This page contains the information about the submission procedure. First, you need to run the benchmark .

The IO500 list is released during ISC and SC. See our call for submissions page for details. Submissions to the upcoming list can be made all year. However, to be included in the next submission, we must receive the submission before the deadline listed in our call for submissions.

Submission Instructions

There are two options to submit to the IO500, we prefer the online form:

  1. Use our online form. You have to receive a one-time token (please check your SPAM folder if you did not receive the initial response 5 minutes later).
  2. If you experience any problems with the online form; send an email with attachments:
    • The (potentially) adapted
    • The output directory of the benchmark (variable io500_result_dir in
    • If possible, please mention which system is covered of the CDCL or provide system information such that we can add the system to the CDCL!

We will reply to you, to confirm reception and any question that may arise.

Handling of the Submitted Data

Until the next release of the list, the submission committee will handle all submitted data confidentially. That means that we will not disclose any submitted data to individuals/companies, or institutions.


We will publish all data submitted, so by submitting the information you give us the right to publish the uploaded data.

Submitter Name

Submissions will be visible immediately to the members of the IO500 Steering Committee. If there is sensitivity about early visibility to your results being seen by any of the committee, please feel free to email results privately to a subset of the committee (i.e. do not use the official submission tools if you have privacy concerns).

Starting with the SC'18 list, submissions include the name of the submitter (or team) to give them the credit they deserve to execute the benchmark; this can be opted out.


With the online form, the submitter is able to individually opt-out the submission the name of the submitter/team (this will be then an anonymous submission)
