CLUSTER COMPUTING INTRODUCTION

              In computers, clustering is the use of multiple computers, typically PCs or UNIX workstations, multiple storage devices, and redundant interconnections, to form what appears to users as a single highly available system. Cluster computing can be used for load balancing as well as for high availability. Advocates of clustering suggest that the approach can help an enterprise achieve 99.999 availability in some cases. One of the main ideas of cluster computing is that, to the outside world, the cluster appears to be a single system.

             A common use of cluster computing is to load balance traffic on high-traffic Web sites. A Web page request is sent to a "manager" server, which then determines which of several identical or very similar Web servers to forward the request to for handling. Having a Web farm (as such a configuration is sometimes called) allows traffic to be handled more quickly.
Clustering has been available since the 1980s when it was used in DEC's VMS systems. IBM's Sysplex is a cluster approach for a mainframe system. Microsoft, Sun Microsystems, and other leading hardware and software companies offer clustering packages that are said to offer scalability as well as availability. As traffic or availability assurance increases, all or some parts of the cluster can be increased in size or number.
             Cluster computing can also be used as a relatively low-cost form of parallel processing for scientific and other applications that lend themselves to parallel operations. An early and well-known example was the Beowulf project in which a number of off-the-shelf PCs were used to form a cluster for scientific applications.

MAKE WINDOWS 8 EASIEAR AND QUICKER TO USE

Windows 8 can be frustrating because nothing seems to be where it used to be. Here are three tricks that help you find things. They will make ordinary tasks much easier to carry out.

1. Quick and easy way to access all the settings in Windows 8

One of the annoyances of Windows 8 is trying to find all the various system settings. Here is a way to make them readily available in one big list.

1. Go to the Desktop
2. Right-click an empty spot on the Desktop
3. Choose “New-Folder”
4. Give the folder this name:
   All Settings .{ED7BA470-8E54-465E-825C-99712043E01C} 
5. Open the folder to see a complete list of settings

(This works in Windows 7 also where it is sometimes called “God Mode”.)

2. How to shut Down Windows 8 quickly

Shutting down Windows 8 the usual way involves multiple steps. You have to open the Charms bar, click "Settings", then "Power", and finally "Shut down". Here is how to create a desktop shortcut that will reduce these four steps to just one.

1. Go to the Desktop
2. Right-click an empty spot on the Desktop
3. Choose “New-Shortcut”
4. Go to the line labelled “Type the location of the item…”
5. Enter:  shutdown.exe -s -t 0 (The last character is "zero".)
6. Click “Next”
7. Type a name like Shutdown
8. Click “Finish”

Once the shortcut is created, you can pin it to the Taskbar:

1. Right-click the shortcut
2. Click “Pin to Taskbar”

You can also place the shortcut on the Metro (Modern) interface:

1. Right-click the shortcut
2. Click “Pin to Start”

Start in this case refers to the Start Screen and places a copy of the shortcut along with the tiles on the Metro interface.

3. How to put commonly used folders and functions on the Desktop

The default desktop in Windows 8 is pretty bare. If you would like ready access on the desktop to some commonly used features, here is how:

1. Go to the Desktop
2. Right-click an empty spot on the Desktop
3. Select “Personalize”
4. On the upper left of the dialog box, click “Change desktop icons”(shown in graphic on right)
5. In the dialog that opens (shown below) put a check by the icons you want on the desktop. Control Panel is one I like to have
6. Click “OK” and close the Personalization window

And there you have it - three ways to make using Windows 8 a little easier

DISABLE WINDOWS 8 AUTOMATIC MAINTENANCE

Microsoft reiterated that Windows 8 has been built upon the solid foundations of its predecessor. Well, there is no denying this fact, because apart from looking stunning, Windows 8 includes several robust features under the hood that make it fast, stable and snappy, just like the previous version. One of the refreshing additions to this feature-set is automatic system maintenance (also called Regular Maintenance), which checks for software updates, system diagnostics and security scanning tasks, on regular basis. This option ensures that maintenance tasks are performed at a specified time, provided you’re not around and the system is idle. In what follows, we will guide you through the process of changing time settings to run the daily maintenance task, whether to allow the schedule maintenance to wake your machine, as well as disable this feature if you don’t need it.

Change Scheduled Maintenance Time

To change time settings for automatic system maintenance, click the Action Center icon in the System Tray followed by ‘Open Action Center’. Alternatively, you can access the Action Center from the Control Panel.

 

In the Action Center window, click the arrow beside Maintenance to expand its settings, and then click ‘Change maintenance settings’ under the Automatic Maintenance section, as demonstrated in the screenshot below.

Here, you can choose the maintenance time according to your liking. Windows 8 sets this time to 3:00 AM by default, but you can change it to any other time. Furthermore, you can enable/disable the optional ‘Allow scheduled maintenance to wake up my computer at the scheduled time’. When done, click OK to apply the changes. If prompted by the UAC, simply click the Yes button.

Disable Automatic Maintenance

Apart from changing time parameters, you can also disable the Automatic Maintenance option altogether. This can done from within the Windows Task Scheduler utility. To do so, press Win+W to call the Search Charm and type “task scheduler” or “schedule tasks”. Selecting Schedule tasks from the left will launch the Task Scheduler window.

Task Scheduler is Window’s native utility that allows various system or user applications to be launched or triggered automatically at a user defined time. It houses three navigation panes. The left pane lets you select the task, the center pane contains information regarding the selected task, while the right pane contains further pertaining actions.

From  the left pane, navigate to:

Task Scheduler Library > Microsoft > Windows > TaskScheduler

Right click ‘Regular Maintenance’ from the center pane and select Disable from its context menu.

That’s it! You have successfully disabled Regular Maintenance.
