Resumen de The Barrelfish multikernel: an interview with Timothy Roscoe
Increasing CPU performance with faster clock speeds and even more complex hardware for pipelining and memory access has hit the brick walls of power and bandwidth. Multicore CPUs provide the way forward but also present obstacles to using existing operating system design as they scale upswards. Barrelfish represents an experimental operating system design where early versions run faster than Linux on the same hardware, with a design that should scale well to systems with many cores and even different CPU architectures.
