Distributed checkpointing algorithms play an important role in the majority of the fault tolerant software components existent today. Unfortunately, there is a lack of comprehensive and uniform performance testing of those algorithms. Our research focuses on the provision of a toolkit, Metapromela, that helps with the implementation and testing of distributed checkpointing algorithms. This pape...

Recently, an algorithm-based approach using diskless checkpointing has been developed to provide fault tolerance for high-performance matrix operations. With this approach, since fault tolerance is incorporated into the matrix operations, the matrix operations become resilient to any single processor failure or change with low overhead. In this paper, we present a technique called multiple chec...

In this paper, we have proposed a new checkpointing / recovery algorithm for ring network architecture. The checkpointing algorithm produces a consistent set of checkpoints in a uni-directional network with the help of few control messages and also avoids the overhead of taking temporary checkpoints unlike most other existing checkpointing algorithms. The number of interrupts to the processes i...

We consider the problem of checkpointing a distributed application efficiently in Content Centric Networks so that it can withstand transient failures. We present CCNCheck, a system which enables a sender optimized way of checkpointing distributed applications in CCN’s and provides an efficient mechanism for failure recovery in such applications. CCNCheck’s checkpointing mechanism is a fork of ...

This paper describes a non-blocking checkpointing mode in support of optimistic parallel discrete event simulation. This mode allows real concurrency in the execution of state saving and other simulation specific operations (e.g. event list update, event execution), with the aim at removing the cost of recording state information from the completion time of the parallel simulation application. ...

Checkpointing is the act of saving the state of a running program so that it may be reconstructed later in time. It is an important basic functionality in computing systems that paves the way for powerful tools in many elds of computer science. This article provides a comprehensive overview of checkpointing in uniprocessor and parallel processing systems, including deenitions, uses of checkpoin...

Smart systems in telemedicine frequently use intelligent sensor devices at large scale. Practitioners can monitor non-stop the vital parameters of hundreds of patients in real-time. The most important pillars of remote patient monitoring services are communication and data processing. Large scale data processing is done mainly using workflows. Some workflows are working in real-time, more compl...

Conclusions ~~ The limited stable storage available in mobile-computing environments can make traditional checkpointing and message logging umuitable. Since storage on a mobile liost is not considered stable, most protocols designed for these environments save the checkpoints on base stations. Previous approaches have assumed that the base station always has sufficient disk space for storing ch...
