GPT-home-private

Setup:

• Use AWS Deep Learning Base AMI

• Install PyTorch env:

  pip3 install torch==1.9.0+cu111 torchtext -f https://download.pytorch.org/whl/torch_stable.html
  pip3 install torch==1.9.0+cu111 -f https://download.pytorch.org/whl/torch_stable.html
  pip install torch==1.10.1+cu111 -f https://download.pytorch.org/whl/torch_stable.html
  
  # Magic, not sure why cupy-cuda111 would not work, it seems that cupy-cuda111 will use different PTX from torch.
  pip3 install cupy-cuda111==8.6.0
  
  pip3 install transformers
  

• Install deepspeed for some micro-benchmark (optional)

  pip install deepspeed
  

• Clone this repo:

  git clone https://github.com/BinhangYuan/GPT-home-private.git
  

• set the github cache (Optional):

  git config credential.helper 'cache --timeout=30000'
  

• Download a tiny dataset:

  wget https://binhang-language-datasets.s3.us-west-2.amazonaws.com/glue_qqp_dataset/data.tar.xz -P ./glue_dataset/
  
  tar -xvf ./glue_dataset/data.tar.xz -C ./glue_dataset/
  

• Setup network configuration:

  export GLOO_SOCKET_IFNAME=ens3
  
  export NCCL_SOCKET_IFNAME=ens3
  

• Use TC scripts to control network delay and bandwidth:

Run Distributed Gpipe:

• On each node, run:

  python dist_pipeline_runner.py --dist-url tcp://XXX.XXX.XXX.XXX:9000 --world-size N --rank i (i=0,...,N-1)
  

Run deepspeed benchmark:

• Update public-ip and hostname in the ./scripts/ip_list.sh file

• Update the host name with slots (number of GPUs) in ./scripts/ds_hostnames.sh file

• Sync code to all nodes

• Setup password free ssh cluster by executing (under the ./script/ directory):

  bash ssh_pass_free.sh
  

• SSH to the rank-0 node, on that node run:

  source activate pytorch_p38
  

• A sample run:

  deepspeed --hostfile=./scripts/ds_hostnames dist_deepspeed_zero_s3.py --embedding-dim 2048 --seq-length 2048 --batch-size 1024 --num-layers 40 --micro-batch-size 4
  

• Batch run all settings:

   cd ./scripts
   bash local_run_deepspeed_batch_on_rank0.sh #CASE
  

Run with Advanced Scripts (under scripts directory):

• First update the public IPs and private IP of the rank-0 node in ip_list.sh.

• Allow SSH connects:

  bash accept_ssh_keys.sh
  

• Update local repository:

  bash aws_sync_code.sh #GIT_TOKEN
  

• Enable environment: (This is optional but load conda env seems to be slow for the first time)

  bash aws_foo_load_lib.sh
  

• Setup heterogeneous network (update the private IPs in ./scheduler/generate_heterogeneous_tc.py, sync the code to AWS!):

  bash aws_generate_heter_tc.sh #HETER_CASE (3/4/5)
  

• Optional(Play with it by starting TC, this is not needed if you use the next block of cmds to start benchmarks):

  bash aws_start_heter_tc.sh #HETER_CASE (3/4/5)
  

• Run Schedulers (under scheduler/heuristic_evolutionary_solver directory) to get assignments and estimated cost

  python scheduler.py
  

• Update correspond aws_run_gpt3_*_training.sh with the above output:

• Run Tasks (e.g.,):

  bash aws_run_gpt3_training.sh gpt3_small_pp3_dp4.sh
  bash aws_run_gpt3_training.sh gpt3_small_pp3_dp4.sh #HETER_CASE
  bash aws_run_gpt3_training.sh gpt3_small_pp3_dp4.sh #DELAY #BANDWIDTH
  

• Clear logs:

  bash aws_clear_logs.sh
  

• Copy training logs from Rank-0 node (For my implementation the benchmark result is on the rank-0 node.)

  bash copy_rank0_logs.sh
  

• Download and generate trace:

  bash copy_traces.sh #PREFIX
  bash generate_traces.sh #PREFIX
  

Run the System on Euler with Coordinator

• First log in to ETH Zurich Euler cluster (need to use VPN if not on campus), our working directory:

  /nfs/iiscratch-zhang.inf.ethz.ch/export/zhang/export/fm/
  

• Get the Euler ssh client's node IP, and start the coordinator server (under ./coordinator directory), e.g.:

  python coordinate_server.py --coordinator-server-ip 129.132.93.88 --coordinator-type inference/train
  

• Alternatively, we can use the following script to submit multiple jobs:

  bash multi_inference_jobs_submit.sh 129.132.93.88 lsf_gptJ_inf_4RTX2080Ti 3 10
  

• On a different terminal, start a job submission client to submit a job:

  python job_submit_client.py --coordinator-server-ip 129.132.93.88 --submit-job inference --job-name lsf_gptJ_inf_4RTX2080Ti
  

• So far, we need to manually change the IP in the job-submit templates, e.g. change lsf_gptJ_inf_4gpu.bsub file.

• Check submitted job states:

  bjobs
