Weather and climate models, or Earth System Models (ESMs), are integral to understanding and predicting complex environmental phenomena. However, these models are often intricate and highly dependent on specific software libraries, making their installation and deployment on high-performance computing (HPC) systems both time-consuming and error-prone. The problem is exacerbated by the diversity of HPC architectures across European supercomputing centers, further complicating the deployment of ESM applications. Deliverable D1.4 focuses on developing a common software stack for Earth System Models (ESMs), leveraging automated building tools to simplify deployment across diverse high-performance computing (HPC) systems. A software list of 90 tools was compiled, and their availability was verified at multiple European HPC sites, including JSC, CSC, and BSC. Additionally, the benchmark suite HPCW developed by ESiWACE was tested at JSC, ensuring software compatibility and performance across different configurations. HPCW was also tested within the European Environment for Scientific Software Installations (EESSI), an open-source software ecosystem that provides a standardized framework for HPC deployments. The deliverable improves the efficiency and scalability of ESM deployment, enhances interoperability across European HPC centers, and contributes to the European Environment for Scientific Software Installations (EESSI) community. This work helps streamline the deployment process for ESM applications, facilitating easier installation and maintenance across various supercomputing infrastructures.
