NAME
kerrighed - a Linux based Single System Image.SYNOPSIS
- Kerrighed
DESCRIPTION
- Kerrighed is a Single System Image operating system for clusters. Kerrighed offers the view of a unique SMP machine on top of a cluster of standard PCs. Kerrighed main features are :
Configurable Global Process Scheduler:
- Processes and threads are automatically scheduled over the cluster nodes to balance the CPU load using the Kerrighed default scheduling algorithm. However, Kerrighed offers a toolkit to easily write personal schedulers hot-loadable through kernel modules.
Distributed Shared Memory:
- Threads and System V memory segments can operate through the whole cluster, just like on a SMP machine.
High Performance Stream Migration Mechanism:
- Processes using streams (socket, pipe, fifo, char device, etc) can be migrated with no penalty on communications performance.
Distributed File System:
- A unique file name space is seen over the whole cluster. All nodes disk are merged in an unique global virtual disk.
Process Check-pointing:
- Processes can be check-pointed and restarted on any cluster node.
Full System V Interface:
- Full Posix Thread Interface.
Kerrighed is implemented as an extension to Linux operating system (a set of Linux modules and a small patch to the kernel). Kerrighed is independent of the cluster interconnection network.
