  9. Overview of distributed training Install software and containers Schedule jobs Provision clusters of VMs Share results Distribute data Scale resources Handling failures Mathew Salvaris (@msalvaris) – Ilia Karmanov (@ikdeepl) – Miguel Fierro (@miguelgfierro)

  10. Azure Distributed Platforms ▪ Batch AI ▪ Batch Shipyard ▪ DL Workspace Horovod Mathew Salvaris (@msalvaris) – Ilia Karmanov (@ikdeepl) – Miguel Fierro (@miguelgfierro)

  11. Batch Shipyard • Supports Docker and Singularity: run your Docker and Singularity containers within the same job, side-by-side or even concurrently • Move data easily between locally accessible storage systems, remote filesystems, Azure Blob or File Storage, and compute nodes • Supports local storage, Azure Blob or File Storage, and NFS. • Low priority nodes https://github.com/Azure/batch-shipyard Mathew Salvaris (@msalvaris) – Ilia Karmanov (@ikdeepl) – Miguel Fierro (@miguelgfierro)

  12. Batch AI • Supports running on Docker container as well as the Data Science Virtual Machine • Supports local storage, Azure Blob or File Storage, and NFS. • Low priority nodes https://github.com/Azure/BatchAI Mathew Salvaris (@msalvaris) – Ilia Karmanov (@ikdeepl) – Miguel Fierro (@miguelgfierro)

  13. DL Workspace • Runs jobs inside Docker • Uses Kubernetes • Can be deployed anywhere not just Azure • Supports local storage and NFS https://github.com/Microsoft/DLWorkspace Mathew Salvaris (@msalvaris) – Ilia Karmanov (@ikdeepl) – Miguel Fierro (@miguelgfierro)

  14. Training with Batch AI 1) Create scripts to run on Batch AI 1 and transfer them to file storage I 2) Write the data to storage A I 2 3) Create the docker containers for each DL framework and transfer them to a container registry 3 Mathew Salvaris (@msalvaris) – Ilia Karmanov (@ikdeepl) – Miguel Fierro (@miguelgfierro)

  15. 1) Create a Batch AI Pool I A I 2 2) Each job will pull in the 2 appropriate container, script and 1 Batch AI Pool load data from chosen storage 3) Once the job is completed all the 2 results will be written to the fileshare 3 Mathew Salvaris (@msalvaris) – Ilia Karmanov (@ikdeepl) – Miguel Fierro (@miguelgfierro)
