Charm++ parallel programming system

For first question, that function is called on each PE.  

For second, there are a few seed load balancer, rand, neighbor work stealing .  Load balancing is called when creating a chare , periodically or when PE is idle.  

You can also change period time , which is controlled by a command parameter.  Now there is no external interface to call balancer, but it should be not hard to add.

Hey,
I was just starting to design a seed balancer in converse. I have read the converse manual and am using the cldb.test.c code as a reference. Id be grateful if someone could clear the following doubts which I could not answer from the manual:

1. Is the cldb seed balancer a centralised entity or is there one copy on each processing element (PE), like with chares nodes in a charm++ load balancer?  For eg. the seed balancer uses the CldEnqueue() method to determine how to handle each message depending on the destination of the message. So, is this method run on every PE or is it a central entity?

2.  I know that the seed balancer is invoked from a charm++ program whenever a new chare is created ( cknew() ). However, is there any other manner in which I can explicitly invoke the seed balancer ? Either from my program or during run time command line parameters?

Thank you in advance,
Hrushit
