If you want to restart the QLogic VNIC interfaces, run the following
command:
# /etc/init.d/qlgc_vnic restart
You can get information about the QLogic VNIC interfaces by using the following
script (as root):
# ib_qlgc_vnic_info
This information is collected from the
/sys/class/infiniband_qlgc_vnic/interfaces/ directory, under which
there is a separate directory corresponding to each VNIC interface.
VNIC interfaces can be deleted by writing the name of the interface to the
/sys/class/infiniband_qlgc_vnic/interfaces/delete_vnic file. For
example, to delete interface veth0, run the following command (as root):
# echo -n veth0 >
/sys/class/infiniband_qlgc_vnic/interfaces/delete_vnic
More information for configuration, starting and stopping the interface, and basic
troubleshooting is found in the QLogic OFED+ User Guide.
MPI over uDAPL
Intel MPI can be run over uDAPL, which uses IB Verbs. uDAPL is the user mode
version of the Direct Access Provider Library (DAPL), and is provided as a part of
the OFED packages. You will also have to have IPoIB configured.
Setup for Intel MPI is described below.
1. Make sure that DAPL 1.2 (not version 2.0) is installed on every node. In this
release they are called compat-dapl. (Both versions are supplied with the
OpenFabrics RPMs.) They can be installed either with the Installer with the
QLogicIB-Basic package or with rpm with the QLogic OFED 1.4 RPM set.
They look something like this:
$ rpm -qa | grep compat-dapl
compat-dapl-1.2.12-1.x86_64.rpm
compat-dapl-debuginfo-1.2.12-1.x86_64.rpm
compat-dapl-devel-1.2.12-1.x86_64.rpm
compat-dapl-devel-static-1.2.12-1.x86_64.rpm
compat-dapl-utils-1.2.12-1.x86_64.rpm
