| Abstract: | This paper presents a toolkit for supporting the execution of coarse-grain, parallel (distributed) applications under the MOSIX multicomputer operating system. These tools use standard UNIX System V process control and message-passing facilities, as well as the dynamic process migration mechanisms of MOSIX. The MPE tools can be used to modify sequential applications that were originally written for execution in a uniprocessor environment, to run efficiently in a distributed environment, consisting of several loosely coupled independent computers that communicate by messages. After presenting the MPE tools, the paper gives examples of several sequential algorithms that have been modified for execution in such a distributed multicomputer, as well as the resulting execution speed-ups that were obtained. |
