SCI Configuration Templates

The Sun HPC ClusterTools 3.0 software release includes the following SCI configuration templates to simplify the creation of sci_config.hpc. Each template represents a supported SCI network topology.

• sma2.hpc - Two nodes connected directly by a single SCI station cable. There is no intervening SCI switch. Because this configuration uses only one network interface per node, it does not support message striping.

• sma3.hpc - Three nodes connected through an SCI switch. Each node is connected to the switch by a single station cable. Consequently, message striping is not supported.

• sma4.hpc - Four nodes connected through a single SCI switch. Each node is connected to the switch by a single station cable. Again, message striping is not supported.

• sma2-2stripes.hpc - Two nodes connected directly by two SCI station cables. There is no intervening SCI switch. Because both nodes have two network interfaces, messages can be striped across both cables.

• sma4-2stripes.hpc - Four nodes connected through two SCI switches via two station cables per node. Because each node has two network interfaces, striping is supported. Two SCI switches are needed because each switch has only four ports.

These templates are in /opt/SUNWhpc/bin/Install_Utilities/config_dir.
