The Linda model provides a distributed shared memory, known as a tuple space because its basic addressable unit is a tuple, an ordered sequence of typed data objects; specifically in Linda, a tuple is a sequence of up to 16 typed fields enclosed in parentheses". The tuple space is "logically shared by processes" which are referred to as workers ...
The variadic template feature of C++ was designed by Douglas Gregor and Jaakko Järvi [1] [2] and was later standardized in C++11. Prior to C++11, templates (classes and functions) could only take a fixed number of arguments, which had to be specified when a template was first declared. C++11 allows template definitions to take an arbitrary ...
C++11 was published as ISO/IEC 14882:2011 [5] in September 2011 and is available for a fee. The working draft most similar to the published C++11 standard is N3337, dated 16 January 2012; [6] it has only editorial corrections from the C++11 standard. [7] C++11 is fully supported by Clang 3.3 and later. [8]
In fact, this algorithm is essentially a special-case of the classic hash join algorithm. [ citation needed ] The block nested loop runs in O ( P r P s / M ) {\displaystyle O(P_{r}P_{s}/M)} I/Os where M {\displaystyle M} is the number of available pages of internal memory and P r {\displaystyle P_{r}} and P s {\displaystyle P_{s}} is size of R ...
The use of templates as a metaprogramming technique requires two distinct operations: a template must be defined, and a defined template must be instantiated.The generic form of the generated source code is described in the template definition, and when the template is instantiated, the generic form in the template is used to generate a specific set of source code.
A tuple space is an implementation of the associative memory paradigm for parallel/distributed computing. It provides a repository of tuples that can be accessed concurrently. As an illustrative example, consider that there are a group of processors that produce pieces of data and a group of processors that use the data.
Although std::map is typically implemented using a self-balancing binary search tree, C++11 defines a second map called std::unordered_map, which has the algorithmic characteristics of a hash table. This is a common vendor extension to the Standard Template Library (STL) as well, usually called hash_map , available from such implementations as ...
The C++ Standard Library also incorporates most headers of the ISO C standard library ending with ".h", but their use was deprecated (reverted the deprecation since C++23 [2]). [3] C++23 instead considers these headers as useful for interoperability with C , and recommends against their usage outside of programs that are intended to be both ...
