Today's largest High Performance Computing (HPC) systems exceed one Petaflops (10^ 15)
floating point operations per second) and exascale systems are projected within seven …

Authentication based on passwords is used largely in applications for computer security and
privacy. However, human actions such as choosing bad passwords and inputting passwords …

For full checkpoint on a large-scale HPC system, huge memory contexts must potentially be
transferred through the network and saved in a reliable storage. As such, the time taken to …

Fault‐tolerance is an essential part of a stream processing system that guarantees data
analysis could continue even after failures. State‐of‐the‐art distributed stream processing …

Non-volatile devices, such as SSDs, will be an integral part of the deepening storage
hierarchy on large-scale HPC systems. These devices can be on the compute nodes as part …

Checkpoint/restart has been widely used to cope with fail-stop errors. The checkpointing
frequency is most often optimized by assuming an exponential failure distribution. However …

Hardware failures and faults often result in application crash in HPC. The emergence of non-
volatile memory (NVM) provides a solution to address this problem. Leveraging the …

As the scale of High-Performance Computing (HPC) clusters continues to grow, their
increasing failure rates and energy consumption levels are emerging as serious design …

Efficient use of high-performance computing (HPC) installations critically relies on effective
methods for fault tolerance. The most commonly used method is checkpoint/restart, where …

Checkpoint-based fault tolerant method has been widely used to enhance the reliability of
Distributed Stream Processing Engines (DSPEs), but a checkpointing process usually …
