A: Both multithreading and multicore rely on parallelism to get more efficiency from a chip.
B: In coarse-grained multithreading, switching between threads only happens after significant events such as last-level cache miss.
C: In fine-grained multithreading, switching between threads happens after every instruction.
D: Simultaneous multithreading (SMT) uses threads to improve resource utilization of statically scheduled processor.
1d. In the roofline model, the attainable GFLOPs/sec is set by _____?
A: Peak Memory BW x Arithmetic Intensity
B: Peak Floating-Point Performance
C: Min (Peak Memory BW x Arithmetic Intensity, Peak Floating-Point Performance)
D: Max (Peak Memory BW x Arithmetic Intensity, Peak Floating-Point Performance)
Answers
The correct answer is D: Max (Peak Memory BW x Arithmetic Intensity, Peak Floating-Point Performance).
1a. C: 101 to calculate the speedup, we need to consider the computing load distribution among the processors. In this case, 10 processors carry 20% of the load, which means each of these processors handles 2% of the load. The remaining 90 processors share the rest of the load evenly, so each processor among these 90 handles (100% - 20%) / 90 = 0.8889% of the load.
The speedup can be calculated using Amdahl's Law, which states that the speedup is limited by the portion of the program that cannot be parallelized. In this case, the matrix subtraction is fully parallelizable, so the only portion that cannot be parallelized is the sum of the scalar variables.
The speedup formula is given by: Speedup = 1 / [(1 - p) + (p / n)], where p is the portion that can be parallelized and n is the number of processors.
In this case, p = 0.02 (for the 10 processors) and n = 100. Substituting these values into the formula, we get: Speedup = 1 / [(1 - 0.02) + (0.02 / 100)] = 1 / 0.99 = 1.0101.
Therefore, the correct answer is C: 101.
1b. A:
mul.d $v1, $v0, $f1
add.d $v3, $v1, $v2
The code snippet performs the DAXPY operation, which multiplies a scalar value (a) with a vector (x) and adds the result to another vector (y). The blank instructions should be filled with the above choices.
1c. C: In fine-grained multithreading, switching between threads happens after every instruction.
In fine-grained multithreading, switching between threads happens after every instruction, which is an incorrect statement. Fine-grained multithreading allows switching between threads at a much finer granularity, such as cycle-by-cycle or instruction-by-instruction, to improve resource utilization.
1d. B: Peak Floating-Point Performance
In the roofline model, the attainable GFLOPs/sec is set by the peak floating-point performance of the processor. The roofline model is a performance model that visualizes the performance limitations of a system based on the memory bandwidth and arithmetic intensity of the code. The attainable performance is determined by the lower value between the peak memory bandwidth and the peak floating-point performance. Therefore, the correct answer is B: Peak Floating-Point Performance.

what annual medical costs will ronald pay using the sample medical expenses provided if he enrolls in the blue cross/blue shield plan?
Answers
Annual Medical cost = 1269.86
monthly premium cost to Ronald for the Blue Shield plan = $48.48.
For all doctor office visits, prescriptions, and major medical charges, Ronald will be responsible for 35 percent and the insurance company will cover 65 percent of covered charges.
The annual deductible cost = $630.
Ronald decided to review his medical bills from the previous year to see what costs he had incurred and to help him evaluate his choices. He visited his general physician 6 times during the year at a cost = $105 for each visit.
He also spent $71 and $95 on two prescriptions during the year.
= (Monthly premium cost × 12) + Deductible cost + (Coinsurance percent × Coinsurance expenses)
= (48.48 x 12) + 630 + (0.35 x 166)
= 1269.86

Answers
The probability that a randomly selected home in Queens has 4 or more computers is 0.1 or 10%. The correct answer is (b) 0.10.
The given probability distribution table shows the probabilities of having 1, 2, or 3 computers in a randomly selected home in Queens. However, the probability of having 4 or more computers is not given in the table.
To find the probability of having 4 or more computers in a randomly selected home, we can use the complement rule. The complement rule states that the probability of an event happening is equal to 1 minus the probability of the event not happening. In this case, the event we are interested in is having 4 or more computers in a home, and the complement of this event is having 1, 2, or 3 computers in a home.
So, the probability of having 4 or more computers in a randomly selected home in Queens can be calculated as:
P(4 or more) = 1 - P(1 or 2 or 3)
P(1 or 2 or 3) = P(1) + P(2) + P(3) = 0.4 + 0.3 + 0.2 = 0.9
P(4 or more) = 1 - 0.9 = 0.1
Therefore, the probability that a randomly selected home in Queens has 4 or more computers is 0.1 or 10%. The correct answer is (b) 0.10.

