SUMMARY="High level abstract threading library"
DESCRIPTION="Threading Building Blocks (TBB) is a C++ template library \
developed by Intel for parallel programming on multi-core processors. Using \
TBB, a computation is broken down into tasks that can run in parallel. The \
library manages and schedules threads to execute these tasks."
