Dear Colleagues,

The main topic of this issue will be on high-performance computing, rapidly evolving technologies and computing architectures, and increasing demand for extreme computation, data processing, high-performance data analysis, and artificial intelligence. High-performance computing is evolving from systems dedicated to pure computation or simulation to general purpose infrastructure also suitable for fast data processing, machine learning, data store and preservation, while the HPC centers are being upgraded with hyper-converged networks connecting them to other research or public facilities. High-performance computational techniques and algorithms are rapidly evolving and are being used and reused by research communities that historically did not rely on HPC, as well as by industry and public sector.

With this perspective, the Special Issue aims to contribute to the field presenting the most relevant advances in this area.

The following are some of the topics proposed for this Special Issue (but papers need not be limited to these):

• Design and architecture of novel CPU, GPU, FGPA, and other computational units for future high-performance systems
• Innovative architectures of HPC systems, novel approaches to scalability in computation and data processing, energy efficiency
• Algorithms for energy efficient computation at exa-scale
• Application development and porting to novel scalable architectures, high-performance toolkits, programming abstraction for different architectures
• Resource federation, integration with hyper-converged networks, federated authentication and authorization through IdP, security
• Large scale HPC application integration with fog, edge, distributed computing, clouds, virtualization and containerization
• Application use-cases, initiatives, project on exa-scale compute and data projects
• Quantum Computing technologies and applications

Manuscript Submission Information

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. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short 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 thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
