Dear all,
please see the call for submission for the IO-500 at ISC-HPC below.
We are interested in short talks for the Birds-of-a-feather session,
so if you have something interesting, please get in touch with us.
Best,
The IO-500 Steering Committee.
# Deadline: 10 June 2019 AoE
The IO500 is now accepting and encouraging submissions for the
upcoming 4th IO500 list revealed at ISC-HPC 2019 in Frankfurt,
Germany. Once again, we are also accepting submissions to the 10 node
I/O challenge to encourage the submission of small scale results. The
new ranked lists will be announced at our ISC19 BoF [2]. We hope to
see you, and your results, there.
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 2019!
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, 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:
* 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
## 10 Node I/O Challenge
At ISC, we will announce our second IO-500 award for the 10 Node
Challenge. This challenge is conducted using the regular IO-500
benchmark, however, with the rule that exactly 10 computes nodes must
be used to run the benchmark (one exception is find, which may use 1
node). You may use any shared storage with, e.g., any number of
servers. When submitting for the IO-500 list, you can opt-in for
“Participate in the 10 compute node challenge only”, then we won't
include the results into the ranked list. Other 10 compute node
submission will be included in the full list and in the ranked list.
We will announce the result in a separate derived list and in the full
list but not on the ranked IO-500 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 IO-500 and the Virtual Institute of I/O” at ISC
2019 [2] where we will announce the fourth IO500 list and second 10
node challenge list. The current list includes results from BeeGPFS,
DataWarp, IME, Lustre, Spectrum Scale, and WekaIO. We hope that the
next list has even more.
We look forward to answering any questions or concerns you might have.
