CNK operating system

The IBM Blue Gene compute hierarchy. A CNK instance runs on each of the compute nodes.

Compute Node Kernel (CNK) is the node level operating system for the IBM Blue Gene series of supercomputers.[1][2]

Operating system

The compute nodes of the IBM Blue Gene family of supercomputers run CNK, a lightweight kernel that runs on each node and supports one application running for one user on that node. To maximize operating efficiency, the design of CNK was kept simple and minimal. It was implemented in about 5,000 lines of C++ code.[1] Physical memory is statically mapped and the CNK neither needs nor provides scheduling or context switching, given that at each point it runs one application for one user.[1] By not allowing virtual memory or multi-tasking, the design of CNK aimed to devote as many cycles as possible to application processing.[2]

CNK delegates file input/output (I/O) to dedicated I/O nodes which run the INK (I/O Node Kernel) operating system, based on a modified Linux kernel.[2]

One-way speed of light

Concept in relativity theory When using the term the speed of light it is sometimes necessary to make the distinction between its one-way speed and its two-way speed. The one-way speed of light, from a source to a detector, cannot be measured independently of a convention as to how to synchronize the clocks at the source and the detector. What can however be experimentally measured is the round-trip speed (or two-way speed of light) from the source to a mirror (or other method of reflection) ...
