The 6th HPC I/O in the Data Center Workshop (HPC-IODC 2020) in conjunction with
ISC High Performance on Thursday, June 25th, 2020, in Frankfurt, Germany.

== Workshop overview ==

Managing scientific data at a large scale is challenging for scientists
but also for the host data center. The storage and file systems
deployed within a data center are expected to meet users' requirements
for data integrity and high performance across heterogeneous and
concurrently running applications.

With new storage technologies and layers in the memory hierarchy, the picture is
becoming murkier. To effectively manage the data load within a data center, I/O
experts must understand how users expect to use these new storage technologies
and what services they should provide in order to enhance user productivity.
We seek to ensure a systems-level perspective is included in these discussions.

In this workshop, we bring together I/O experts from data centers and
Application workflows to share current practices for scientific workflows, issues and
obstacles for both hardware and the software stack, and R&D to overcome these
issues.

The workshop content is built on two tracks:
1) research paper track – requesting submissions regarding state-of-the-practice
and research about I/O in the datacenter.
2) talks from I/O experts – you'll need to submit an abstract for your talk.

Contributions to both tracks are peer-reviewed and require submission of the
respective research paper or idea for your presentation via Easychair:
https://easychair.org/conferences/?conf=hpciodc20

== Track: research papers ==

We are excited to announce that research papers will be published in Springer
Lecture Notes of Computer Science (LNCS) series and extended manuscripts in the new open-access Journal of High-Performance Storage (https://jhps.vi4io.org/) as well.

The research track accepts papers covering state-of-the-practice and research dedicated to storage in the datacenter. We accept papers with up to 12 pages (excl. references) in LNCS format.

For accepted papers, the length of the talk during the workshop
depends on the controversiality and novelty of the approach (the
length is decided based on the preference provided by the authors and
feedback from the reviewers). We also allow virtual participation
(without attending the workshop personally). All relevant work in the
area of data center storage will be able to publish with our joint
workshop proceedings, we just believe the available time should be
used best to discuss controversial topics.

=== Topics ===
The relevant topics for papers cover all aspects of data center I/O including:
* application workflows
* user productivity and costs
* performance monitoring
* dealing with heterogeneous storage
* data management aspects
* archiving and long term data management
* state-of-the-practice (e.g., using or optimizing a storage system
for data center workloads)
* research that tackles data center I/O challenges

=== Paper Deadlines ===
* Submission deadline: 2020-02-24 AoE
* Author notification: 2020-04-24
* Pre-final submission: 2020-06-10
* Workshop: 2020-06-25

== Track: Talks by I/O experts ==

The topics of interest in this track include but are not limited to:
* A description of the operational aspects of your data center
* A particular solution for certain data center workloads in production

We also accept industry talks, given that they focus on operational issues
and omit marketing.

If you are interested to participate, please submit a short (1/2 page) abstract
of your talk together with a (very) short Bio.

Abstract Deadlines:
* Submission deadline: 2020-04-10 AoE
* Author notification: 2020-05-03
