Computer clusters and cluster grids have plenty of challenges. Even though the idea helps a group of smaller computers function as a more powerful computer, the very nature of networking various machines that may or may not be in the control of a single individual means that there are just more hard drives and operating systems for something to go wrong with. It can easily be said that open source technology helps improve computer clusters and grids.
This means that most of the participating computers need to have Linux components. These may be software programs, blog or web hosting sites, or the actual operating system of the computers in the cluster. Linux is meant to be accessible to anyone, so many Linux based programs will ask users for permission to gather information about the program on their machine. This is how open source is defined. By doing this, programmers can study problems and make improvements as needed. There is a level of trust needed in an open source environment, so many fail safes must also be in place. If a outage does occur, Linux can be restored without having to re-purchase the softwares or systems. Linux can also make corrections and push updates without slowing down a computer. This keeps the cluster working as efficiently as possible.
Certainly, many computers on a grid may be Windows based. That’s O.K. Linux is compatible with Windows. This keeps the cluster from having to be exclusive to one system, and therefore, makes more information available to the other computers on the grid. More companies are recognizing that Linux technology is good for cluster computing.
