%description
Threading Building Blocks (TBB) offers a rich and complete approach to
expressing parallelism in a C++ program. It is a library that helps you take
advantage of multi-core processor performance without having to be a threading
expert. Threading Building Blocks is not just a threads-replacement library. It
represents a higher-level, task-based parallelism that abstracts platform
details and threading mechanism for performance and scalability.

%description -n libtbbmalloc%{so_ver}
This subpackage contains the two TBB memory allocator templates that
are similar to the STL template class std::allocator. These two
templates, scalable_allocator<T> and cache_aligned_allocator<T>,
address critical issues in parallel programming: scalability and
false sharing.
