1. Barrier

   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 may imply a barrier. Classic barrier constructs define the set of participating processes/threads statically. This is usually done either at program startup or when a barrier like the Pthreads barrier is instantiated. This restricts the possible applications for which barriers can be used. To support more dynamic programming paradigms like fork/join parallelism, the sets of participants have to be dynamic. Thus, the set of processes/threads participating in a barrier operation needs to be able to change over time. X10 introduced the concept of clocks for that purpose, which provide a dynamic barrier semantic. Building on clocks, phasers have been proposed to add even more flexibility to barrier synchronization. With phasers it is possible to express data dependencies between the participating processes explicitly to avoid unnecessary over-synchronization.

1. barrier

   In a general sense means any fortification or strong place on the frontiers of a country. It is likewise a kind of fence composed of stakes and transoms, as over-thwart rafters, erected to defend the entrance of a passage, retrenchment, or the like. In the middle of the barrier is a movable bar of wood, which is opened or shut at pleasure. It also implies a gate made of wooden bars, about 5 feet long, perpendicular to the horizon, and kept together by two long bars going across and another crossing diagonally. Barriers are used to stop the cut made through the esplanade before the gate of a town.

As per a separate agreement, it will implement the recommendations made by the national transportation safety board in the wake of the gas explosions in Massachusetts two years ago. SUPREME COURT HEARS ATLANTIC COAST PIPELINE CASE, ROBERTS WARNS OF IMPERMEABLE BARRIER ALONG APPALACHIAN TRAIL Columbia Gas, through a pattern of flagrant indifference, in the face of extreme risk to life and property, knowingly violated minimum safety standards for starting up and shutting down gas pipelines, Shoemaker said. Federal investigators blamed the explosions on over-pressurized gas lines, saying the company failed to account for critical pressure sensors as workers replaced century-old cast-iron pipes in Lawrence. That omission caused high-pressure gas to flood the neighborhoods distribution system at excessive levels. Todays resolution with the U.S. Attorneys Office is an important part of addressing the impact.
