A Casual History of Beowulf Clusters: A Geek’s Dream Come True
Once upon a time in the far-off world of the 1990s, a group of computer geeks, who were passionate about high-performance computing (HPC) and parallel processing, were looking for a way to build powerful computing systems without breaking the bank. Enter Beowulf clusters, the superhero of the computing world.
The Origin Story
The Beowulf cluster, named after the epic Old English poem “Beowulf,” had a humble beginning. It all started in 1994 when a couple of NASA researchers, Thomas Sterling and Donald Becker, were trying to find a cost-effective way to solve complex computational problems. They had a eureka moment and figured out how to use off-the-shelf components and free, open-source software to create a powerful and affordable HPC system.
The Dynamic Duo’s Creation
Sterling and Becker’s creation, the Beowulf cluster, was a network of commodity computers that worked together in tandem to perform a single task. The genius of this design was its ability to tap into the power of multiple computers simultaneously, creating a single, supercharged computing beast. And the best part? It was way more affordable than the traditional supercomputers of the day.
A Wild Success
The Beowulf cluster quickly gained popularity among researchers and institutions worldwide. Universities, government labs, and even businesses jumped on the bandwagon, building their own Beowulf clusters to solve complex computational problems in fields like physics, climate modeling, and data analysis. And as the hardware and software components evolved, Beowulf clusters became even more powerful and efficient.
Popular Implementations
Over the years, several popular implementations of Beowulf clusters emerged, each with their own unique features and advantages. Some of the most notable ones include:
-
OSCAR (Open Source Cluster Application Resources): OSCAR was a popular, user-friendly Beowulf cluster management system. It provided a comprehensive suite of open-source tools and software that made it easy for users to deploy, manage, and maintain their clusters.
-
Rocks Cluster Distribution: Rocks was another popular Beowulf cluster management system that emphasized simplicity and ease of use. It was designed to automate the process of building, managing, and scaling clusters, making it an attractive option for users who wanted a low-maintenance solution.
-
Scyld ClusterWare: Scyld ClusterWare was a commercial Linux-based Beowulf cluster management software that provided a more turnkey solution. It offered advanced features like single-system-image functionality, which made it easier to manage large clusters by treating them as a single, unified system.
Problems Suited for Early Beowulf Clusters
Beowulf clusters, with their ability to harness the power of multiple computers working in parallel, were particularly well-suited for solving a wide range of computationally intensive problems. Some of the most common applications included:
-
Physics and Astronomy: Beowulf clusters were widely used in the field of physics to simulate complex phenomena, such as particle collisions in high-energy physics, and in astronomy to model the formation and evolution of galaxies.
-
Climate Modeling: Researchers in climate science relied on Beowulf clusters to create detailed simulations of Earth’s climate, helping to improve our understanding of factors that contribute to climate change and predict future trends.
-
Computational Fluid Dynamics (CFD): Beowulf clusters were an excellent tool for CFD simulations, a crucial method used in many engineering applications, such as aerospace and automotive design. These simulations required vast amounts of computational power to model the behavior of fluids, making Beowulf clusters an ideal solution.
-
Genomics and Bioinformatics: Beowulf clusters were widely adopted in the field of genomics and bioinformatics, enabling

RS-232 BASIC
Throughout the years, the RS-232 has proven to be incredibly adaptable. It became a popular interface for connecting computers and peripherals like mice, modems, and printers. One reason for its popularity was its simplicity - it’s an asynchronous, point-to-point protocol that doesn’t need a clock signal, making it relatively easy to implement.
But, as with all good things, the RS-232 had its limitations. Its maximum data rate of 20 kbps and limited range of 50 feet made it ill-suited for high-speed data transfers or long-distance communication. As a result, newer standards like RS-422, RS-485, and USB began to take over the market.
However, despite being overshadowed by newer and faster communication protocols, the RS-232 has maintained a loyal fan base. In fact, it still has niche applications in the world of automation and industrial equipment, where its simplicity and robustness make it a reliable choice.
So, there you have it - the casual history of the RS-232. It may not be the latest and greatest, but this resilient and adaptable standard has played a crucial role in the evolution of data communication. And for that, it deserves our respect and appreciation.

Problems to solve
At the moment I’m pretty frustrated with this project mostly because I messed a part up.
Primes
** Important note ** We’re going for understanding and first princples here. I’ve chosen readability and simplicity over speed.
Seriosuly, don’t get all twisted out of shape here. No one wants to hear how you’d make this faster because you’re the god of 40 year old BASIC.
