 +====== Workshop: Understanding I/O Performance Behavior (UIOP) ======
 +
 +Understanding I/O performance behavior is crucial to optimize I/​O-intensive 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 performance.
 +
 +The main goal of the workshop is the 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 enable 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.

 +
 +It is embedded into a joint cooperation workshop between [[https://​www.dkrz.de/​Nutzerportal-en/​workshops/​jamstec-dkrz-WS17|DKRZ and JAMSTEC]].
 +
 +
 +===== Organization =====
 +
 +The workshop is organized by 
 +  * Julian Kunkel (DKRZ), [[kunkel@dkrz.de]]
 +  * Tsuyoshi Nakagawa (JAMSTEC), [[tnakagawa@jamstec.go.jp]]
 +  * Jay Lofstead (Sandia National Laboratory),​ [[jay gflofst@sandia.gov]]
 +
 +===== Registration =====
 +
 +To participate,​ please register online (the deadline is now over). Alternatively,​ you may send an email to [[kunkel@dkrz.de]].
 +The deadline for registration is Feb. 25th.
 +Note that our seats are limited and we have to confirm your attendance (you may also kindly ask about the status).
 +===== Accommodation =====
 +
 +Within walking distance, we recommend the: [[http://​www.mercure.com/​en/​hotel-5394-mercure-hotel-hamburg-mitte/​index.shtml|Mercure Hotel Hamburg Mitte]] \\
 +Address: Schroederstiftstr. 3, 20146 Hamburg - Rotherbaum, Deutschland
 +
 +DKRZ has a customer ID that we can provide to you upon request; this should give you a condition of 79€ per night.
 +
 +===== Agenda =====
 +
 +The workshop is scheduled for a duration of one day, with discussion time between talks -- directly followed by another workshop (to be announced). ​
 +It is intended to use the workshop to foster the international collaboration for the IO-500 list, i.e., the definition of a meaningful I/O benchmark for tracking storage performance for current and future systems.
 +
 +The Agenda is currently in preparation.
