Today's hardware and system software make an inadequate platform, particularly given support for synchronous programming models is deemed critical for software productivity. Novel microsecond-optimized system stacks are needed, reexamining questions around appropriate layering and abstraction, control and data plane separation, and hardware/software boundaries. Such optimized designs at the microsecond scale, and corresponding faster I/O, can in turn enable a virtuous cycle of new applications and programming models that leverage low-latency communication, dramatically increasing the effective computing capabilities of warehouse-scale computers." --=20 Dave T=C3=A4ht CEO, TekLibre, LLC http://www.teklibre.com Tel: 1-669-226-2619
