Y-HPC 2.0 installs 5 main components to the head node: Y-HPC GUI, Y-HPC daemon, Ganglia (as of v2.0), a set of basic node images, and a set of boot files.
Y-HPC GUI
The GUI supplies a graphical interface to the system. It allows configuration of the daemon as well as node setup and a quick view of node status.
Y-HPC daemon
The core Y-HPC component. It runs at all times on the head node and manages all communication and control between the head node and the compute nodes, as well as between the head node and a GUI if one is running.
Ganglia
Y-HPC uses Ganglia as a means of monitoring "life signs", reporting information to update the graphical interface.
Node Images
The provided node images are a minimal installation, only those packages required for a compute node.ppc: Provided with the Power architecture (ppc directory at YDL.net) ISO are 2 images: ppc64 (Apple G5) and PS3.These may be copied and modified to produce node images for various roles. As they are stored in an unpacked format, it is possible to chroot into each and customize as though they were a live system.
x86: Provided with the x86 architecture (x86 directory at YDL.net) is a single node image for x86-64.
Boot Files
The files provided in the yhpc-bootfiles-* rpms are necessary for proper network boot and startup of the compute nodes.
