Overview

This repository contains a representative subset of the first-party DNN training workloads on Microsoft's internal Philly clusters. The trace is a sanitized subset of the workload described in "Analysis of Large-Scale Multi-Tenant GPU Clusters for DNN Training Workloads" in ATC’19. This work was done as part of Microsoft Research's Project Fiddle.

We include in this repository a jupyter notebook that highlights the main characteristics of the traces and shows how to parse them (a huge thank you to Keshav Santhanam for putting this together).

We provide the trace as is. If you do use this trace in your research, please make sure to cite our ATC’19 paper (mentioned above).

List of keys:

• status: The job's status upon completion. One of Pass, Killed, or Failed.
• vc: The hash of the virtual cluster the job was run in.
• jobid: The id of the job.
• attempts: A list of dicts where each dict has the following keys:
  • start_time: The start time of the attempt.
  • end_time: The end time of the attempt.
  • detail: A list of dicts where each dict has the following keys:
    • ip: The id of the server the attempt was scheduled on.
    • gpus: A list of GPUs used by the attempt.
• submitted_time: The time the job was submitted to the scheduler.
• user: A hash of the user id.

Notes:

• A job may have no recorded scheduling attempts.
• A scheduling attempt may have no recorded start_time and/or end_time - this could be the result of a logging error.
• If a job has a None value for its last attempt's end_time, the job was still running at the time the snapshot was taken.
