Create
sci_config.hpc
The SCI configuration procedure reads network mapping information from the
configuration file
/opt/SUNWsma/sci_config.hpc
, which you create.
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.
4 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.
4 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.
4
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.
4
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.
4
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
.
Editing a Configuration Template
Copy the applicable template to
/opt/SUNWsma/sci_config.hpc
. For example, to
create a configuration file for the two-node striped topology,
# cd /opt/SUNWsma # cp /opt/SUNWhpc/bin/Install_Utilities/config_dir/sma2-2stripes.hpc sci_config.hpc
Use the
sma4-2stripes.hpc
template for creating a three-node, striped
configuration.
