BoF: Analyzing Parallel I/O
Abstract
Parallel I/O performance can be a critical bottleneck for applications, yet users are often ill-equipped for identifying and diagnosing I/O performance issues. Increasingly complex hierarchies of storage hardware and software deployed on many systems only compound this problem. Tools that can effectively capture, analyze, and tune I/O behavior for these systems empower users to realize performance gains for many applications.
In this BoF, we form a community around best practices in analyzing parallel I/O and cover recent advances to help address the problem presented above, drawing on the expertise of users, I/O researchers, and administrators in attendance.
The primary objectives of this BoF are to: 1) highlight recent advances in tools and techniques for monitoring I/O activity in data centers, 2) to discuss experiences and limitations of current approaches, 3) to discuss and derive a roadmap for future I/O tools with the goal to capture, assess, predict and optimize I/O.
The BoF is held in conjunction with the Supercomputing conference. The official announcement is listed here.
