Charm++ parallel programming system

If you broadcast a ckdestroy() entry method invocation to the whole group, the element on each PE will be destroyed. I should double check, but I really hope we special-case that so that one cannot call ckdestroy() on just a single group element.

Code for this should look something like

CProxy_MyGroup groupProxy;

// . . . 

groupProxy.ckDestroy();

Hi folks,

Here is a potentially easy question that I nevertheless fail to answer based on the online documentation.

If I no longer need a chare group, how do I delete all of its elements? (The goal is to call its destructors, thus freeing up memory.)

I see that CkDestroy() can be used to individually delete an element of a chare array and I presume the same might exist for groups so I can loop over them, but is there a simpler (and potentially more efficient) call to get rid of an entire group?

Thanks,

Jozsef
