Mixing Adapters
Within a given interconnect family, several different adapters can be supported. However,
HP requires that all adapters must be from the same interconnect family; a mix of adapters
from different interconnect families is not supported.
InfiniBand Double Data Rate
All components in a network must be DDR to achieve DDR performance levels.
Myrinet Adapters
The Myrinet adapters can be either the single-port M3F-PCIXD-2 (Rev. D) or the dual port
M3F2–PCIXE-2 (Rev. E and Rev F); mixing adapter types is not supported.
QsNet
II
The QsNet
II
high-speed interconnect from Quadrics, Ltd. is the only version of Quadrics
interconnect that is supported.
1.9 Large-Scale Systems
A typical HP XC system contains from 5 to 512 nodes. To allow systems of a greater size, an HP
XC system can be arranged into a large-scale configuration with up to 1024 compute nodes (HP
might consider larger systems as special cases).
This configuration arranges the HP XC system as a collection of hardware regions that are tied
together through a ProCurve 2848 Ethernet switch.
The nodes of the large-scale system are divided as equally as possible between the individual
HP XC systems, which are known as regions. The head node for a large-scale HP XC system is
always the head node of region 1.
