An error-detecting approach for fault tolerance parallel recomputing with parallel digital terrain analysis

Fault Tolerance Lessons Applied to Parallel Computing

This paper describes an approach to fault-tolerant parallel computing which is based on the experiences with the most successful fault-tolerant software – the transaction processing systems. The algorithms presented here have less runtime overhead and faster recovery than most preceding approaches. In the Pact parallel programming environment fault tolerance is provided fully user transparent i...

An Optimized Approach of Fault Distribution for Debugging in Parallel

Software Debugging is the most time consuming and costly process in the software development process. Many techniques have been proposed to isolate different faults in a program thereby creating separate sets of failing program statements. Debugging in parallel is a technique which proposes distribution of a single faulty program segment into many fault focused program slices to be debugged sim...

Parallel Fault Simulation of Digital Circuits

A new approach to parallel fault simulation for sequential circuits based on Binary Decision Diagrams (BDD) is proposed. The efficiency of BDDs for simulation is well known. However, traditional BDDs are not well-suited for fault simulation. Furthermore, up to now, they have not been used for parallel simulation. In the paper, a new class of BDDs is presented, called Structurally Synthesized BD...

Fault Tolerance of Parallel Manipulators with Passive Joints

A systematic analysis of the mobility of closed chain manipulators with passive joints is given. The main observation presented in this paper is that the mobility of the manipulator, considering the passive joints only, should always be zero. Further, for the manipulator to be fault tolerant, the mobility should remain zero when actuator failure occurs for an arbitrary joint. We present a simpl...
