Briefly describe the issue of branch divergence in graphical processing units. How can we ensure that the program function correctly when branch divergence occurs? In addition, list any potential negative effects of branch divergence. 

 

Branch divergent is a crucial issue that causes the degrading of the performance of General Purpose Graphics Processing unit.

We can ensure that the program functions correctly when branch divergence occur by eliminating the branch divergence : enable all the threads to execute all of its codes.

Branch divergence messes up with algorithms in the program so if it occurs, you need to restructure the algorithms into a higher level, and it can be a hassle for most people.
