Several European flagship projects have emerged towards European sovereignty in chip design and computing infrastructure. Among them, the EU Processor Initiative (EPI) spearheads the development of the first EU processor. To ensure the successful integration of the EU processor into the cloud computing ecosystem and strengthen even more EU data sovereignty, it is necessary to develop the software support at the same pace with the hardware development. The harmonic relationship of the developed software and hardware is of paramount importance in order to establish an EU cloud platform able to compete with the mainstream solutions which are currently delivered by US companies. AERO aims to upbring and optimize an open-source software ecosystem that encompasses a wide range of software components ranging from operating systems to compilers, runtimes, system software and auxiliary software deployment services for cloud computing. The AERO software stack combines the aforementioned software components with novel software and hardware interfaces as a means to seamlessly exploit the heterogeneity aspects of the EU processor with regards to high performance, energy efficiency, and security. The ultimate objective of AERO is to facilitate easy migration of existing cloud customers to a cloud infrastructure that harnesses the capabilities of the EU processor. To showcase early adoption and the potential business value, the developed software and hardware technologies will be piloted by use cases representative of important EU industrial domains, such as automotive and space exploration.

Vitamin-V aims to develop a complete RISC-V open-source software stack for cloud services with iso-performance to the cloud-dominant x86 counterpart and a powerful virtual execution environment for software development, validation, verification, and test that considers the relevant RISC-V ISA extensions for cloud deployment. Specifically, commercial cloud systems make use of hardware features that are currently unavailable in RISC-V virtual environments (not to mention the lack of specific RISC-V hardware). These features include the virtualization, cryptography and vectorization for which Vitamin-V will add support in three virtual environments: QEMU, gem5 and cloud-FPGA prototype platforms. Vitamin-V focuses and will provide support for EPI-based RISC-V designs for both the main CPUs and cloud-important accelerators (for memory compression). We will add the compiler (LLVM-based) and toolchain support for the ISA extensions. Moreover, novel approaches for the validation, verification, and test of software trustworthiness will be developed considering. Vitamin-V will port and evaluate several cutting-edge VMMs and container suites (i.e. VOSySmonitor, KVM, QEMU, Docker, RustVMM, Kata containers), cloud management software (i.e., OpenStack, and Kubernetes) together with their software and libraries dependencies (e.g. JVM, Python); and AI (i.e Tensorflow) and BigData applications (Apache Spark). These software suites are representative of the three cloud setups that will be demonstrated: classical (OpenStack), modern (Kubernetes), and serverless (RustVMM, Kata, Kubernetes). The cloud setups will be benchmarked against relevant AI (i.e., Google Net, ResBet, VGG19), BigData (TPC-DS), and Serverless applications (FunctionBench, ServerlessBench). Vitamin-V aims to match the software performance of its x86 equivalent while contributing to RISC-V open-source virtual environments, software validation and cloud software suites.
