Purpose The purpose of this paper is to investigate the prospects of current storage
technologies for long-term preservation of big data in digital libraries. Design/methodology …

Recent studies have shown that moderate to high data redundancy exists in primary storage
systems, such as VM-based, enterprise and HPC storage systems, which indicates that the …

The demand for data storage and processing is increasing at a rapid speed in the big data
era. Such a tremendous amount of data pushes the limit on storage capacity and on the …

Increasingly, large-scale computing systems are consuming more power each passing year.
As power consumption is on the rise, concern has been raised over the growing implications …

The demand for data storage and processing is increasing at a rapid speed in the big data
era. The management of such tremendous volume of data is a critical challenge to the data …

Long-running HPC applications guard against node failures by writing checkpoints to
parallel file systems. Writing these checkpoints with petascale class machines has proven …

System provisioning, resource allocation, and system configuration decisions for I/O-
intensive workflow applications are complex even for expert users. Users face choices at …

We present here the ExM (extreme-scale many-task) programming and execution model as
a practical solution to the challenges of programing the higher-level logic of complex parallel …

Energy efficiency of storage system is an important research topic as it largely affects the
energy consumption of data centers. Although the technology of deduplication can save …

Contemporary software systems are often highly configurable and additionally they change
over time (evolve). These changes do not only affect the functionality but also non-functional …
