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

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

1. Maximizing simplicity in running the benchmark suite

2. Encouraging complexity in tuning for performance

3. Allowing submitters to highlight their "hero run" performance numbers

4. 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

The goals of the community are also multi-fold:

1. Gather historical data for the sake of analysis and to aid
predictions of storage futures

2. Collect tuning information to share valuable performance
optimizations across the community

3. Encourage vendors and designers to optimize for workloads beyond “hero runs”

4. Establish bounded expectations for users, procurers, and administrators

Once again, we encourage you to submit (see, 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.

The first list unfortunately had no submission from OrangeFS, we hope
to see some submissions this time!

Thank you!
