- * Test logic:
- * For each of the two parrot neurons, exactly one connection from/to the
- * in/out MUSIC proxy must be created, specifically to the proxy on the
- * rank on which the parrot neuron exists. Therefore, the pooled connections
- * across ranks must be identical independent of number of ranks.
