Barrier (computer science)

In parallel computing, a barrier is a type of synchronization method. A barrier for a group of threads or processes in the source code means any thread/process must stop at this point and cannot proceed until all other threads/processes reach this barrier.

Many collective routines and directive-based parallel languages impose implicit barriers. For example, a parallel do loop in Fortran with OpenMP will not be allowed to continue on any thread until the last iteration is completed. This is in case the program relies on the result of the loop immediately after its completion. In message passing, any global communication (such as reduction or scatter) may imply a barrier.

Barrier (video game)

Barrier is a maze arcade game using vector graphics released by Vectorbeam in 1979. In this very basic game, players move a small triangle around on the grid, while attempting to avoid the diamonds that are also moving around on the grid. Reaching the end of the grid teleports the player back to the front of the grid to gain points. The game is played on a 3x9 grid that is displayed at angle to make it appear to be in 3-D. The game was sold to Vectorbeam by Cinematronics.
