Sorry, I meant that the method invoking Work::reduce() should be threaded.

Just to make sure, you mean that the caller needs to be threaded, but Work::reduce() does not, since it is being called, right? And the reason is that the RTS would block otherwise, right?

As long as work::reduce is a threaded entry method, this is ok. The destructor of the resume thread callback suspends the thread in which it is invoked, which is why you must label the calling entry method as threaded.

Hi,

is it ok to use a CkCallbackResumeThread() as a reduction client?

CProxy_Work A = CProxy_Work::ckNew();

A.reduce(CkCallbackResumeThread());

void Work::reduce (CkCallback &cb)

{

  /* .... */

  contribute(cb);

}

Thanks,

nick
