Skydel simulator latecy spikes

[scaliari]

Problem
Occasional latency spikes cause a “streaming underflow” fatal error that stops the simulation.

All spikes are periodic:

(I have performace.csv but I cannot update in this request).

When it happens
It occurs in every configuration we use—NoneRT, SDR, and HIL.

Setup
Hardware: GSG‑8 simulator
Software: runs only Skydel Simulator and Chrony for external time sync.

Note
After Skydel restart the amplitude of the spikes is less.

Do you have any idea about the root causes of this problem?

Hi @scaliari ,

So two things to try here that might be causing this.

Firstly, it’s possible the GPU is being taxed by another application. The most common culprit might be something like TeamViewer. That might be causing the spike.

The second thing our dev team recommended is to increase the latency – unless it needs to be that low. Try setting it at 200ms to see if that helps the stability.

Let us know!
