Power consumption has a direct impact on the operation and maintenance costs of High Performance Computing (HPC) centers. As we target the Exaflop barrier, the energy consumption impairs the deployment of new facilities and makes the HPC center economically unfeasible. This high consumption of power comes from the ever growing number of transistors on the processors and the steep increase in the number of them in clusters, the traditional way to obtain more and more performance. In addition, the cooling systems and other infrastructure elements required to maintain the system under a temperature threshold do nothing but increase to economical and ecological problem. Therefore, since energy consumption is nowadays a major concern in HPC, solutions to this problem stand as a crucial challenge. Much research should still be done in both hardware and software energy-aware tools to reduce power requirements. This is the challenge the HPC community will face for the upcoming years.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Computers is an international peer-reviewed Open Access quarterly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. For the first couple of issues the Article Processing Charge (APC) will be waived for well-prepared manuscripts. English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.
