| seanhalle@0 | 2 This test app is for VReo development.. first version replicates a program |
| seanhalle@0 | 3 from the paper. It has two producers and one consumer. The circuit causes |
| seanhalle@0 | 4 the producers to take turns providing the next input that the consumer takes. |
| seanhalle@0 | 5 |
| seanhalle@0 | 6 The circuit is in the paper.. |
| seanhalle@0 | 7 |
| seanhalle@0 | 8 The way the code works, the circuit is supplied separately. A function is |
| seanhalle@0 | 9 generated by a tool, which creates the circuit data structs. Those structs |
| seanhalle@0 | 10 contain pointers to the functions that check transitions and then perform |
| seanhalle@0 | 11 transitions. |
| seanhalle@0 | 12 |
| seanhalle@0 | 13 So, the seed first starts up VReo, then it calls the create circuit Fn, |
| seanhalle@0 | 14 which returns a pointer to the circuit, then it calls create_VP three |
| seanhalle@0 | 15 times. The first, it hands it the pointer to the producer Fn, along with |
| seanhalle@0 | 16 a pointer to the circuit and an integer that indicates that it connects to |
| seanhalle@0 | 17 port 1 of the circuit. Second, it creates another producer, but connected |
| seanhalle@0 | 18 to port 2, then it creates a consumer connected to port 3. |
| seanhalle@0 | 19 |
| seanhalle@0 | 20 Then, it waits for the computation to end. |
| seanhalle@0 | 21 |
| seanhalle@0 | 22 A producer puts out 5 items, doing a print for each. The consumer consumes |
| seanhalle@0 | 23 10 items, doing a print for each. |
| seanhalle@0 | 24 |
| seanhalle@0 | 25 Then each of them call "end_VP". |
| seanhalle@0 | 26 |
| seanhalle@0 | 27 That ends the computation, and the seed comes back, and calls "end_seed_VP" |
