The Template Numerical Toolkit (TNT) is a collection of interfaces and
|
|
reference implementations of numerical objects useful for scientific
|
|
computing in C++. The toolkit defines interfaces for basic data
|
|
structures, such as multidimensional arrays and sparse matrices, commonly
|
|
used in numerical applications. The goal of this package is to provide
|
|
reusable software components that address many of the portability and
|
|
maintenance problems with C++ codes.
|
|
TNT provides a distinction between "interfaces" and "implementations" of
|
|
TNT components. For example, there is a TNT interface for two-dimensional
|
|
arrays which describes how individual elements are accessed and how
|
|
certain information, such as the array dimensions, can be used in
|
|
algorithms; however, there can be several implementations of such an
|
|
interface: one that uses expression templates, or one that uses BLAS
|
|
kernels, or another that is instrumented to provide debugging
|
|
information. By specifying only the interface, applications codes may
|
|
utilize such algorithms, while giving library developers the greatest
|
|
flexibility in employing optimization or portability strategies.
