Announce New VM Rule
by John Bent
To IO500 Community,
The committee has received some queries about the rules concerning virtual
machines for the 10 Node Challenge. As such, the committee has added the
following rule:
13. For the 10 Node Challenge, there must be exactly 10 physical nodes for
client processes and at least one benchmark process must run on each
1.
Virtual machines can be used but the above rule must be followed. More
than one virtual machine can be run on each physical node.
Although we recognize that this may disadvantage cloud architectures, we do
want to stress that this rule only applies to the 10 Node Challenge. The
committee did feel it was important to add this rule to ensure that the 10
Node Challenge sublist offers the maximum potential for fair comparisons by
ensuring equivalent client hardware quantities. Submissions with any
number/combination of virtual and physical machines can of course always be
submitted to the full list.
Thank you,
The IO500 Committee

Call for Submission for the IO500 List

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 nodesmust 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 <http://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.
