2009 Parallel, Distributed and Network-based Processing
Verifying Causality between Distant Performance Phenomena in Large-Scale MPI Applications
Weimar, Germany
February 18-February 20
ISBN: 978-0-7695-3544-9
In message-passing applications, the temporal or spatial distance between cause and symptom of a performance problem constitutes a major difficulty in deriving helpful conclusions from performance data. Just knowing the locations of wait states in the program is often insufficient to understand the reason for their occurrence.
