Estimating processor usage

A method of operating a computing device having a simultaneous multi-threading (SMT) processor comprising:

• obtaining samples comprising reported processor usage for the SMT processor;
• determining an estimated number of threads corresponding to each of the samples;
• calculating an adjustment factor based at least on the samples and the estimated number of threads;
• determining an actual processor usage estimate for the SMT processor by adjusting the reported processor usage by the adjustment factor;
• and
• executing, by the SMT processor, a number of threads, wherein the number of threads is based on the determined actual processor usage estimate.

A computer-readable code stored on a non-transitory computer readable medium, which when executed causes a simultaneous multi-threading (SMT) processor to:

• obtain samples comprising reported processor usage for the SMT processor;
• determine an estimated number of threads corresponding to each of the samples;
• calculate an adjustment factor based at least on the samples and the estimated number of threads;
• determine an actual processor usage estimate for the SMT processor by adjusting the reported processor usage by the adjustment factor;
• and
• execute a number of threads, wherein the number of threads is based on the determined actual processor usage estimate.
