Data must be exchanged with other workers;
- Cooperative — all parties agree to transfer data.
- Message-passing is an approach that makes the exchange of data cooperative.
- Data must both be explicitly sent and received.

- One sided — one worker performs transfer of data.
- One-sided operations between parallel processes include remote memory reads and writes.
- An advantage is that data can be accessed without waiting for another process.
