Cluster Software and Its Interaction With the Operating System
Cluster Software and Its Interaction With the Operating System
- Outside Kernel - Works completely outside the kernel and on top of a machines existing operating system. Installation does not require modification of the kernel - similar to other software packages.
- Within Kernel - Other cluster environments use:
- Micro-based kernels with customised services. - Dynamic kernel module.
Installed instead or as a module within the existing kernel to supportthe desired environment. Necessary to support functionality, such asvirtual shared memory.
Difficult to achieve efficiently outside the kernel.
