It's a research project. It has been influential enough. Researchers have also made hardware prototypes that pushed this message-passing-cores design ever further.

In the non-academic world, HPC and realtime people have reimplemented some of these ideas into Linux, making it so that a core can be fully dedicated to an application, not receiving interrupts ("tickless"), not handling any kernel tasks, etc. For example, https://htor.inf.ethz.ch/ross2012/slides/ross2012-akkan.pdf https://insidehpc.com/2009/10/tilera-100-core-x86-architectu... https://lwn.net/Articles/549580/ https://lwn.net/Articles/816298/
