Charm++ parallel programming system

These files contain ld stats information which includes the load of processors, the object load, communication information as well as mapping. So if you just want to see the stats, you can use it in simulation mode with +balancer CentralLB and it will print out those stats. That is how you can see them. IF you want to try out other load balancers, you can pass in that specific load balancer. Details are given here in the manual.

Hi Harshitha,

Thanks for your answer. But, what information have in dats files? How can I use them?

Hi Roberto,

For simulation, you can run it in simulation mode +LBSim (link to the manual). Here you can specify any load balancing strategy. If you want to just see the stats, you can link with CentralLB and it will just print out the stats. You don't need to run your original program, it can be any other charm program.

I am trying simulate by using LBDump,  LBSteps according the 20.1 section from charm manual and lbsim.dat files are generated correctly. But how I should open these files?  I tried open them by projections but doesn't work. Is there a specific software for this?
