IO500 Call for Submissions
Deadline: 23 June 2018 AoE

The IO500 is now accepting and encouraging submissions for the upcoming
IO500 list revealed at ISC 2018 in Frankfurt, Germany. The benchmark suite
is designed to be easy to run and the community has multiple active support
channels to help with any questions. Please submit and we look forward to
seeing many of you at ISC 2018! Please note that submissions of all size
are welcome; the site has customizable sorting so it is possible to submit
on a small system and still get a very good per-client score for example.
Additionally, the list is about much more than just the raw rank; all
submissions help the community by collecting and publishing a wider corpus
of data. More details below.

Following the success of the Top500 in collecting and analyzing historical
trends in supercomputer technology and evolution, the IO500 was created in
2017 and published its first list at SC17. The need for such an initiative
has long been known within High Performance Computing; however, defining
appropriate benchmarks had long been challenging. Despite this challenge,
the community, after long and spirited discussion, finally reached
consensus on a suite of benchmarks and a metric for resolving the scores
into a single ranking.

The multi-fold goals of the benchmark suite are as follows:

* Maximizing simplicity in running the benchmark suite
* Encouraging complexity in tuning for performance
* Allowing submitters to highlight their “hero run” performance numbers
* Forcing submitters to simultaneously report performance for challenging
IO patterns.

Specifically, the benchmark suite includes a hero-run of both IOR and
mdtest configured however possible to maximize performance and establish an
upper-bound for performance. It also includes an IOR and mdtest run with
highly prescribed parameters in an attempt to determine a lower-bound.
Finally, it includes a namespace search as this has been determined to be a
highly sought-after feature in HPC storage systems that has historically
not been well-measured. Submitters are encouraged to share their tuning
insights for publication.

The goals of the community are also multi-fold:

* Gather historical data for the sake of analysis and to aid predictions of
storage futures
* Collect tuning information to share valuable performance optimizations
across the community
* Encourage vendors and designers to optimize for workloads beyond “hero
runs”
* Establish bounded expectations for users, procurers, and administrators

Once again, we encourage you to submit (see http://io500.org/submission),
to join our community, and to attend our BoF “The IO-500 and the Virtual
Institute of I/O” at ISC 2018 where we will announce the second ever IO500
list. The current list includes results from BeeGPFS, DataWarp, IME,
Lustre, and Spectrum Scale. We hope that the next list has even more!

We look forward to answering any questions or concerns you might have.

Thank you!

IO500 Committee
