W artykule przedstawiono istotne problemy w wykorzystaniu współczesnych superkomputerów i wieloprocesorowych klastrów do rozwiązywania złożonych problemów w obliczeniach naukowo-technicznych, przemysłowych i komercyjnych. Do istotnych problemów należy zaliczyć: parametry techniczne i funkcjonalność oprogramowania, rozwiązania podnoszące niezawodność oferowanych usług i ich bezpieczeństwo, ciągłość pracy, wybór sprzętu i koszt obliczeń.

We describe crucial problems ralated to application of modern supercomputers and multiprocessor clusters to solving complex problems in scientific, industrial and comercial computations. These problems include: technical parameters, functionality of software, security and quality of services, continuity of operation, choice of hardware and computational costs.

An introduction to high performance computing: technology, tools and applications

Traditionally high performance was applied to very computationally demanding problems in science and engineering. They were known as the Grand Challenge Problems that required supercomputers equipped with very large computer memories and capable of high rates of computation measured by Megaflops (million floating point operations per second). In the last two decades the world of business and industry has recognized the enormous potential of large distributed computer systems for their business enterprise applications. Today most of the existing high performance computers are employed in the enterprise environments. A typical system has three layers of servers: user interface, applications and database. These client/server architectures are the work horse of large enterprise information processing. This introductory paper describes both areas of high performance computing applications that differ in the nature of workload, performance objectives, design methodology and scientific focus.
