Keynotes about HPC -: 

Keynotes about HPC - You don’t need a 7digit-billion dollar amount to build a HPC unlike SPC. HPC runs on your desktop hardware and simple web servers. HPC is open to everyone thanks to the low cost hardware unlike the SPC which was meant for the rich guys. Built from standard off-the-shelf servers and high speed interconnects, a typical HPC system can deliver industry-leading, cost-effective performance.

Need for HPC clusters [1] -: 

Need for HPC clusters [1] - Super computers were expensive to design, fabricate and manufacture. No longer feasible to design SPC specific processors (to earn a profit you need sell a processor at millions of $ ) In addition, for certain problems it was found that by breaking a problem up into smaller sub problems, collections of commodity processors could achieve performance levels that could rival those of their supercomputing kin.

Need for HPC clusters [2] -: 

Need for HPC clusters [2] - - Indeed, as commodity processors from companies like AMD improved, collections (or clusters) of servers (each server in a cluster is commonly referred to as a node) began to outpace even the fastest supercomputers. The move to commodity hardware had begun. - Another enabler of the commodity cluster was the Internet. The Internet helped in two ways. First, it ignited the demand for Web servers whose compact data center design could offer a low-cost building block for commodity HPC clusters. And second, it opened up an avenue for international collaboration, helping solve many of the early HPC issues.

Advantages -: 

Advantages - Low cost implementation Highly scalable Distributed computing Reduced hardware failure risks Minimal wastage of computing power Any time plug and play clustering Saves you billions of dollars /super_computer

Disadvantages -: 

Disadvantages - Relatively new architecture, so lesser support from enterprises but great support from the developers, AMD and Intel. Lack of proper documentation from companies due to proprietary reasons. Will take another 2-3 years to be on par with the cloud computing.

Conclusion -: 

Conclusion - The power to model and manipulate our world in silicon has enabled vast changes in how we conduct science, business, and even our everyday lives. From the next scientific breakthrough to new and better products to a greener world, High Performance Computing (HPC) is playing a central role in all these efforts. In simple terms, HPC enables us to first model then manipulate those things that are important to us. HPC changes everything. It is too important to ignore or push aside. Indeed, HPC has moved from a selective and expensive endeavor to a cost-effective technology within reach of virtually every budget.
