Abstract: The last few decades have witnessed an unprecedented growth in the computational power of supercomputers. Exploiting the full capabilities of these machines is becoming exponentially more difficult with each new generation of hardware. To help understand and optimize the behavior of parallel applications running on such hardware, the performance analysis community has created a wide range of tools and APIs to collect performance data, such as hardware counters, communication traces, and network traffic data. This success has created a new challenge: the resulting data is far too large and too complex to be analyzed in a straightforward manner. Therefore, new automatic analysis and visualization approaches must be developed to enable application developers to intuitively understand the multiple, interdependent effects that their algorithmic choices have on application performance. This workshop intends to bring together researchers from the fields of performance analysis and visualization for a continued exchange of new approaches to leverage both areas to analyze and optimize large-scale parallel applications.
