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

B

C

D

% resources needed

41

% parallelizable

50

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.

lord [1]

Answer:

Here you go, alter this as you see fit :)

Explanation:

array = []

cnt = 0

while cnt < 11:

x = input("Enter a word: ")

array.append(x)

cnt += 1

y = input("Add another word?(Y/n): ")

if y.lower() == "n":

break

letter = input("\nChoose a letter: ")

if len(letter) != 1:

print("Error: too many characters")

quit()

for n in range(len(array)):

if letter.lower() in array[n].lower():

print(array[n], end= ",")

Compute the approximate acceleration of gravity for an object above the earth's surface, assigning accel_gravity with the result

Zepler [3.9K]

Answer:

The summary of the given query would be summarized throughout the below segment. The output of the question is attached below.

Explanation:

Given values are:

$G = 6.673e-11$
$M = 5.98e24$
$accel \ gravity = 0$
$dist\ center=float(inp())$

here,

inp = input

By utilizing the below formula, we get

⇒ $\frac{GM}{d^2}$

Now,

⇒ $accel \ gravity=\frac{G\times M}{dist \ center**2}$

⇒ print("Acceleration of gravity: {:.2f}".format(accel_gravity))
