#2882: Running BBH with CarpetX with CPUs: High memory consumption and low performance

 Reporter: Alejandra Gonzalez
   Status: new
Milestone: 
  Version: 
     Type: bug
 Priority: major
Component: CarpetX

Comment (by Roland Haas):

My only suggestion would be to make sure that the different threads are not all tied to the same CPU core. The Marenostrum docs may have examples for this. You could also try and see if adding 

```
ActiveThorns = SystemTopology
```

would help since it will forcefully adjust the thread binding at runtime.
