Short Message Service (SMS) has become extremely popular in many countries, and represents a multi-billion dollars market. Yet many consumers consider that the price charged by the cellular network operators is too high. In this paper, we explain that ther ...
Short Message Service (SMS) has become extremely popular in many countries, and represents a multi-billion dollars market. Yet many consumers consider that the price cellular network operators charge for it is too high. In this paper, we explain that there ...
We compare two systems for parallel programming on networks of workstations: Parallel Virtual Machine (PVM) a message passing system, and TreadMarks, a software distributed shared memory (DSM) system. We present results for eight applications that were imp ...
The message passing programs are executed with the Parallel Virtual Machine (PVM) library and the shared memory programs are executed using TreadMarks. The programs are Water and Barnes-Hut from the SPLASH benchmark suite; 3-D FFT, Integer Sort (IS) and Em ...
We present a number of experiments showing that for compute-intensive applications executing in parallel on clusters of workstations, message logging has higher failure-free overhead than coordinated checkpointing. Message logging protocols, however, resul ...
Message logging and check pointing can provide fault tolerance in distributed systems in which all process communication is through messages. This paper presents a general model for reasoning about recovery in these systems. Using this model_ we prove that ...
In a distributed system using message logging and checkpointing to provide fault tolerance, there is always a unique maximum recoverable system state, regardless of the message logging protocol used. The proof of this relies on the observation that the set ...
