C++2MPI: a software tool for automatically generating MPI datatypes from C++ classes

Efficient automated marshaling of C++ data structures for MPI applications

“…However, a comparison of our work with other directly related approaches, such as MPI Pre-Processor [28], AutoMap/AutoLink [11], or C++2MPI [14], is impossible due to their lack of support for C++ language features or even C++ itself.…”

“…These approaches include both automatic tools and special purpose libraries. The automatic tools that we consider closely related work include AutoMap/AutoLink [11], C++2MPI [14], and MPI Pre-Processor [28]. In addition, Boost.MPI and Boost.Serialization [17] provide library support for seamless marshaling and unmarshaling.…”

“…C++2MPI [14] and MPI Pre-Processor [28] provide automatic creation of MPI Datatype's for C/C++ data structures. An MPI Datatype is a list of memory offsets describing the data to be marshaled given the base offset of a structure.…”

DaStGen—A Data Structure Generator for Parallel C++ HPC Software

“…The idea to generate MPI data types automatically is not new. Actually, it has been discussed several times in more detail including dynamic data structures and pointers (see the tools MPIECC [11] or C++2MPI [5], e.g.). Nevertheless, our restricted but much simpler solution fits perfectly into the concept of a precompiler reducing memory requirements, our solution allows for exchange of a subset of an object's attributes, and the resulting code comes along without requiring for additional libraries and tools.…”

MPI Pre-Processor: Generating MPI Derived Datatypes from C Datatypes Automatically

“…In other words, this software tool does not work for any C datatype definition. C++2MPI [7] is a software tool developed as part of PGMT (for Processing Graph Method Tool) to provide the MPI derived datatype associated to a C++ class. The enduser specifies classes to deal with by means of pragma directives inserted before the definition of the corresponding classes.…”
