is it possible to choose your processor (P or E) to run your program?

At a first "approximation" you shouldn't need to choose.

If your app would receive a 50% throughput boost from running on P cores — over some non-trivial period of time — the system is going to work that out on the fly and move your processing into a P core.

Conversely, if the system doesn't move your app out of E cores — over some non-trivial period of time — then it's decided that you wouldn't actually get meaningful benefits from a P core, so you may as well stay in the E core.

Benchmarking for its own sake would make this a more complicated scenario, but I think the question is whether comparing a "pure" P benchmark against a "pure" E benchmark gives any useful information. Probably not! What would you do with that information?

hi, I want to check the effecient of my algorithm.

only p-cores :

speedup :

2 cores : x2,03

4 cores : x3,86

6 cores : x5,65

seems very good

with E-cores

8 cores : x6,48

10 cores : x7,30

12 cores : x8,18

speedup is fall
