Hi All,

The view of the Boost.MPI (for Message Passing Interface) begins
today, Sept. 6 and continues through Sept. 15.


The Message Passing Interface (MPI) is a standard interface for message
passing in high-performance parallel applications. It defines a library
interface, available from C, Fortran, and C++, for which there are many
MPI implementations. Although there exist C++ bindings for MPI, they
offer little functionality over the C bindings. The Boost.MPI library
provides an alternative C++ interface to MPI that better supports
modern C++ development styles, including complete support for user-
data types and C++ Standard Library types, arbitrary function objects
colective algorithms, and the use of modern C++ library techniques to
maintain maximal efficiency. As an example, one can concatenate the
std::strings stored on each processor with a single reduce call and
the function object std::plus<std::string>. However, if the call to
reduce is merely computing the sum of integers, the implementation
transforms into the appropriate call to MPI_Reduce. For more information
about the design of Boost.MPI, see our design philosophy.

Review questions

Please always explicitly state in your review, whether you think the
library should be accepted into Boost.

You might want to comment on the following questions:

- What is your evaluation of the design?
- What is your evaluation of the implementation?
- What is your evaluation of the documentation?
- What is your evaluation of the potential usefulness of the library?
- Did you try to use the library? With what compiler?
   Did you have any problems?
- How much effort did you put into your evaluation? A glance? A
   quick reading? In-depth study?
- Are you knowledgeable about the problem domain?
