Question

Q2. Determine if the following problems exhibit task or data parallelism: 1. Web server that listens to new connections and serves many connections simultaneously. 2. Search a huge file and count the occurrence of specific word. 3. Change the sharpness of A large image

Answer 1

Task parallelism means where we can do multiple independent tasks more like separate programs each working on their data on the other hand data parallelism means where we divide data and do the same tasks on different processors.

1. A web server that listens to new connections and serves many connections simultaneously.

This case it is task parallelism where the processor has to identify every new connection and also serves the current connections, (two different tasks).

2. Search a huge file and count the occurrence of a specific word.

This case it is task parallelism where the task is to search the file and count the occurrence of a word, (two different tasks).

3. Change the sharpness of a large image.

This case data parallelism because the same task is divided into several threads and process simultaneously, (only one task, parallel processing).
