McKernel: a light-weight multi-kernel operating system
By Thom Holwerda on 2018-11-28 00:19:28

IHK/McKernel is a light-weight multi kernel operating system designed specifically for high performance computing. It runs Linux and McKernel, a lightweight kernel (LWK), side-by-side on compute nodes primarily aiming at the followings:

  • Provide scalable and consistent execution of large-scale parallel applications and at the same time rapidly adapt to exotic hardware and new programming models
  • Provide efficient memory and device management so that resource contention and data movement are minimized at the system level
  • Eliminate OS noise by isolating OS services in Linux and provide jitter free execution on the LWK
  • Support the full POSIX/Linux APIs by selectively offloading system calls to Linux
