2 This test app is for VReo development.. first version replicates a program

3 from the paper. It has two producers and one consumer. The circuit causes

4 the producers to take turns providing the next input that the consumer takes.

6 The circuit is in the paper..

7

8 The way the code works, the circuit is supplied separately. A function is

9 generated by a tool, which creates the circuit data structs. Those structs

10 contain pointers to the functions that check transitions and then perform

11 transitions.

12

13 So, the seed first starts up VReo, then it calls the create circuit Fn,

14 which returns a pointer to the circuit, then it calls create_VP three

15 times. The first, it hands it the pointer to the producer Fn, along with

16 a pointer to the circuit and an integer that indicates that it connects to

17 port 1 of the circuit. Second, it creates another producer, but connected

18 to port 2, then it creates a consumer connected to port 3.

19

20 Then, it waits for the computation to end.

21

22 A producer puts out 5 items, doing a print for each. The consumer consumes

23 10 items, doing a print for each.

24

25 Then each of them call "end_VP".

26

27 That ends the computation, and the seed comes back, and calls "end_seed_VP"
