| 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. | |
| 5 | |
| 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" | |
