Hi everybody,
Does anyone know that which machine (or what kind of architecture)
can efficiently execute the following codes with barrier synchronizations.
(For example, machines with VLIW architecture, or others?)
DoAll 200 I=1,N
DoSequential 100 J=1,M
loop body;
100 Continue
Barrier;
200 Continue
That is, the scenario of execution may look like:
* * * * * * * * * * * * * * * * * * * * (start)
