Description

The LB Database should not collect comm info unless a balancer that is running actually uses it. For PDES and fine-grained communication intensive applications the overhead of lb comm info collection is huge.

History

#1 Updated by Kavitha Chandrasekar 7 months ago

  • Status changed from New to In Progress

I have added the ability for LB's to specify the commStatsOn, and have removed it from command line options. There are over 10 LBs that need this option, so I am adding the option from the LB's currently.
