IHK/McKernel is a light-weight multi-kernel operating system designed
for high-end supercomputing. It runs Linux and McKernel, a light-weight
kernel (LWK), side-by-side inside compute nodes and aims at the
following:
- Provide scalable and consistent execution of large-scale parallel
scientific applications, but at the same time maintain the ability to
rapidly adapt to new hardware features and emerging 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
(slow-path) system calls to Linux
