The goal of the course is to outline the basic concepts about computer clusters. Firstly what exactly a cluster is and how to build a simple and clean cluster which provides a great starting point for more complex tasks. Also the handbook provides a guide for task scheduling and other important cluster management features. For the practical part most of the examples use Qlustar. Qlustar is a all-in-one cluster operating system that is easy to setup, extend and most importantly operate. A computer cluster consists of a number of computers linked together, generally through local area networks (LANs). All the connected component-computers work closely together and in many ways as a single unit. One of the big advantages of computer clusters over single computers, are that they usually improves the performance greatly, while still being cheaper than single computers of comparable speed and size. Besides that a cluster provides in general larger storage capacity, better data integrity. Nodes The term node usually describes one unit (linked computer) in a computer cluster. It represents the basic unit of a cluster. There a different types of nodes like head-nodes, compute-, cloud- or storage-nodes. Nodes in a cluster are connected through dedicated internal Ethernet networks. The figure below shows a simple setup of the components building a basic HPC Cluster.
Hardware hacking enthusiasts have talked about updating the eMac's logic board with a more modern Intel based logic board to make a Hackintosh while others have proposed using the eMac as a second monitor. Several have removed the CRT, analog boards and logic board replacing them by a single lcd display. This is described in the eMac LCD conversion personal page. Using the original CRT and analogs board has proven difficult because the IVAD board that is mounted directly to the back of the CRT needs to be initialized via its I2C interface before a VGA signal can be sent. The initialization sequence was finally recorded and then implemented in software using an arduino uno clone allowing the removal of the logic board. The pieMac is an apple eMac computer that has had the logic board removed and replaced by a raspberry pi. The pieMac was inspired by a thread on macrumors by patriciooholegu. The idea was to replace the logic board with a raspberry pi but this hack will allow the CRT to be used with just about any device that can provide a VGA signal at eMac resolutions and refresh rates. Images of how the components were arranged for this pieMac.
This is a computing architecture which includes a service-oriented language called Abacus, a virtual machine executes Abacus programs, a router program provides naming services and a web-based enviroment for managing and developing Abacus applications.
In the field of Computing learning from a live instructor-led and hand-on training courses would make a big difference as compared with watching a video learning materials. Participants must maintain focus and interact with the trainer for questions and concerns. In Qwikcourse, trainers and participants uses DaDesktop , a cloud desktop environment designed for instructors and students who wish to carry out interactive, hands-on training from distant physical locations.
For now, there are tremendous work opportunities for various IT fields. Most of the courses in Computing is a great source of IT learning with hands-on training and experience which could be a great contribution to your portfolio.
