Hi all,

Is there a clean way to change a scheduler's event frequency on the fly?

Browsing the API, I see two possibilities:

• set it when the scheduler is first created (using ABT_sched_basic_freq?)
• set it dynamically by manipulating the ABT_sched_get_data() pointer, but this seems especially dangerous since the sched data struct definition isn't public (i.e. it could cause memory corruption if the internal struct def changed)
  

For some context (in case there is a different way to go about this entirely), I'm trying to figure out how to get ABT_info_trigger_print_all_thread_stacks() to print information more quickly, which IIUC relies on getting the active schedulers to call get_events() sooner.

I'm happy to add some explicit ABT_thread_yield() shortly after the ABT_info_trigger_print_all_thread_stacks() to at least get the calling ES to execute it's scheduler loop immediately, but I think that won't matter much if it doesn't trip the frequency counter when I do it.

Without this (at least with the _wait scheduler and threads that are occasionally tied up in system calls) I think the stack dump is likely to trigger too late to display what I'm hoping to capture when I call it.  The first example I tried appeared to essentially defer dump until shutdown.

thanks!
