Final answer:
b) the sending process sends the message and resumes operation. The correct answer is Non-blocking send allows for the process to continue executing other operations without waiting for the message to be delivered.
Step-by-step explanation:
In the context of non-blocking send operations in message passing for parallel computing, the correct option is: b) the sending process sends the message and resumes operation. In a non-blocking send, the sending process initiates the send operation and then proceeds with its execution without waiting for the message to be received.
This is different from a blocking send, where the sending process would wait until the message has been received by the receiver process before continuing its execution.
In a non-blocking send, the sending process sends the message and resumes operation without waiting for the message to be received. This means that the sending process does not block or wait for a response before continuing its execution. It sends the message and moves on, allowing other tasks to be performed.
This is in contrast to a blocking send, where the sending process waits for the message to be received before resuming its operation.
For example, imagine a chat application where a user sends a message to another user using a non-blocking send. The sending user can continue to type and send more messages without waiting for the recipient to receive and acknowledge the message.
