Keeping checkpoint/restart viable for exascale systems
… techniques to ensure progress across faults like checkpoint/restart, the dominant fault tolerance mechanism for the last 25 years, are increasingly problematic at the scales of future systems due to their excessive overheads. In this work, we evaluate a number of techniques to decrease the …

A semi-blocking checkpoint protocol to minimize checkpoint overhead
… fault tolerance strategy. Double in memory/disk checkpointing is a production fault tolerance strategy in Charm++ runtime system. Each node will store one copy of its checkpoint in its own memory or disk as a local checkpoint and another copy in other node’s memory or disk as a global checkpoint. …

Advanced I/O Techniques for Efficient and Highly Available Process Crash Recovery Protocols
… has created a system-level fault-tolerant checkpoint/restart implementation for Linux Clusters. This allows processes to restart computations at the last known checkpoint in the event the system crashes. The checkpoint data creation is highly dependent on system input and output operations. …

A Personal Virtual Computer Recorder
… seen before. DejaView records visual output, checkpoints corresponding application and file system states, and captures onscreen text with contextual information to index the record. A user can then browse and search the record for any visual information that has been previously displayed on …

On Optimizing and Leveraging Distributed Shared Memory for High Performance, Resource Aggregation, and Cache-coherent Heterogeneous-ISA Processors
… this, the dissertation presents a distributed checkpoint/restart mechanism that allows a distributed VM to tolerate failures. A user interface is introduced for sending/receiving checkpoint/restart commands to a distributed VM. We implement the checkpoint/restart technique in the native KVM …

Using Rollback Avoidance to Mitigate Failures in Next-Generation Extreme-Scale Systems
… extreme-scale systems. Coordinated checkpointing is currently the most widely-used mechanism for handling failures on HPC systems. Although coordinated checkpointing remains effective on current systems, increasing the scale of today's systems to build next-generation systems will …

Scalable message-logging techniques for effective fault tolerance in HPC applications
… the state of the application and rolling back to checkpoints in case of failures. Two well-known rollback-recovery techniques are checkpoint/restart and message-logging. The former is easier to implement and has become the de facto standard to make applications fault tolerant. It has, however, a …

Runtime support for object-based message-driven parallel applications on heterogeneous clusters
… system features. For example, support for a checkpoint/restart fault tolerance mechanism has been integrated into our accelerator extensions, allowing applications making use of accelerators to make use of this fault tolerance scheme with no additional effort by the programmer.

From detection to optimization: impact of soft errors on high-performance computing applications
As high-performance computing (HPC) continues to progress, constraints on HPC system design forces the handling of errors to higher levels in the software stack. Of the types of errors facing HPC, soft errors that silently corrupt system or application state are among the most severe. The behavior …
