Editing Consistency model (section)

===Entry consistency ===
This is a variant of the release consistency model. It also requires the use of ''acquire'' and ''release'' instructions to explicitly state an entry or exit to a critical section. However, under entry consistency, every shared variable is assigned a synchronization variable specific to it. This way, only when the acquire is to variable x, all operations related to x need to be completed with respect to that processor. This allows concurrent operations of different critical sections of different shared variables to occur. Concurrency cannot be seen for critical operations on the same shared variable. Such a consistency model will be useful when different matrix elements can be processed at the same time.
