See the taskset utility.  Should be exactly what you're looking for. 

Putting Linux processes on certain CPU cores
I finished migration from 5.1 to 5.6, and (with the same queries as before) mysql complains right away about:


  General error: 1651 Query cache is disabled; restart the server with
  query_cache_type=1 to enable it


I don't want the query cache enabled (that's an app with lots of writting), and my file my.ini looks like this:

# The MySQL server
[mysqld]
# ... other parameters...

query_cache_type = 0
query_cache_size = 0


Also, on connect, my php connection wrapper always executes 

SET SESSION query_cache_type = OFF


What I don't understand is 


Why the parameters apparently do not work
Why does mysql even have to complain about a parameter that is disabled when it is the user's choice to do so.


Enlightment needed - Thanks!
