A synchronization mechanism applied to groups of processes, with the property that no process in the group may pass the barrier until all processes in the group have reached the barrier. In other words, processes arriving at the barrier suspend or block until all processes have arrived; they may then all proceed.
Any material or system that blocks or reduces the transmitted sound level as it passes through the material. A poor barrier material will provide a transmission loss TL 10 dB, whereas a good material will have a TL 20 dB for partial height barriers and TL 50 dB for full height barriers, at the frequencies of interest. Both STC and CAC are measures of acoustical barrier performance.

A point in a parallel program where all processors participating in the barrier synchronise, ie. block until all have reached the barrier before continuing.
(BAYR-ee-er) Something that blocks, prevents, separates, or limits.
Collective operation used to synchronize the execution of processes. MPI_Barrier blocks the calling process until all receiving processes have called it. This is a useful approach for separating two stages of a computation so messages from each stage are not overlapped.
Point of synchronization for multiple simultaneous processes. Each process reaches the barrier, and then waits until all of the other processes have reached that same barrier before proceeding.
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.
