>From the standard: A doacross loop nest is a loop nest that has cross-iteration
dependence. An iteration is dependent on one or more lexicographically earlier
iterations. The ordered clause parameter on a loop directive identifies the
loop(s) associated with the doacross loop nest.
This first implementation uses a simple linear tasks distribution
algorithm. Tree-like algorithms can be added later for better
This needs to be put into the OpenMP runtime library in order for the compiler
team to develop the compiler side of the implementation.
