- CNK_operating_system abstract "CNK (for Compute Node Kernel) is the node level operating system for the IBM Blue Gene supercomputer. the compute nodes of the Blue Gene family of supercomputers run CNK (for Compute Node Kernel), a lightweight kernel that runs on each node and supports a single application running for a single user on that node. For the sake of efficient operation, the design of CNK was kept simple and minimal, and it was implemented in about 5,000 lines of C++ code. Physical memory is statically mapped and the CNK neither needs nor provides scheduling or context switching, given that at each point it runs a single application for a single user. By not allowing virtual memory or multi-tasking, the design of CNK aimed to devote as many cycles as possible to application processing. CNK does not even implement file I/O on the compute node, but delegates that to dedicated I/O nodes. the I/O nodes of the Blue Gene family of supercomputers run INK (for I/O Node Kernel). INK is based on a modified Linux kernel.↑ 1.0 1.1 1.2 ↑ 2.0 2.1 2.2 2.3".
