as mentioned before, to foster the benchmarking effort we are
organizing a workshop about the "understanding of I/O performance
behavior" on March 23rd and 24th in 2017 that takes place at DKRZ,
Hamburg and invite each of you to participate in this workshop and (if
you are interested) give a talk related to this topic.
Of course you can participate as regular attendee without giving a talk, too.
Please fill the form to indicate your interest in the workshop and
optionally a preliminary title:
== Abstract ==
Understanding I/O performance behavior is crucial to optimize
I/O-intense applications but also the infrastructure of data centers.
However, with the dawn of new technologies such as NVRAM,
burst-buffers, active storage/function shipping, and network attached
memory, the complexity of storage infrastructure increases
significantly and the boundary between memory and storage blurs.
During the procurement of new systems, data centers have to ensure
that the application's needs are met. Therefore, they need to define
the proper requirements for storage and provide I/O benchmarks that
represent application workloads to quantify and verify I/O
The main goal of the workshop is discussion of tools to identify
(in-)efficient usage of I/O resources on modern storage subsystems
from the perspective of users and data centers.
The workshop covers:
a discussion of design alternatives of storage architectures and their
implications on user workflows;
telemetry and monitoring information necessary to understand actual
rather than reported I/O activity enabling efficient performance
optimization of system and applications;
the development of representative benchmarks resembling the applications' needs.
The discussion of alternative storage architectures lays the
foundation for the requirements of the monitoring and benchmarking
efforts. Speakers involved in storage and file system research will
present experience in alternative storage architectures, application
workflows, monitoring tools to identify bottlenecks in I/O, and
(benchmarking) tools to quantify I/O performance. Scientists involved
in various application domains can give an introduction to their
workflows and I/O requirements.
By bringing together application developers/users and I/O experts, we
support the development of tools to identify and quantify I/O
inefficiencies that support users and data centers.
