IO500 SC18* List

This is an intermediate list based on corrected calculations1 for the IO-500 ranked list2 from November 2018 (from SC 2018).

To cite this list, please use this bibtex.

Please see also the 10 node challenge ranked list.

The list shows the best result for a given combination of system/institution/filesystem.

1We fixed the computation of the mdtest score that had a bug by computing the rate using the external measured timing.

2That means only those entries that qualify according to the wish of the submitter are contained.
