5.5.5 AMD CPU Systems (additions for Lustre/GPFS over verbs
RDMA)
One of the following parameters sets up the QLogic driver to accomplish these settings for
Lustre/GPFS over verbs RDMA. For single-port Host Channel Adapters, the line would look
like one of the following, according to the core and CPU type of the node:
For 8-core, AMD Barcelona or Shanghai, nodes:
options ib_qib singleport=1 krcvqs=8 rcvhdrcnt=4096
For 12-core or 24-core, AMD Opteron nodes:
options ib_qib singleport=1 krcvqs=4 rcvhdrcnt=4096
To modify the previous options ib_qib line examples for two-port Host Channel Adapters
(for example, QLE7342), divide the krcvq parameter by the number of active ports on the
Host Channel Adapters. For example, an 8-core system would set the krcvq parameter to 4
for a dual-port adapter, and omit the single-port parameter as follows:
For 8-core, dual HCA port (e.g. Intel Nehalem/QLE7342) nodes:
options ib_qib pcie_caps=0x51 krcvqs=4 rcvhdrcnt=4096
5.6 New Features
QLogic OFED+ Host software package version 6.0.2.1.11 does not have any new features.
QLogic OFED+ Host software package version 6.0.2.0.28 includes the following new
features:
OFED has been upgraded to version 1.5.2.
iSCSI extensions for RDMA (iSER) no longer requires an update to the iSCSI RPMs
supplied with the distro. When installing iSER, the iSCSI RPMs will not be updated by
the installer.
InfiniBand-Bonding is now separately selectable in the install menus. When planning
to use Ethernet bonding, but not IPoIB bonding, QLogic recommends using the
bonding driver supplied with the distribution.
For forward compatibility command line installations, selecting ipoib will continue to
install IPoIB and InfiniBand bonding. When selecting ofed_ipoib, only IPoIB will be
installed. To explicitly select InfiniBand bonding, select ofed_ib_bonding.
QLogic OFED+ Host software package version 6.0.1.1.3 includes the following new feature:
Platform Cluster Manager has been upgraded to version 2.0.1.
