I find these type of efforts somewhat disappointing. So much OS research boils down to “We’ll handle scheduling and rudimentary peripheral multiplexing good luck on rest”. These basics are so far from a useful system that you’d have to slap linux on top and immediately lose most/all benefits of the new architecture.

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://htor.inf.ethz.ch/ross2012/slides/ross2012-akkan.pdf https://insidehpc.com/2009/10/tilera-100-core-x86-architecture/ https://insidehpc.com/2009/10/tilera-100-core-x86-architectu... https://lwn.net/Articles/549580/ https://lwn.net/Articles/549580/ https://lwn.net/Articles/816298/ https://lwn.net/Articles/816298/
