This question is incomplete. The complete question is given below:
Your company has just brought a new 22-core processor, and you have been tasked with optimizing your software for this processor. You will run four applications on this system, but the resource requirements are not equal. Assume the system and application characteristics listed in table 1.1
Table 1.1 Four Applications
Application
A
B
C
D
% resources needed
41
27
18
14
% parallelizable
50
80
60
90
The percentage of resources of assuming they are all run in serial. Assume that when you parallelize a portion of the program by X, the speedup for that portion is X.
a. How much speedup would result from running application A on the entire 22-core processor, as compared to running it serially?
Answer:
Speedup = 50
Explanation:
- The speedup for that portion is x if we parallelize a portion of that program by X.
- If the whole program has no parallelize portion or in other words the whole program is running serially then the speedup will be zero.
- So in this scenario if parallelizable portion of A is 50% so according to above description the speedup is 50.
Answer: Dereferencing a variable that is not a pointer
Explanation:
The execution time also refered to as the CPU time pertaining to a given task is the time that is used by the system to execute a task.
Some of the reasons for a fatal execution-time error include:
• Dereferencing a pointer that has not been initialized properly
• Dereferencing a null pointer
• Dereferencing a pointer that has not been assigned to point to a specific address.
It should be noted that dereferencing a variable that is not a pointer doesn't cause a fatal execution-time error.
Answer:
Like when your doing an application for a job or anything important lol
Explanation:
Answer:
import csv
def Csvreader(filename):
with open("filename", "r") as file:
content = file.csv_reader()
list_content = list(content)
file.close
return list_content
Explanation:
This is a python description of the function that reads the csv file and converts it to a list, from the list, each item can accessed with its index and updated directly. Use this to draw the same conclusion for a java program.
