December 2015 Summaries

Rescale's budget feature allows users to manage and control their simulation costs by setting spending limits at the user, company, or project level. Individual users can set personal budgets in their account settings, while company administrators can establish budgets for the entire organization or specific projects via the company's administration portal. Budgets encompass various costs, including hardware, software, data transfer, storage, and license proxy, and there is no set timeframe, meaning all accumulated costs are considered. If a budget is exceeded, new jobs are queued, and running jobs are terminated until the budget is adjusted. This feature aims to help users efficiently manage expenses during simulations, offering flexibility to adjust budgets as needed to prevent job interruptions. For more information or assistance, users are encouraged to contact Rescale directly.

The article outlines the process of creating diagrams using React, SVG, and Facebook's css-layout library to help Rescale users visualize communication between their compute nodes and on-premise license servers. SVG is favored for its integration with the DOM, but its coordinate system presents layout challenges, which are addressed by employing css-layout to apply CSS's flexbox model. The approach allows for dynamic diagram updates in response to component state changes, quick adaptation to new requirements, and localization using existing UI methods. The initial wireframing is done using HTML and css-layout's default styles, and a layout tree is constructed from this wireframe to position SVG elements accurately. Finally, the layout information is utilized within React to render the diagram, with attention to positioning details such as manual text alignment, inspired by a blog post on laying out D3 charts.
