Big data have become a global strategic issue, as increasingly large amounts of
unstructured data challenge the IT infrastructure of global organizations and threaten their …

Recently, Bronson et al. introduced a framework for understanding a class of failures in
distributed systems called metastable failures. The examples of metastable failures …

Crash-recovery bugs (bugs in crash-recovery-related mechanisms) are among the most
severe bugs in cloud systems and can easily cause system failures. It is notoriously difficult …

Large-scale parallel file systems (PFSs) play an essential role in high-performance
computing (HPC). However, despite their importance, their reliability is much less studied or …

We describe metastable failures---a failure pattern in distributed systems. Currently,
metastable failures manifest themselves as black swan events; they are outliers because …

A major threat to distributed software systems' reliability is vicious cycles, which are
observed when an event in the distributed software system's execution causes a system …

In this paper, we introduced the framework to empowerment resource discovery units for
supporting distributed exascale computing systems with high consistency. In addition to the …

Understanding the performance of data parallel DNN training at large-scale is crucial for
supporting efficient DNN cloud deployment as well as facilitating the design and …

Isolation Levels (IL) act as correct contracts between applications and database
management systems (DBMSs). The complex code logic and concurrent interactions among …

Distributed systems are expected to correctly recover from various faults, eg, node
crash/reboot and network disconnection/reconnection. However, faults that occur under …
