The manageability architecture also provides support for the Intel
®
Xeon Phi™
coprocessor in Node Manager mode, which adds functionality such as setting power
throttle threshold values and time windows.
In operational mode, the SMC monitors power and temperatures within the Intel
®
Xeon
Phi™ coprocessor and through sensors located on the PCI Express* card. This
information is then used to control the power consumed by the PCI Express* card and
the rotating speed of the fan(s) within the PCI Express* card cooling system. The SMC
provides status information (temperature, fan speed, and voltage levels) to the Intel
®
Xeon Phi™ coprocessor drivers, which then can be provided to the end user via a GUI.
The SMC provides a master/slave SMBus (using the IPMI IPMB protocol) so that a
platform BMC or ME can control the SMC.
The SMC on the Intel
®
Xeon Phi™ coprocessor has the following capabilities:
• General manageability features
• Board ID and SKU definition
• Unique identifying number
•Fan Control
—Read fan RPM
• Thermal throttling and throttle monitoring
— Force throttling of the coprocessor
— Monitor time in throttled state
— Separated status if power throttle threshold throttling vs. over-temperature
throttling
• Card-level power throttle threshold/capping
— Power Throttle Threshold Values 0 and 1, tracked over separate time windows
