Computing has changed in recent years, with the demand for high-performance computing (HPC) rising every single day. Many advancements were made, with most notable breakthroughs in the form of artificial intelligence and supercomputing. Meanwhile, Linux has created an ecosystem that is super adept at supercomputing efficiency, offering a robust and flexible platform for engineers. Without a doubt, the capabilities of the Linux system have changed the landscape of techdev with its innovations. Why Linux is the Operating System of Choice for Supercomputers There are many benefits of Linux and there is more than one reason why Linux is the first choice for many engineers and researchers. The platform it offers is highly scalable and flexible, including tools to optimize for HPC tasks, such as automatic vectorization in GCC (GNU Compiler Collection), OpenMP (Open Multi-Processing), and OpenMPI (Open Message Passing Interface), all of which aid in the optimization of HPC applications. Another benefit of Linux is that, regardless of programming language, Linux has a large set of capabilities to support them, which makes it much easier for developers to utilize the platform and implement solutions that are tailored to the applications as needed. The open-source nature of Linux encourages both growth and innovation by relying on the wisdom of the crowd - having hundreds of thousands of users all over the world contributing to its advancement. It also fosters a sense of community, and true enough, there is a vibrant community of developers that support one another’s research, collaborating in unison for the betterment of tech. In today’s landscape, 90% of the world’s most sophisticated supercomputers are powered by Linux. Moreover, for more than 20 years, Linux systems have filled more than half of the spots in the top 500 list of the most powerful machines in the world. Even back in 2018, all of them have become Linux powered, and, at that time, two new systems entering the list were IBM machines based on the POWER9 family of processors, with newly implemented supercomputer features designed by Gabriel Gomes, in the form of “compiler-toolchain software for high-precision, high-performance, floating-point arithmetic integrated into the core math library”, as he recalls. Now almost a decade later, Linux is still at the forefront, pushing the envelope for supercomputing and setting the standard for open-source platforms. Current HPC trends and cyber security Technology is constantly being upgraded. Developers and programmers never rest in their quest to find better solutions. With the integration of AI and machine learning, more doors have opened to researchers, and it is really up to the imagination how they apply the technology to create new and innovative solutions. In current trends, libraries like TensorFlow and PyTorch, which are optimized for Linux environments, are taking over because they are also open-sourced and rely on developers who work on underlying optimizations that enhance the performance of these machine learning algorithms. Optimization is not the only concern for HPC, though. The large amounts of data it consumes, as well as the A.I. models produced by the processing of this data are highly valuable assets and thus an increasingly common target for cybercrime and cyber security. Linux is again well positioned in this field, since having so many users using the platform means that vulnerabilities are quickly picked up and dealt with. Independently of the technique used - be it code review, static or dynamic analysis, or even automated A.I. solutions - detecting vulnerable paths before threats have a chance to manifest themselves is the goal. “A proactive approach is always better, as the saying goes, prevention is better than cure”, explains Gomes, who has been working with tech since graduating from University of Campinas and has since worked with IT hotshots like IBM and Linux distributor, SUSE. According to him, “It is important to continue fortifying the security of supercomputing systems for obvious reasons, particularly for maintaining uptime and preventing data breaches.” In this scenario, live patching is a new and valuable feature for supercomputing as it doesn’t interfere with uptime. During his time at SUSE, Gomes led the development of libpulp, a framework that allows the live patching of user-space processes, which can be used to safely apply changes to long-running computer programs. Since HPC requires performance, changes can also be reverted if their cost is deemed too high. This feature enhances the efficiency of patch management in production systems, and can be installed on any Linux distribution, explains Gomes, who is a Debian Developer in the Debian project. The Future of High-Performance Computing There is a growing reliance on supercomputing for sensitive research, which means that the performance and security of these systems will be the highest priority for future developments. The industry will continue to rely heavily on performance and security researchers that are able to focus on operating systems, compilers, libraries and patching mechanisms development for HPC. There will be increased collaboration across HPC domains, bringing together A.I., machine learning, and big data analytics. This also means that resource management will play a crucial role, as supercomputing consumes more resources than traditional computers. The development of sophisticated scheduling algorithms and workload management tools within the Linux ecosystem will further enhance resource availability and enable systems to hit peak performances. A driving force in the realm of high-performance computing, the Linux ecosystem will continue to excel and provide the technology needed to achieve greater efficiencies and capabilities, pushing forward the boundaries of what is possible in the future of computing.
