Computational science applications are driving a demand for increasingly powerful storage
systems. While many techniques are available for capturing the I/O behavior of individual …

This paper presents a dynamic, real-time approach to detecting anomalous blockchain
transactions. The proposed tool, BlockGPT, generates tracing representations of blockchain …

The publish/subscribe paradigm is a popular model for allowing publishers (ie, data
generators) to selectively disseminate data to a large number of widely dispersed …

This paper offers a solution to overcome the complexities of production system I/O
performance monitoring. We present Beacon, an end-to-end I/O resource monitoring and …

Evaluation of the behavior of queues with nonstationary arrival processes is of importance in
several applications including communication networks. However, the analysis of …

Standard testing methods of MPI programs do not guarantee coverage of all non-
deterministic interactions (eg, wildcard-receives). Programs tested by these methods can …

The I/O bottleneck in high-performance computing is becoming worse as application data
continues to grow. In this work, we explore how patterns of I/O within these applications can …

Applications must scale well to make efficient use of today's class of petascale computers,
which contain hundreds of thousands of processor cores. Inefficiencies that do not even …

Recorder is a multi-level I/O tracing tool that captures HDF5, MPI-I/O, and POSIX I/O calls. In
this paper, we present a new version of Recorder that adds support for most metadata …

The size of supercomputers in numbers of processors is growing exponentially. Today's
largest supercomputers have upwards of a hundred thousand processors and tomorrow's …
