Hi, everyone.
I tried to run a Charm++ application with option “+balancer CentralLB”
to print the Load Balancing State. Can you help me to explain the
meaning of the data?
1. The data in Object Data segment looks like

Object 2 //are different kinds of
chares numbered unify?
id = 0 2 4 0 //what is the meaning of id?
OM id = 7 Mig. = 1
CPU = 0.004000 Wall = 0.003702
“.
2. We know that the Chare in Charm++ is migratable, and then does the
object id remain the same after migration?

3. As the data print according with LB period intervals, are the data
incremental (only the data just in that period are printed) or
accumulated from previous periods?

4. I notice that there is “receiver id = 436876768:[0 27 -1068911690
-1073741824]” in one of the Link information, but there is no such
object id in the Object Data section. What’s wrong?

My log file is attached. Thanks for your help.

Best regards.
Yours Bonan Hou
