NAME
PM/Myrinet Configuration File Format
DESCRIPTION
The PM/Myrinet configuration file consists of four kinds of lines (a single '#' character indicates that the rest of the line is a comment and will be ignored).
EXAMPLES
This is an example of a PM configuration file. In this example, four hosts: comp0, comp1, comp2 and comp3 are connected by two Myrinet switches. Routes between the hosts are distributed to two inter-switch links by routing specification lines.
#
# Sample configuration file
#

#
# Host specification
#  NodeNumber   Hostname                        switchNumber.portNumber
0               comp0.pccluster.org           0.0
1               comp1.pccluster.org           0.1
2               comp2.pccluster.org           1.0
3               comp3.pccluster.org           1.1

#
# Switch specification
#  switch       switchNumber.portNumber         switchNumber.portNumber
switch          0.2                             1.2
switch          0.3                             1.3

#
# Routing specification
# search        switchNumber                    portNumber ...
search          0                               0 2 1 3
search          1                               0 2 1 3

#
# End of configuration
#
Here is the same configuration defined with symbolic switch names and M2M-OCT-SW8 switch types:
#
# Sample configuration file
#

#
# Symbolic switch specification
#  SymbolicSwitchName   SwitchType
sw0                     M2M-OCT-SW8
sw1                     M2M-OCT-SW8

#
# Host specification
#  NodeNumber   Hostname                         SymbolicSwitchName.PortName
0               comp0.pccluster.org           sw0.0,0
1               comp1.pccluster.org           sw0.0,1
2               comp2.pccluster.org           sw1.0,0
3               comp3.pccluster.org           sw1.0,1

#
# Switch specification
#  switch       SymbolicSwitchName.PortName     SymbolicSwitchName.PortName
switch          sw0.4,4                          sw1.4,4
switch          sw0.5,4                          sw1.5,4

#
# End of configuration
#
FILES
/opt/score/etc/pm-myrinet.cnf
NOTES
Symbolic and number notation should not be used interchangeably in the same configuration file to avoid switch number conflicts. This is because the switch number is automatically assigned for the symbolic switch notation.

If symbolic switch names are defined and multiple routes are available between switches, a route search order cannot be set. The route search order policy will be determined automatically by the M2M-OCT-SW8 switch type.
