Which of the following is true about scalability?

i. weak scaling is easier to achieve than strong scaling due to amdahl’s law.

ii. amount of communication among processors usually remains constant or grows slowly.

iii. weak scaling is defined as how the execution time varies with number of processors for fixed problem size per processor.

iv. data dependencies increase with larger problem sizes.

Option (i) is the correct answer to the following question.

Explanation:

Because to achieve the strong scaling then, we have required the Amdahl’s law and the scalability is the weak scaling that is easier to instate than the powerful scaling scalability because of only Amdahl’s law.

So, that's why the following option is correct.

Option (ii) is incorrect because usually, there no communication among the procedures.

Option (iii) is incorrect because the following option is not related to the following statement.

Option (iv) is incorrect because the dependency of the data or information is decreased.

we can all learn from our past mistakes because we all have different ways of learning different types of techniques. my way may or may not another classmate remember and have the repetition to acknowledge such standard. such as remembering acronyms. using abbreviations to us remember keep things in order in our memory. this us figure out what comes next in the sequence. if so, what we have is a sentence of just letters all in caps. we either know the meaning or have no idea what it stands for. most of the time we know the meaning and context. but most of us who don't know, should learn by having a quick glance at what needs to be remembered. such as repetition in the memory for acronyms. one way that me, is the fact that i'm always doing math and english assignments. so we have to remember specific meanings such as soapstone for documents, such as citing correctly. or pemdas for doing the equations correctly, even if it's the super long way. this works for everyone. you just have to find what works for you by practicing and repetition daily.
