| Popis: | High-performance computing (HPC) is essential for scientific research, enabling complex simulations and analyses across various fields. However, the specialized knowledge required to utilize HPC effectively can be a barrier for many scientists. This work introduces a hardware-agnostic, large-scale tiled linear algebra framework in Julia designed to enhance accessibility and usability without compromising performance. By providing a flexible abstraction layer, the framework simplifies the development and testing of new algorithms across diverse computing architectures. Julia language’s multiple-dispatch and type inference facilitate the development of type-agnostic, hardware-agnostic, and multi-use frameworks by allowing composability. Utilizing a tiled approach, the implemented framework improves data locality, parallelism, and scalability, making it well-suited for modern heterogeneous environments. Its practical benefits are demonstrated through the implementation of tiled QR-based singular value decomposition (SVD), demonstrating how it streamlines the development process and accelerates scientific discovery. The developed framework is used to implement an in-GPU tiled SVD and an out-of-core GPU-accelerated SVD. Furthermore, its extensibility is demonstrated by implementing a tiled QR algorithm. This work aims to democratize HPC resources by bridging the gap between advanced computational capabilities and user accessibility, empowering a broader range of scientists to fully leverage modern computing technologies.
