Submit your IO500 results for the upcoming SC'26 list, which will be presented at our BOF. See the Call for Submissions for details.

Historical SC19 List

This is the historic data list released at Supercomputing 2019. Since the IO500 benchmark has been improved to reduce the opportunity of caching, some results of the former lists cannot be directly compared to the new results. The list shows all submissions up to now.
