Abstract
A method and system of managing operating system (OS) jitter are provided. Power consumption information is received for a first time period of a compute node of the plurality of compute nodes of a large-scale computing system, wherein the compute node is running a subject program. A digital signature of a power spectrum of the compute node is determined based on the power consumption information. The digital signature of the power spectrum is compared to a baseline power spectrum. Upon determining that the digital signature of the power spectrum varies beyond a threshold from the baseline power spectrum, the subject program is identified as a source of incompatible OS jitter. An OS jitter mitigation measure is performed. Upon determining that the digital signature of the power spectrum does not vary beyond the threshold from the baseline power spectrum, the digital signature of the power spectrum is stored in a memory.
