Server Virtualization for High-Performance Computing: Potential Field of Application
The problem of web hosting is one that many site owners have had to grapple with. Do you host your site on your own computer or someone else’s? How can you share web-hosting resources without compromising efficiency?
Some people have come up with a variety of solutions. One of those solutions is cloud computing. This kind of computing refers to networked remote computers that will store, manage, and process data on behalf of users who are permitted to access the services. It is therefore possible for you to run your applications from anywhere in the world as long as you have internet connection.
In line with this kind of computing is server visualization, which refers to the use of software, to partition a physical server, in various virtual environments. This means that multiple users can use the same server for different purposes.
Applications of Server Visualization for High Performance Computation:
1. Large Memory Systems
A physical server is a hardware that has a limited amount of space. Unless the physical memory resources are changed physically, enhancing memory capabilities becomes difficult in reality. However, using virtual machines helps to overcome this obstacle. Each machine can assume a virtual memory storage capability, which increases the amount of storage areas. This is because the virtual machines act as alternate places to store data for use instead of only using the physical hardware.
2. Computer-intensive shared memory applications
Some applications need more memory storage while others need less. When each server only runs one application, lots of memory storage is wasted. However, server visualization can assign a virtual memory pool just to take care of the memory aspect of computing. Applications running within that server and other networked ones can then be clustered together to access the memory storage on a need-to basis. This overcomes the physical memory limitations while enhancing memory storage and use efficiency.
The memory pool is therefore enhanced virtually for user machines that may sometimes require high, then low memory storage sizes.
3. Cluster Interconnect
When one server is used to host an application, it will have to do everything from processing, to storage. Running virtual machines on one server on the other hand enables you to cluster applications on servers. Memory retrieval and storage can be assigned to one virtual machine while processing can be assigned to another. Connections via networks help with communication. This kind of dedicated functioning where interconnected machines and apps perform similar functions is known as cluster interconnect.
4. Simplified I/O architecture
Virtual machines help to reduce the number of computers needed to run different applications that need to be hosted. You therefore will not have to deal with many hardware components and network links. The simplification of the I/O architecture is what server visualization is all about.
5. Improved Utilization
It is important for users to make use of computing systems in the most effective and efficient manner possible. Server visualization enables this because it clusters servers based on functionality to streamline tasks. This manner of hosting also dedicates different pools for specific function. Different applications can run on one server thus utilizing all the available resources to prevent wastage.
