Introduction to low-level power-saving and monitoring techniques
The second webinar of the Energy Efficient Computing series, Introduction to low-level power-saving and monitoring techniques on x86 systems and idle-power optimization on HPC systems, will take place on 23 February 2024 from 14:00 - 15:00 CET.
Hardware vendors implement various power-saving mechanisms to conserve power and prevent overheating. In the first part of this webinar, Robert Schöne from TUD Dresden University of Technology will explain the power-saving mechanisms used by x86 systems and how user codes can influence them. Additionally, he will discuss updates in Intel power monitoring interfaces that should be taken into consideration. In the second part, Thomas Ilsche from TUD Dresden University of Technology will discuss the different factors that affect idle power consumption and provide methodologies and tools for identifying and resolving issues. The presentation will follow a narrative approach based on insights gained during the acceptance phase of a 630-node CPU system.
