%description
Threading Building Blocks (TBB) is a C++ runtime library that
abstracts the low-level threading details necessary for optimal
multi-core performance. It uses common C++ templates and coding style
to eliminate tedious threading implementation work.

TBB requires fewer lines of code to achieve parallelism than other
threading models. The applications you write are portable across
supported platforms. Since the library is also inherently scalable, no
code maintenance is required as more processor cores become available.

%description -l pl.UTF-8
Threading Building Blocks (TBB) to biblioteka uruchomieniowa C++
abstrahująca niskopoziomowe szczegóły obsługi wątków potrzebne dla
optymalnej wydajności na procesorach wielordzeniowych. Wykorzystuje
szablony C++ w celu wyeliminowania nudnej pracy nad wielowątkowością.

TBB wymaga mniej linii kodu do osiągnięcia równoległości niż inne
modele wątkowania. Aplikacje są przenośne między obsługiwanymi
platformami. Biblioteka jest skalowalna, więc nie jest wymagane
modyfikowanie kodu wraz z dostępnością większej liczby rdzeni
procesor.
