The goal of the SMART4ALL EU funded project is to build capacity amongst European stakeholders via the development of self-sustained, cross-border experiments that transfer knowledge and technology between academia and industry. It targets Customized Low Energy Computing (CLEC) in the Cyber-Physical (CPS) and the Internet of Things (IoT) domains. The vision of the project will be mainly realized through funded (via open calls) Pathfinder Application Experiments (PAEs) that will enable the transformation of academic knowledge into products.It is important to mention that SMART4ALL sets forward the concept of marketplace which is offered as a service (Marketplace-as-a-Servtce or MaaS) that acts as one-stopsmart-stop by offering tools, HPC services, and platforms to the PAE grantees. The purpose of this paper is to present the SMART4ALL High-Performance Computing (HPC) infrastructure and services realized according to the Hardware-as-a-Service paradigm. The SMART4A11 HPC infrastructure includes CPU, Memory, GPU, storage as well as FPGA resources connected with high-speed links.
