Q

If you need to find which InfiniPath and OpenFabrics modules are running, try the 
following command:

# lsmod | egrep ’ipath_|ib_|rdma_|findex’

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

To check the contents of an RPM, use these commands:

$ rpm -qa infinipath\* mpi-\*

$ rpm -q --info infinipath # (etc)

The option-q will query and --qa will query all.

Check the file 

status_str 

to verify that the InfiniPath software is loaded and 

functioning. To locate this file go to:

/sys/bus/pci/drivers/ib_ipath/

and look for a subdirectory with the InfiniPath unit numbers 00, 01, and so on. 

status_str

 will be found in this directory.
