Linux clusters have become the paradigm of choice for the execution of applications of science, engineering and commerce in a large scale. This is because computing using cluster technology is cheaper, has high performance, availability of many components - compenents own hardware and software that we can get for free that can be used to develop applications of the cluster. This book discussing about technology, Linux clusters, the architecture of the system, software that is used to develop applications (parallel program). The aim of this study is to know the performance of 8 processor computers using cluster with Debian linux. To test this Final project will be sorting the applications in use by many of the numbers in the thousands of numbers. To monitor the performance of computer processor at cluster while executing parallel programs The results of the monitoring processor performance will be displayed in real time in graphical for
