Concurrent Computing Concepts
- Castle DesignStudy
Sooner as we realize, even embedded systems will have piles & heaps of cores, as I described in
“Keep those cores busy!”. Castle should make it easy to write code for all of them: not to keep them busy, but to maximize
speed up [useCase: In Castle is easy to use th... (U_ManyCore)]. I also showed that threads do not scale well for CPU-bound (embedded)
systems. Last, I introduced some (more) concurrency abstractions. Some are great, but they often do not fit
nicely in existing languages.
Still, as Castle is a new language, we have the opportunity to select such a concept and incorporate it into the language.
In this blog, we explore a bit of theory. I will focus on semantics and the possibilities to implement them efficiently. The exact syntax will come later.
Keep those cores busy!
I always claim that most computers will have 1024 or more cores before my retirement. And that most embedded systems will have even more, a decade later. However, it’s not easy to write technical software for those “massive-parallel embedded computers”, not with the current languages – simple because a developer has to put in too many details. Accordingly, the “best, ever” programming language should facilitate and support “natural concurrency”.
In Castle, you can easily write code that can run efficiently on thousands of cores.
