Burst buffers are becoming an indispensable hardware resource on large-scale
supercomputers to buffer the bursty I/O from scientific applications. However, there is a lack …

When complex systems are constructed from simpler components it is important to know
how properties of the components behave under composition. We present various …

Hierarchical storage subsystems that include multiple layers of burst buffers (BB) and disk-
based parallel file systems (PFS), are becoming an essential part of HPC systems to …

Data staging and in-situ workflows are being explored extensively as an approach to
address data-related costs at very large scales. However, the impact of emerging storage …

Storage backends of parallel compute clusters are still based mostly on magnetic disks,
while newer and faster storage technologies such as flash-based SSDs or non-volatile …

Scientific data sets, which grow rapidly in volume, are often attached with plentiful metadata,
such as their associated experiment or simulation information. Thus, it becomes difficult for …

High performance computing (HPC) architectures have been adding new layers of storage,
such as burst buffers, to tolerate latency between memory and disk-based file systems …

Machine learning (ML) is being applied in a number of everyday contexts from image
recognition, to natural language processing, to autonomous vehicles, to product …

Concurrent accesses to the shared storage resources in current HPC machines lead to
severe performance degradation caused by I/O contention. In this study, we identify some …

In this work, we investigate the problem of inter-application interference in a shared Burst
Buffer (BB) system. A BB is a new storage technology for HPC architectures that acts as an …
