mpssinfo

Name

mpssinfo — Provide information about current Intel(R) Xeon Phi(TM) coprocessor hardware and driver.

Synopsis

mpssinfo [OPTIONS]

DESCRIPTION

The mpssinfo command displays information about the Intel® Xeon Phi™ coprocessors installed on the system along with relevant details about the uOS and the driver.

Note

Certain device information will be unavailable when running mpssinfo as a non-root user.

OPTIONS

-h, --help [=[device|list|version]]

Display command help.

-l, --list

List all Intel® Xeon Phi™ coprocessors detected.

-d <deviceNum>, --device=<deviceNum> [-g <groupname>|--group=<groupname>]

Displays information about the user-specified MIC device (determined by <deviceNum>). To display information about all the available coprocessors, all may be specified in place of the coprocessor device number. The user may additionally specify the type of information with the --group option.

-g <groupname>, --group=<groupname>

Allows printing only a subset of the coprocessor information. If the --group option is not given, all groups are displayed. Note: if no coprocessor device number is specified, it will display the requested group information for all the available coprocessors.

Valid values for <groupname> are:

version: Show Flash and uOS versions. Show SMC boot loader version (SMC versions 1.9 and later). For earlier SMC versions, the SMC boot loader version is reported as "Not Available".
board: Show Intel® Xeon Phi™ coprocessor related information
core: Show number of cores, voltage and frequency
thermal: Show fan and thermal related data
gddr: Show coprocessor memory related information
all: Show all groups (default when group option is not specified)

All groups for all devices are displayed if mpssinfo(1) is run without any arguments.

--version Display the tool version.

Prefixes are accepted for options and group names. For example, the following commands are valid:

mpssinfo --dev 0
mpssinfo --dev 0 --group ver

EXAMPLES

Example 1. Listing Devices

The following will print all Intel® Xeon Phi™ coprocessors detected on the system, providing the device ID, PCI bus number, PCI device number and hardware ID of each coprocessor.

Below is example output taken from a system with two coprocessors installed:

$ mpssinfo --list

List of Available Devices

deviceId | bus# | pciDev# | hardwareId
---------|------|---------|-----------
       0 |   83 |       0 |   225D8086
       1 |   84 |       0 |   225C8086
--------------------------------------

Example 2. Print all info groups for a device

The following will print all info for the mic1 coprocessor present on the system:

$ mpssinfo --device=1
