Charm++ parallel programming system

CkArrayOptions actually conveys the number of initial elements requested. We made that shift from an int to allow for any dimensions (and stride, actually, for sparse regular arrays). We apparently neglected to note that was a public API. We'll definitely update the documentation.

If it fits, we may also add a suitable overload to restore compatibility with the older documented behavior.

Thanks for a good question.

Hi folks,

I've just updated to 6.7.1 and have some code for custom array element placement using map objects that now breaks and I'm not sure how to fix it.

I used to override CkArrayMap's populateInitial() with

void populateInitial( int, CkArrayIndex& idx, void *msg, CkArrMgr *mgr ) override;

which now breaks, because it expects CkArrayOptions& as its 2nd argument:

ck-core/cklocation.h, line 96:

virtual void populateInitial(int arrayHdl,CkArrayOptions& options,void *ctorMsg,CkArrMgr *mgr);

The documentation, however, now recommends using

virtual void populateInitial(int arrayHdl, int numInitial, void *msg, CkArrMgr *mgr)

but the only overload in CkArrayMap is the one accepting CkArrayOptions& as its 2nd argument above.

How should I get the number of initial elements in my override of populateInitial()?

Thanks,

Jozsef
