Note that ipath_control will report whether the installed adapter is the QHT7040,
QHT7140, or the QLE7140. It will also report whether the driver is InfiniPath-specific
or not with the output associated with $Id.
rpm
To check the contents of an RPM, commands of these types may be useful:
$ rpm -qa infinipath\* mpi-\*
$ rpm -q --info infinipath # (etc)
The option -q will query and -qa will query all.
mpirun
mpirun can give information on whether the program is being run against a QLogic
or non-QLogic driver. Sample commands and results are given below.
QLogic-built:
$ mpirun -np 2 -m /tmp/id1 -d0x101 mpi_latency 1 0
asus-01:0.ipath_setaffinity: Set CPU affinity to 1, port 0:2:0 (1
active chips)
asus-01:0.ipath_userinit: Driver is QLogic-built
Non-QLogic built:
$ mpirun -np 2 -m /tmp/id1 -d0x101 mpi_latency 1 0
asus-01:0.ipath_setaffinity: Set CPU affinity to 1, port 0:2:0 (1
active chips)
asus-01:0.ipath_userinit: Driver is not QLogic-built
ident
ident
strings are available in ib_ipath.ko. Running ident (as root) will yield
information similar to the following. For QLogic RPMs, it will look like:
# ident /lib/modules/$(uname -r)/updates/*ipath.ko
/lib/modules/2.6.16.21-0.8-smp/updates/ib_ipath.ko:
$Id: QLogic Release2.0 $
$Date: 2006-09-15-04:16 $
$Id: QLogic Release2.0 $
$Date: 2006-09-15-04:16 $
For non-QLogic RPMs, it will look like:
# ident /lib/modules/$(uname -r)/updates/*ipath_ether.ko
/lib/modules/2.6.16.21-0.8-smp/updates/infinipath.ko:
