Call for Submission
Stabilization Period: Monday, April 1st - Friday, April 15th, 2024
Submission Deadline: Tuesday, May 3rd, 2024 AoE
The IO500 is now accepting and encouraging submissions for the upcoming
14th semi-annual IO500 Production and Research lists, in conjunction
with ISC24. Once again, we are also accepting submissions to both the
Production and Research 10 Client Node Challenges to encourage the
submission of small scale results. View the requirements for submitting
to each list on the IO500 Webpage. The new ranked lists will be
announced at the BoF [1]. We hope to see many new results.
Background
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
continually since then. The benchmarks represent community accepted
standards, including being used in Request for Proposals for new HPC
platforms. The benchmarks showcase the IO access pattern extremes giving
a full picture of storage system potential performance. 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.
The multi-fold goals of the benchmark suite are as follows:
- Represent naive and optimized access patterns for the execution of a
rich variety of HPC applications, their achievable performance and the
documentation of how the numbers are achieved.
- Support small to extreme-scale Research and Production HPC systems
using flexible storage APIs
- Maximizing simplicity in running the benchmark suite while offering
tunable parameters
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 runs with highly
prescribed parameters in an attempt to determine a lower performance
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. Supported Storage APIs are
those that are part of IOR and mdtest. Extending these tools with a
public pull request can be done to enable new storage APIs.
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
5. Understand and be able to reproduce performance on storage systems
Using the IO500 Reproducibility guidelines, each submission is labeled
according to the breadth of details provided and the access to the
deployed storage software that enables the community to reproduce the
results and study system design changes over time.
The IO500 follows a two-staged approach. First, there will be a two-week
stabilization period during which we encourage the community to verify
that the benchmark runs properly on a variety of storage systems. During
this period the benchmark may be updated based upon feedback from the
community. The final benchmark will then be released. We expect that
runs compliant with the rules made during the stabilization period will
be valid as a final submission unless a significant defect is found.
10 Client Node I/O Challenge
The 10 Client Node Challenge is conducted using the regular IO500
benchmark, however, with the rule that exactly 10 client nodes must be
used to run the benchmark. You may use any shared storage with any
number of servers. We will announce the results in the Production and
Research lists as well as in separate derived lists.
Birds-of-a-Feather
We encourage you to submit [2] to join our community, and to attend the
ISC’24 BoF [1] on Tuesday, May 12, 2024 at 10:05am - 11:05am CEST, where
we will announce the new IO500 Production and Research lists and their
10 Client Node counterparts.
Be Part of the Community
Submissions of all sizes are welcome; the webpage has customizable
sorting, so it is possible to submit on a small system and still get a
very good per-client score, for example. We will also highlight new and
interesting results with invited talk(s) at the BoF.
