Get Started with Intel® oneAPI Threading Building Blocks (oneTBB)

Intel® oneAPI Threading Building Blocks (oneTBB) enables you to simplify parallel programming by breaking computation into parallel running tasks. oneTBB is available as a stand-alone product and as part of the Intel® oneAPI Base Toolkit.
oneTBB is a runtime-based parallel programming model for C++ code that uses threads. It consists of a template-based runtime library to help you harness the latent performance of multi-core processors. Use oneTBB to write scalable applications that:
  • Specify logical parallel structure instead of threads
  • Emphasize data parallel programming
  • Take advantage of concurrent collections and parallel algorithms

Before You Begin

After installing oneTBB, you need to set the environment variables:
  1. Go to the oneTBB installation directory (
    <install_dir>
    ). By default,
    <install_dir>
    is the following:
    • On Linux* OS:
      • For superusers (root):
        /opt/intel/oneapi
      • For ordinary users (non-root):
        $HOME/intel/oneapi
    • On Windows* OS:
      • <Program Files>\Intel\oneAPI
  2. Set the environment variables, using the script in <install_dir>, by running
    • On Linux* OS:
      vars.{sh|csh} in <install_dir>/tbb/latest/env
    • On Windows* OS:
      vars.bat in <install_dir>/tbb/latest/env
