I have 4 different multithreaded parallel workloads. I want to profile them based on the amount of serial parts they have. Is there any ways to estimate the amount of serial part in a parallel program? Which metric can represent it more efficiently?

Thanks and regards

If you want to measure the serial part (or any other metric), first you should adopt a parallel model. Using one model, you can obtain different metrics.

I recommend you the Dynamic Multi-threading Model. It's described here.
