Hello!

As I opened my Task-Manager up, I saw strange Diagrams in the CPU Load caused
by SETI. I just want to share it with you here, that´s why the Forum is there for isn´t it? :)

FOR SETI. FOR US. FOR THE FUTURE.

Hey Edwin,
I see similar effects in a different context, namely experiments with GPU utilisation loading GPUs differently under both Cuda and OpenCL.

What I traced that behaviour to may have a similar source here, basically a interference pattern between the sampling rate of the monitoring program, versus a regular frequency of the device being loaded.

My guess is that either underlying hardware, settings or drivers are regulating your CPU usage.

Assuming you are not explicitly throttling with some application like TThrottle, Intel Speedstep or AMD Cool 'n Quiet, I would look at possible issues like CHipset driver and device quality, using for example DPC latency checker.

You might find that simply changing the sampling rate in task manager will eliminate the patterns (in which case they were pure mathematical sampling artefacts rather than real) or they change, or even disappear if you use a different tool like process explorer.

Patterns like that are a good indication there is some delay or frequency in the source that 'beats' with the monitoring timer.
