The kernel provides the glue that makes all components in Blue Gene/Q system work together. This chapter provides an overview of the functionality that is implemented as part of the Compute Node Kernel (CNK) and the I/O node kernel, which includes information about the following topics:
2.1 Compute Node Kernel
The CNK is a flexible, lightweight kernel for Blue Gene/Q compute nodes that can support diagnostic modes and user applications. It provides an operating system that ...
