Question
5. First, write down a list of your daily activities that you typically do on a
weekday. For instance, get out of bed, take a shower, get dressed, eat breakfast
etc. Make sure to break down your list so you have a minimum of 15 activities.
a) Now consider which of these activities is already exploiting some form of
parallelism (for instance, carrying one book at a time to school, versus
loading them all into your backpack and then carry them “in parallel”). For
each of your activities, discuss if they are already working in parallel, but if
not, why they are not.
b) Next, consider which of the activities could be carried out concurrently
(e.g., eating breakfast and listening to the news). For each of your activities,
describe which other activity could be paired with this activity.
c) For (b), what could we change about current systems so that we could
perform more tasks in parallel?
d) Estimate how much shorter time it would take to carry out these activities
if you tried to carry out as many tasks in parallel as possible.
Explanation / Answer
Solution:
The activities are:
a)
In above-mentioned activities, some activities are exploiting some form of parallelism
like the revision of chapter can be done parallelly with the breakfast of brushing teeth.
Each of the activities cannot be performed in parallel since you cannot meditate while taking shower or having a breakfast.
They are not in a parallel manner because it is not possible to paralyze them.
b)
Brushing the teeth can be paired with preparing backpack or the revision of the chapter
or breakfast can be done with watching the news or preparing backpack.
d)
We can club or pair together the processes which can be performed in parallel
d)
Suppose every activity is taking one unit of time from the 14 given above
after parallelism, they can be performed in
10 unit of time.