The corner Deli operates on an overhead percent of 20% of the selling price, which results on an overhead of $1.25 on the company's private-labeled bags of corn chips. If the corner Deli has a markup of $4.35 on the bag of corn chips, find (a) selling price, (b) net profit, and (c) cost.
Answers
a) The Selling price at a markup of $4.35 on the bag of corn chips is $6.25 b) The Net profit a markup of $4.35 on the bag of corn chips is $3.10 c) The cost at a markup of $4.35 on the bag of corn chips is $1.90.
How to find selling price,net profit, and cost.We can use the following equations to solve for the selling price, net profit, and cost of the corn chips:
(a) Selling price = cost + markup
(b) Net profit = selling price - cost - overhead
(c) Overhead = overhead percent x selling price
Given that the overhead is $1.25 and the overhead percent is 20%, we can calculate the selling price as follows:
Now that we know the selling price, we can use equation (a) to calculate the cost:
(a) Selling price = cost + markup
$6.25 = cost + $4.35
Cost = $6.25 - $4.35
Cost = $1.90
(b) Net profit = selling price - cost - overhead
Net profit = $6.25 - $1.90 - $1.25
Net profit = $3.10
(c) Overhead = overhead percent x selling price
$1.25 = 0.2 x selling price
Selling price = $1.25 / 0.2
Selling price = $6.25
Therefore, the selling price of the corn chips is $6.25, the net profit per bag is $3.10, and the cost is $1.90.

Given the equation f(x)=2x^2-14x+10, find g(x), the image of f(x) after a ry=x (reflection over the line y=x). Express your answer as a single fraction.
Answers
Given:
The function is:
\(f(x)=2x^2-14x+10\)
The function g(x), the image of f(x) after a \(r_{y=x}\) (reflection over the line y=x).
To find:
The function g(x).
Solution:
We have,
\(f(x)=2x^2-14x+10\)
Substitute \(f(x)=y\) in the given function.
\(y=2x^2-14x+10\)
The function g(x), the image of f(x) after a \(r_{y=x}\) (reflection over the line y=x). So, interchange x and y.
\(x=2y^2-14y+10\)
Now, we need to find the value of y.
\(x=2(y^2-7y+5)\)
\(\dfrac{x}{2}=y^2-7y+5\) [Divide both sides by 2]
\(\dfrac{x}{2}-5=y^2-7y\) [Subtract 5 from both sides]
Add both sides half of square of coefficient of y, i.e. \((\dfrac{-7}{2})^2\), to make it perfect square.
\(\dfrac{x}{2}-5+(\dfrac{-7}{2})^2=y^2-7y+(\dfrac{-7}{2})^2\)
\(\dfrac{x}{2}-5+\dfrac{49}{4}=y^2-7y+(\dfrac{7}{2})^2\)
\(\dfrac{x}{2}-5+\dfrac{49}{4}=\left(y-\dfrac{7}{2}\right)^2\) \([\because (a-b)^2=a^2-2ab+b^2]\)
\(\dfrac{x}{2}+\dfrac{49-20}{4}=\left(y-\dfrac{7}{2}\right)^2\)
Taking square root on both sides, we get
\(\pm\sqrt{\dfrac{x}{2}+\dfrac{29}{4}}=y-\dfrac{7}{2}\)
\(\dfrac{7}{2}\pm\sqrt{\dfrac{2x+29}{4}}=y\)
\(\dfrac{7}{2}\pm\dfrac{\sqrt{2x+29}}{2}=y\)
\(\dfrac{7\pm \sqrt{2x+29}}{2}=y\)
Substituting \(y=g(x)\), we get
\(\dfrac{7\pm \sqrt{2x+29}}{2}=g(x)\)
Therefore, the required function is \(g(x)=\dfrac{7\pm \sqrt{2x+29}}{2}\).

The sides of an isosceles triangle are whole numbers, and its perimeter is 30 units. What is the probability that the triangle is equilateral?
Answers
The probability that the triangle is equilateral is `0`.
Let's assume that the two sides of an isosceles triangle are `a`. Then, the perimeter of the triangle is `2a + b = 30`, where `b` represents the base of the triangle.
Substituting the value of `b` in terms of `a` in the above equation, we get:`2a + 2sqrt(a^2 - (30 - 2a)^2/4) = 30`
Simplifying this equation, we get: 4a² - 120a + 675 = 4√(3)a²
Squaring both sides of the equation, we get: 16a⁴ - 960a³ + 40500a² - 243000a + 455625 = 0
The solutions of this equation are: a = 7, 15
The probability of the triangle being equilateral is 0.
An isosceles triangle can be equilateral only if its sides are of equal length. Since there is only one value of `a` such that `2a < 30` and `a` is a whole number, the probability of the triangle being equilateral is 0.
Hence, the probability that the triangle is equilateral is `0`. The given isosceles triangle can have sides of length `7-7-16` or `15-15-0`.
