Africa faces significant challenges in accessing advanced cyberinfrastructure due to resource constraints. Consequently, the African scientific community must explore innovative approaches, such as fostering collaboration and leveraging shared resources, to overcome financial barriers to cyberinfrastructure adoption. We outline the methodology and results of a preliminary discovery survey aimed at mapping High-Performance Computing (HPC) resources across Africa to support scientific computing research. The initiative stemmed from the recognition of the critical importance of an African HPC resource catalogue in fostering research and scientific collaboration. The survey is a result of the collective efforts of diverse stakeholders to promote scientific advancement throughout the continent by generating a preliminary overview of available computational resources in Africa. The survey gathered a total of 51 completed submissions from 23 African countries, establishing a solid foundation for further exploration of existing HPC resources across Africa.
