|
||
* Bitwise and reducers allow the computation of the bitwise and of a set of
|
||
* values in parallel.
|
||
*
|
||
* @ingroup Reducers
|
||
*
|
||
* You should be familiar with @ref pagereducers "Cilk reducers", described in
|
||
* file `reducers.md`, and particularly with @ref reducers_using, before trying
|
||
* to use the information in this file.
|
||
*
|
||
* @section redopand_usage Usage Example
|
||
*
|
||
* cilk::reducer< cilk::op_and<unsigned> > r;
|
||
* cilk_for (int i = 0; i != N; ++i) {
|
||
* *r &= a[i];
|
||
* }
|
||
* unsigned result;

* r.move_out(result);
|
||
*
|
||
* @section redopand_monoid The Monoid
|
||
*
|
||
* @subsection redopand_monoid_values Value Set
|
||
*
|
||
* The value set of a bitwise and reducer is the set of values of `Type`,
|
||
* which is expected to be a builtin integer type which has a representation
|
||
* as a sequence of bits (or something like it, such as `bool` or
|
||
* `std::bitset`).
|
||
*
|
||
* @subsection redopand_monoid_operator Operator
|
||
*
|
||
* The operator of a bitwise and reducer is the bitwise and operator, defined
|
||
* by the “`&`” binary operator on `Type`.
|
||
*
|
||
* @subsection redopand_monoid_identity Identity
|
||
*
|
||
* The identity value of the reducer is the value whose representation
|
||
* contains all 1-bits. This is expected to be the value of the expression
|
||
* `~Type()` (i.e., the bitwise negation operator applied to the default value
|
||
* of the value type).
|
||
*
|
||
* @section redopand_operations Operations
|
||
*
|
||
* @subsection redopand_constructors Constructors
|
||
*
|
||
* reducer() // identity
|
||
* reducer(const Type& value)
|
||
* reducer(move_in(Type& variable))
|
||
*
|
||
* @subsection redopand_get_set Set and Get
|
||
*
|
||
* r.set_value(const Type& value)
|
||
* const Type& = r.get_value() const
|
||
* r.move_in(Type& variable)
|
||
* r.move_out(Type& variable)
|
||
*
|
||
* @subsection redopand_initial Initial Values
|
||
*
|
||
* If a bitwise and reducer is constructed without an explicit initial value,
|
||
* then its initial value will be its identity value, as long as `Type`
|
||
* satisfies the requirements of @ref redopand_types.
|
||
*
|
||
* @subsection redopand_view_ops View Operations
|
||
*
|
||
* *r &= a
|
||
* *r = *r & a
|
||
* *r = *r & a1 & a2 … & an
|
||
*
|
||
* @section redopand_types Type and Operator Requirements
|
||
*
|
||
* `Type` must be `Copy Constructible`, `Default Constructible`, and
|
||
* `Assignable`.
|
||
*
|
||
* The operator “`&=`” must be defined on `Type`, with `x &= a` having the
|
||
* same meaning as `x = x & a`.
|
||
*
|
||
* The expression `~ Type()` must be a valid expression which yields the
|
||
* identity value (the value of `Type` whose representation consists of all
|
||
* 1-bits).
|
||
*
|
||
* @section redopand_in_c Bitwise And Reducers in C
|
||
*
|
||
* The @ref CILK_C_REDUCER_OPAND and @ref CILK_C_REDUCER_OPAND_TYPE macros can
|
||
* be used to do bitwise and reductions in C. For example:
|
||
*
|
||
* CILK_C_REDUCER_OPAND(r, uint, ~0);
|
||
* CILK_C_REGISTER_REDUCER(r);
|
||
* cilk_for(int i = 0; i != n; ++i) {
|
||
* REDUCER_VIEW(r) &= a[i];
|
||
* }
|
||
* CILK_C_UNREGISTER_REDUCER(r);
|
||
* printf("The bitwise AND of the elements of a is %x\n", REDUCER_VIEW(r));
|
||
*
|
||
* See @ref reducers_c_predefined.
