Description
As Fermilab's representatives to the C++ standardization effort, we have
been promoting directions of special interest to the physics community.
We here report on selected recent developments toward the next revision
of the C++ Standard. Topics will include standardization of random
number and special function libraries, as well as core language issues
promoting improved run-time performance.
The random number library provides an extensible framework for random
number generators. It includes a handful of widely-used and high-quality
random number engines, as well as some of the most widely-used random
number distributions. The modular design makes it easy for users to add
their own engines, and perhaps more importantly their own distributions,
on an equal footing with those in the library.
The special functions library contains many of the commonly-used
functions of mathematical physics. These include a variety of
cylindrical and spherical Bessel functions, Legendre and associated
Legendre functions, hypergeometric and confluent hypergeometric
functions, among others.
We also report on an ongoing analysis, and proposal for core language
additions, with the goal of improved run-time performance. Current
compilers routinely perform inter-procedural flow analysis within a
compilation unit. These additions would allow compilers to perform
comparable analysis between compilation units, and to optimize code
based on their findings.
