Multiverse: Easy Conversion of Runtime Systems into OS Kernels via Automatic Hybridization
The hybrid runtime (HRT) model offers a path towards high performance and
efficiency. By integrating the OS kernel, runtime, and application, an HRT
allows the runtime developer to leverage the full feature set of the hardware
and specialize OS services to the runtime's needs. However, conforming to the
HRT model currently requires a port of the runtime to the kernel level, for
example to the Nautilus kernel framework, and this requires knowledge of kernel
internals. In response, we developed Multiverse, a system that bridges the gap
between a built-from-scratch HRT and a legacy runtime system. Multiverse allows
unmodified applications and runtimes to be brought into the HRT model without
any porting effort whatsoever by splitting the execution of the application
between the domains of a legacy OS and an HRT environment. We describe the
design and implementation of Multiverse and illustrate its capabilities using
the massive, widely-used Racket runtime system.Comment: Published in the Proceedings of the 14th International Conference on
