The evolution of supercomputers from very expensive special machines to cheaper high performing computing (HPC) has made very fast and advance systems available to an audience much vaster now than just 10 years ago. However, more computing power per installation and more installations mean more electrical power needed and more complex heat management. Evaluating the Total Cost Ownership (TCO) of a HPC solution over its lifespan is a good approach to compare different options and proceed towards the most efficient one. Density, location, size of the installation, type of cooling chosen, square footage, level of redundancy needed, complexity of the data centre and type of interconnect network are factors that contribute to low maintenance cost and less non IT related capital investments. Also, with rising costs of energy and HPC power-hungry systems, energy expenditure in the buying decision is a very important factor to be considered. Thus, HPC platforms are trying to be more cost efficient, not only for green IT but also for the economic health of the HPC data centers.
In this seminar we will review the concept of the total cost of ownership in HPC as well as the main issues and considerations to optimize acquisition costs of supercomputers during its lifetime. This seminar will be given in English.
Die Themenvergabe und die Terminabsprache erfolgt in einem Vorbesprechungstermin und über die Veranstaltungsmailingliste.
