A program must execute 10¹² instructions to solve a problem. A single processor system can solve the problem in 10⁶ seconds. Thus on average the single processor system executes 10⁶ or 1-million instructions per second.

We have a new program that has been parallelized for execution on a distributed-memory system. This parallel program uses (p) processors. Here each processor will execute 10¹²/p instructions and each processor must send 10⁹(p-1) messages. We will assume there is not additional overhead for the parallel program and that the program will complete after each processor has executed all of its instructions and sent all of its messages (there are no delays for things like waiting for messages).

2.a. If it takes 10^-3 seconds to send a message, how long will it take the program to run with 1000 processors if each processor is as fast as the single processor where the serial program was run?

2.b. If we upgrade our network and it now takes only 10^-9 seconds to send a message. Same question – how long to run on the same 1000 processors now?

The speed at which a processor can process instructions can be increased by making its clock speed higher, or by increasing the amount of L1 cache memory on the processor chip. Explain the terms clock speed and L1 cache and briefly discuss how increasing each of them increases the speed at which instructions can be processed. The maximum word limit for Question 3(a) is 150 words. b.You have the choice of buying two processors: Processor 1 has a clock speed...

(Use the string class to solve the problem) Write a program (in c++) that can be used to train the user to use less sexist language by suggesting alternative versions of sentences given by the user. The program will ask for a sentence, read the sentence into a string variable, and replace all occurrences of masculine pronouns with gender-neutral pronouns. For example, it will replace “he” with “she or he”, and “him” with “her or him”. Be sure to preserve...

Design and Requirements In order to execute its task the program must compare character values. For instance, a character named symbol is an upper case letter if and only if the boolean expressions ‘A’ <= symbol and symbol <= ‘Z’ both evaluate true. Analogous expressions can be used to check for lower case letters between ‘a’ and ‘z’ and for digits between ‘0’ and ‘9’. To see if symbol is the ‘$’ or ‘_’ character, the relational operator == shall...
