wget https://s3.amazonaws.com/models.huggingface.co/bert/gpt2-merges.txt # install necessary modules for data preparation pip install nltk sentencepiece python $MEGATRON_DEEPSPEED_ROOT/tools/preprocess_data.py --input *.jsonl --output-prefix meg-gpt2 --vocab-file gpt2-vocab.json --merge-file gpt2-merges.txt --append-eod --tokenizer-type GPT2BPETokenizer --workers 64 # use the tokenized files from above step to train
Choose the expected dataset and run the below command from one node:
cd $MEGATRON_DEEPSPEED_ROOT mkdir -p out_llama DATA_DIR_ROOT=/data/pytorch/megatron-gpt/oscar-en # DATA_DIR_ROOT=/shared_dir/redpajama/arxiv HL_RESULTS_DIR=out_llama HL_DATA_DIR_ROOT=$DATA_DIR_ROOT HL_HOSTSFILE=scripts/hostsfile HL_NUM_NODES=2 HL_PP=2 HL_TP=2 HL_DP=4 scripts/run_llama.sh
