Fabric Engine has highlighted the speed of usability advantages of dynamic languages, but says that they are ultimately slow compared to compiled languages unless rebuilt to provide performance — which in turn introduces additional costs.
The company's USP rests upon its claim that Fabric Engine will give the "same performance" as multi-threaded C++, yet retain the ease of use and speed of iteration of dynamic languages.
According to the company's official news stream, "On the server and in the cloud, Fabric Engine is ideal for addressing compute-bound problems that require raw execution performance. With node.js, Fabric Engine provides an asynchronous compute model that works well alongside the other services that node provides."
NOTE: High-performance applications (HPC) encompass such apps as those used in game development, animation, film production, GIS, medicine, and other industries that are greedy for performance.
Fabric Engine currently runs as a browser plug-in and is currently in beta for a Python/QT desktop framework.
