March 2016 Summaries

Many mature MVC applications encounter issues with overly complex models, often referred to as "God Objects," which arise when initial broad concepts from product discussions are directly translated into database models and continually expanded with new business requirements. This process can lead to bloated models that encompass excessive application logic, making maintenance and feature development cumbersome. The crux of the problem lies in the translation of informal "folk object models"—the intuitive and loosely defined concepts used in human discussions—into formalized code, which can obscure hidden assumptions and edge cases. These broad models, while useful in framing product features, are often too expansive to function effectively as singular classes, necessitating a more granular approach where distinct logic is compartmentalized into separate classes. By breaking down these large models into smaller, focused components, software engineers can create more efficient and maintainable codebases that better serve the domain's specific needs.

Rescale provides a suite of software with flexible on-demand licensing aimed at optimizing computational simulations by allowing users to pay based on usage. The software is designed to encourage running simulations on more cores for faster results, with pricing models that include proportional, flat rate, capped, and discounted categories. The blog post examines how different pricing models, along with the scalability of the software, influence the overall cost-effectiveness of running simulations on multiple cores. It highlights the importance of understanding both hardware and software pricing to minimize total costs, which are calculated as the product of hourly prices and simulation duration. The discussion includes an exploration of the relationship between compute and communication times in distributed simulations, emphasizing that larger models tend to scale better due to reduced relative communication overhead. By presenting equations and assumptions, the post aims to guide users in optimizing their simulations' cost efficiency, ultimately suggesting that a good scaling software combined with a flat rate or capped pricing model often proves more economical. Rescale's support team is available to assist in estimating the optimal number of cores for specific simulations, reinforcing the idea that minor deviations in core numbers generally do not significantly affect cost savings.

Manor Racing has partnered with San Francisco-based Rescale to enhance its performance in the 2016 FIA Formula 1 World Championship by utilizing Rescale's cloud high-performance computing (HPC) platform. This collaboration allows Manor Racing to conduct real-time trackside simulations using a web-based application, significantly advancing their simulation capabilities without the need for a substantial physical footprint. The use of Rescale's technology enables engineers to execute extensive simulations and strategies instantly from a laptop, providing a competitive edge by optimizing race strategy and performance through real-time data analysis. Rescale's CEO, Joris Poort, emphasizes the transformative potential of their platform, which negates the need for massive upfront capital investment in physical computing infrastructure. This strategic partnership aligns with Manor Racing's goals of climbing the grid rankings and staying at the forefront of innovation, propelled by Rescale's cutting-edge simulation software and HPC solutions.

Rescale has announced the integration of AVL EXCITE™ into its cloud-based simulation platform, enhancing its collaboration with AVL, a leader in powertrain system development and testing. AVL EXCITE™ is a dynamic analysis solution used to assess the dynamics, strength, vibration, and acoustics of various powertrain components. Through Rescale's platform, users can utilize their existing AVL EXCITE™ licenses to run simulations via on-demand high-performance computing (HPC) across more than 30 global data centers, facilitating worldwide collaboration. This integration allows for parallel simulations and interfaces with third-party CAE software, thereby speeding up the simulation process. The collaboration aims to provide AVL users with flexible, seamless access to powerful simulation capabilities, supported by Rescale's scalable hardware and cloud computing environment.
