Detailed Description

Function Documentation

template<typename T , typename M >

GlobalAddress< M > global_pointer_to_member ( const GlobalAddress< T >  t, const M T::*  m  )

inline

computes offsets of members in structs and claases call like this:

struct Foo {
  int i;
} foo;
GlobalAddress< Foo > foo_gp = make_global( foo );
GlobalAddress< int > foo_i_gp = global_pointer_to_member( foo_gp, &Foo::i );

template<typename T >

LocalIterator<T> iterate_local	(	GlobalAddress< T >	base,
		size_t	nelem
	)

Helper for iterating over local elements of a Linear address range.

auto array = global_alloc<long>(N);
on_all_cores([]{
  for (auto& v : iterate_local(array,N)) {
    v++;
  }
});
