When will it come to turn based OSes?
Isn’t that just any multithreaded OS running on a single core cpu?
I tried to read the wiki article on PikeOS, but apparently it too is a written ad seemingly from sysgo. Anyone with any knowledge and not their marketing department to key us in? I'd welcome words from people there who are not in marketing.
I had never heard of PikeOS, but the article says

> PikeOS (version 5.1.3), which is security-certified against Common Criteria at the EAL 5+ level

and

> PikeOS is also pre-certified against many industry software safety standards such as DO-178C for avionics, EN 50128 and EN 50657 for rail, ISO 26262 for automotive, EN 61508 for industrial and IEC 62304 for medical.

Which seems like a fairly objective description of what it is and what its goals are.

PikeOS is a proprietary variant in the L4 microkernel family (see Figure 1 in [1], and [2]).

Open source variants include the more well-known seL4 [3] and L4Re [4].

The L4 family is known for formal verification of significant parts of the system, and is used in safety-critical systems [5].

Google recently announced a system based on seL4 [6].
