For achieving the scaled speedup of 512, only about 0.1998% of the program can be executed sequentially. The vast majority of the program must be executed in parallel to achieve such a high speedup.
The scaled speedup S is given by:
S = N / (1 + (N-1)*F)
where N is the number of processors (nodes) and F is the fraction of the program that must be executed sequentially.
We are given S = 512 and N = 1024, and we want to find F.
Substituting the given values, we get:
512 = 1024 / (1 + (1024-1)*F)
Simplifying and solving for F, we get:
F = (1023/1024) / 511
F ≈ 0.001998
Therefore, for achieving the scaled speedup of 512, only about 0.1998% of the program can be executed sequentially. The vast majority of the program must be executed in parallel to achieve such a high speedup.

The value of E[1][2] is 'blue'
How to determine the value of E?The code segment is given as:
A = [21, 'dog', 'red']
B = [35, 'cat', 'blue']
C = [12, 'fish', 'green']
E = [A, B, C]
The above code segment is written in Python, and the lists A, B and C are merged to form list E
This means that list E would be a two-dimensional list.
So, the value of E is [[21, 'dog', 'red'], [35, 'cat', 'blue'], [12, 'fish', 'green']]
Rewrite as:
E = [[21, 'dog', 'red'],
[35, 'cat', 'blue'],

Accessibility is the degree to which a product or service is readily available and usable by _____.

Answer:
A-As many people as possible
A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are: 1) The year must be divisible by 4 2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400 Some example leap years are 1600, 1712, and 2016. Write a program that takes in a year and determines whether that year is a leap year. Ex: If the input is:
1712 the output is: 1712 is a leap year. Ex: If the input is: 1913 the output is: 1913 is not a leap year
Your program must define and call the following function. The function should return true if the input year is a leap year and false otherwise. def is_leap_year(user_year) Note: This is a lab from a previous chapter that now requires the use of a function,
Based on the fact that the program should be able to return true if the input is a leap year, and false if the input is not, the program is shown below.
What program will return true if it is a leap year?In order to make a program that tells whether a year is a leap year or not, you need to start off with the definition:
def is_leap_year(user year):
Then continuing the program, the full code would be:
def is_leap_year(user_year):
if(user_year % 400 == 0):
return True
elif user_year % 100 == 0:
return False
elif user_year%4 == 0:
return True
else:
return False
if __name__ == '__main__':
user_year = int(input())
if is_leap_year(user_year):
print(user_year, "is a leap year.")
else:
print(user_year, "is not a leap year.")
If you input the year, 1712, the program would return the result, "1712 is a leap year."
