Performance visualization comprises techniques that aid developers and analysts in
improving the time and energy efficiency of their software. In this work, we discuss …

We present a comprehensive survey on parallel I/O in the high-performance computing
(HPC) context. This is an important field for HPC because of the historic gap between …

As we move toward the exascale era, performance variability in HPC systems remains a
challenge. I/O interference, a major cause of this variability, is becoming more important …

One of the most urgent challenges in event based performance analysis is the enormous
amount of collected data. A real-time event reduction is crucial to enable a complete in …

One of the most urgent issues in event tracing is the number of resulting event trace files
pushing against the limits of today's parallel file systems. To address this issue, we present …

In this paper, we present a diagnosis methodology targeting the whole set of bridging faults
leading to either static or dynamic faulty behavior. The adopted diagnosis algorithm resorts …

Performance analysis tools are more than ever inevitable to develop applications that utilize
the enormous computing resources of high performance computing (HPC) systems. In event …

We argue that memory content-tracking across the nodes of a parallel machine should be
factored into a distinct platform service on top of which application services can be built …

Today, performance analysis of parallel applications is mandatory to fully exploit the
capabilities of modern HPC systems. Many performance analysis tools are available to …

Hardware accelerators have changed the HPC landscape as they open a potential route to
exascale computing. At the same time they also complicate the tasl of application …
