task scheduling based on slots in Hadoop

Hi,
Can anyone throw some more light on resource based scheduling in Hadoop.
Specifically, are resources like CPU, Memory partitioned across slots?
>From the blog by Arun on capacity scheduler,
http://developer.yahoo.com/blogs/hadoop/posts/2011/02/capacity-scheduler/
I understand that memory is the only resource supported, does that mean both
memory and CPU are partitioned across map/reduce tasks in slots?

Thanks in advance.
