The Middleware for Embedded Adaptive Dependability (MEAD) infrastructure enhances large-scale distributed real-time embedded middleware applications with novel capabilities, including (i) transparent, yet tunable, fault tolerance in real time, (ii) proactive dependability, (iii) resource-aware system adaptation to crash, communication, partitioning and timing faults with (iv) scalable and fast ...

In this paper we propose a dynamically reconfigurable failure recovery scheme developed for Network-on-Chip (NoC) based systems. The recovery scheme is based on a checkpointing and rollback protocol and permits enhancing the system fault tolerance capabilities by exploiting information on traffic load and failure rate. The increased performance of the fault tolerance mechanism is achieved by si...

⎯ Checkpointing schemes facilitate fault recovery in distributed systems. The two-level fault recovery scheme of distributed system inherits the merits of both disk-based and diskless checkpointing schemes. The present work extends James S Plank’s Diskless checkpointing scheme (N+1 Parity) by introducing ‘Timeout’ to checkpoint programs with high locality of reference. This mechanism enables ap...

In this paper, we focus on automated techniques to enhance the fault-tolerance of a nonmasking fault-tolerant program to masking. A masking program continually satisfies its specification even if faults occur. By contrast, a nonmasking program merely guarantees that after faults stop occurring, the program recovers to states from where it continually satisfies its specification. Until the recov...

Future high-performance computing systems may face frequent failures with their rapid increase in scale and complexity. Resilience to faults has become a major challenge for large-scale applications running on supercomputers, which demands fault tolerance support for prevalent MPI applications. Among failure scenarios, process failures are one of the most severe issues as they usually lead to t...

Julep is an object-oriented testbed designed for analysis and comparison of temporal diversity fault tolerance mechanisms. It is written in Java, and runs as a layer underneath a distributed application. Julep can run on any standard COTS platform with a JVM, in homogeneous or heterogeneous environments. Julep is designed to quickly and easily incorporate new process recovery mechanisms, allowi...

A central problem in the design of fault-tolerant realtime systems is that desirable fault-tolerance properties are usually realized by mechanisms that counteract realtime guarantees. A prominent example is the All-orNothing property (also known as failure atomicity) known from transactions. This property normally is realized by the means of isolation and roll-back recovery. However, isolation ...

Many new characteristics are introduced in the mobile computing system, such as mobility, disconnections, finite power source, vulnerable to physical damage, lack of stable storage. Since the related log-based rollback recovery fault tolerant schemes may still lead to dramatic performance loss in failure-free or inconsistent recovery caused by the fault, a hybrid log-based fault tolerant scheme...
