Analyzing Parallel I/O

SESSION: Analyzing Parallel I/O

EVENT TYPE: Birds of a Feather

EVENT TAG(S): Storage, Analytics

TIME: 1:30PM - 3:00PM

SESSION LEADER(S):Julian M. Kunkel, Philip Carns



Parallel application I/O performance often does not meet user expectations. Additionally, slight access pattern modifications may lead to significant changes in performance due to complex interactions between hardware and software. These challenges call for sophisticated tools to capture, analyze, understand, and tune application I/O.

In this BoF, we will highlight recent advances in monitoring tools to help address this problem. We will also encourage community discussion to compare best practices, identify gaps in measurement and analysis, and find ways to translate parallel I/O analysis into actionable outcomes for users, facility operators, and researchers.
