[gpfsug-discuss] Call for Submission for the IO500 List

[George Markomanolis]

Call for Submission

*Deadline*: 10 November 2019 AoE

The IO500 <http://io500.org/> is now accepting and encouraging submissions
for the upcoming 5th IO500 list revealed at SC19 in Denver, Colorado. Once
again, we are also accepting submissions to the 10 Node I/O Challenge to
encourage submission of small scale results. The new ranked lists will be
announced at our SC19 BoF [2]. We hope to see you, and your results, there.
We have updated our submission rules [3]. This year, we will have a new
list for the Student Cluster Competition as IO500 is used for extra points
during this competition

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 SC19! Please note that
submissions of all sizes 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
<http://io500.org/> was created in 2017, published its first list at SC17,
and has grown exponentially since then. 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:

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 have historically
not been well-measured. Submitters are encouraged to share their tuning
insights for publication.

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
10 Node I/O Challenge

At SC, we will continue the 10 Node Challenge. This challenge is conducted
using the regular IO500 benchmark, however, with the rule that exactly *10
computes nodes* must be used to run the benchmark (one exception is the
find, which may use 1 node). You may use any shared storage with, e.g., any
number of servers. We will announce the result in a separate derived list
and in the full list but not on the ranked IO500 list at io500.org.
Birds-of-a-feather

Once again, we encourage you to submit [1], to join our community, and to
attend our BoF “The IO500 and the Virtual Institute of I/O” at SC19,
November 19th, 12:15-1:15pm, room 205-207, where we will announce the new
IO500 list, the 10 node challenge list, and the Student Cluster Competition
list. We look forward to answering any questions or concerns you might have.
