One last question. If I have an AMPI code that I have linked with commonLB and that I run with a valid +balancer argument, but I do not call AMPI_Migrate anywhere in the code, does the runtime still collect load balance information? If so, is there a charmrun command that I can give that prevents the runtime from doing that? I know I could use these functions:

AMPI_Load_stop_measure(void)

AMPI_Load_start_measure(void)

but I prefer to specify it on the command line (otherwise I need to supply yet another input parameter and parse it in the code). Thanks!

 

If you run the program with +LBOff, instrumentation will be initially disabled. It will be as if Load_stop_measure() were called at the beginning of execution.
