Orchestrator-Based Thermal Zone Control for Heterogeneous Computing Platforms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heterogeneous computing platforms lack the ability to dynamically update thermal zones or performance settings in response to undervoltage or overcurrent conditions, leading to inefficient power management and potential system instability.
Innovation Solution
The implementation of a system and method where a heterogeneous computing platform, comprising a plurality of devices with firmware instructions, detects undervoltage or overcurrent conditions and selects an Advanced Configuration and Power Interface (ACPI) thermal zone setting without host OS involvement, using an orchestrator that compares conditions against threshold values and modifies thermal zone settings based on context or telemetry data.

1Use of energy by moving object
If conventional heterogeneous computing platforms operate without dynamic thermal zone updates, then system simplicity is maintained, but power management efficiency deteriorates and system stability is compromised
Solution Approach 1:
The orchestrator device autonomously detects undervoltage/overcurrent conditions and dynamically updates thermal zones without requiring host OS involvement or manual intervention. The system serves itself by having the orchestrator monitor power conditions and automatically adjust thermal management settings, eliminating the need for complex software stacks while improving power management efficiency.
Solution Approach 2:
The system separates thermal management control from the host OS by implementing it at the firmware/orchestrator level. This segmentation allows independent optimization of power management functions without affecting the overall system architecture, enabling efficient thermal zone updates while maintaining system simplicity.
2Reliability
If thermal zone settings are dynamically updated in response to power conditions, then system stability is improved, but response time and control complexity increase
Solution Approach 1:
The orchestrator is pre-configured with thermal zone settings and detection thresholds before runtime. When undervoltage or overcurrent conditions occur, the orchestrator can immediately apply pre-determined thermal management actions without requiring complex real-time decision algorithms, thus improving system stability while maintaining fast response times.
3Productivity
If host OS involvement is eliminated in thermal management, then system efficiency is improved, but ease of operation deteriorates
Solution Approach 1:
The orchestrator serves as an intermediary between the power management hardware and the host OS. It translates power conditions into thermal management actions independently, then communicates only essential information to the host OS. This intermediary approach maintains system efficiency by eliminating OS involvement in real-time decisions while preserving operational simplicity through standardized interfaces.

AI summary
Systems and methods for performance controls based upon the detection of undervoltage or overcurrent conditions in heterogenous computing platforms are described. In an illustrative, non-limiting embodiment, an Information Handling System (IHS) may include: a heterogeneous computing platform comprising a plurality of devices; and a memory coupled to the heterogeneous computing platform, where the memory comprises firmware instructions that, upon execution by at least one of the plurality of devices, causes the at least one device to operate as an orchestrator configured to: detect an overcurrent or undervoltage condition; and in response to the detection, select an Advanced Configuration and Power Interface (ACPI) thermal zone setting.
