Default Partitioning

Master Node

The default Scyld partition table allocates 4 partitions:

• /boot partition

• /home partition

• / partition

• Swap partition = 2 times physical memory

Compute Nodes

The default partition table allocates three partitions for each compute node:

• BeoBoot partition = 2 MB

• Swap partition = half the compute node's physical memory or half the disk, whichever is smaller

• Single root partition = remainder of disk

For diskless operation, the default method of configuring the compute nodes at boot time is to run off a RAM disk. This "diskless" configuration is appropriate for many applications, but not all. Typical usage requires configuration and partitioning of the compute node hard disks, which is covered in the partitioning scenarios discussed in the following section.
