The information in this appendix applies only to cluster platforms with a Quadrics QsNetII interconnect.
During the processing of the cluster_config utility, the swmlogger gconfig script prompts you to supply the network type of your system. The network type reflects the maximum number of ports the switch can support. The network type is used to create the qsnet diagnostics database. The Quadrics diagnostic database utilities will not work properly if you specify an incorrect network type.
Quadrics currently supports the following network types: QMS8, QMS16, QMS32, QMS64, QMS128, QMF256, and QMF1024, where the digits represent the maximum number of ports.
Follow this procedure to determine your network type:
View the following file to determine the NumLevels value:
# cat /proc/qsnet/elan4/device0/position
NodeId 7
NumLevels 2
NumNodes 16 |
Use the information shown in Table G-1 to determine your network type based on the NumLevels value you obtained in the previous step and the maximum number of ports in your switch.
Table G-1 Network Type Based on System Topology
| NumLevels Value | Network Type |
|---|
| 1 | QMS8 |
| 2 | QMS16 |
| 2 | QMS32 |
| 3 (this is a 64-way full bandwidth system) | QMS64 |
| 3 (this is a 128-way reduced bandwidth system) | QMS128 |
| 4 | QMF256 |
| 5 | QMF1024 |
