Kernet tuning docs

Tech-j — Mon, 18 Jul 2011 05:31:14 GMT

I will search the knowledge base if they are available there. Are there any specific tuning docs. for ensuring cores are used by threads to ensure load is distributed properly ? How does a Java thread map internally to ensure this ?

I don't think there are any kernel parms to do this. You may have to code this yourself with pset functions like pset_ctl(2).

If using java, you need to trust that java is doing the right thing.

I also think that the JVM should do this.

Is there a way to tune the kernel to migrate the internal threads across various cores ? There was a reference to this type of tunability during our interactions.

I was thinking the reference is to something similar to http://java.sun.com/docs/hotspot/threads/threads.html

General kernel tuning docs. are in the knowledgebase, I think.
