Suppose you have a machine which executes a program consisting of 60% floating point multiply, 20% floating point divide, and th

e remaining 20% are from other instructions.
(a) [3] Management wants the machine to run 4 times faster. You can make the divide run at most 3 times faster and the multiply run at most 8 times faster. Can you meet management’s goal by making only one improvement, and which one?
(b) [2] Dogbert has now taken over the company removing all the previous managers. If you make both the multiply and divide improvements, what is the speed of the improved machine relative to the original machine?

Answer:

Given that Program instructions consists of:

  • 60% floating point multiply
  • 20% floating point divide
  • 20% other instructions

Amdahl's law states that:

Execution time affected by improvement = (Execution time after improvement/ Amount of improvement) + (Execution time unaffected)

Assuming initially that floating point multiply, divide and other instructions have same clocks per instruction (CPI).

Part (a)

New execution time after improvement with multiply = (60) / 8 + (20 + 20) = 47.5

New execution time after improvement with Divide = (20) / 3 + (60 + 20) = 86.67

New system should be 4x faster which means new execution time should be below = 100/ 4 = 25.

Therefore, Management's goal can NOT be achieved by making the improvement with multiply or divide alone.

Part (b)

New execution time after improvement with multiply and divide = (60 / 8) + (20 / 3) + 20 = 34.17

Speed up = execution time of original machine / Execution time of new machine = (100 / 34.17) = 2.93

Therefore, new machine is 2.93 times faster than original machine.

As an offer, this is effective.
Ogden obviously wants to know something about Shakespearean comedy, because he may need it for an exam, or his job, or maybe he is just interested in the subject. Thus, he wishes to learn this from someone, which makes Naomi's offer an effective one.

A one-month European call option on a non-dividend-paying stock is currently selling for $1. The stock price is $47, the strike
REY [17]

Answer:

The price of the put-option on the same stock with the same strike price is $3.75.

Explanation:

To find the price of the put option on an underlying asset given the price on the call option's price for the same underlying asset with the same strike price is given, we apply put-call parity model.

Put call parity model: p = K x e^(-rT) + c - St .

in which: p: put option's price;

               K: underlying asset's strike price;

               r: risk-free rate;

              T: time to maturity denominated in year;

               c= call option's price;

              St = spot price of underlying asset .

So, p = 50 x e^(-0.06 x 1/12) + 1 - 47 = $3.75 .

Find an example of a company's aggregate planning strategy. You can use the strategy from the firm where you currently work or w
galina1969 [7]

Explanation:

An aggregate planning strategy can be defined as the implementation of new strategic action plans used in a company whose objective is to balance supply and demand through the implementation of material resources, sales, promotions, products, etc.

This planning occurs in the short term, and is usually carried out when a company has the capacity to meet a certain market offer, such as consumer demand for an innovative product.

Aggregated planning is a good strategy when the company considers maximizing its profits, so in order to achieve the expected result, market demand must be thoroughly analyzed, the company's operational capacity, risks, budget and other essential variables.

A soft drink factory for example can carry out a promotional campaign in the style buy 1 light 2 to increase its demand, therefore you must be aware that your productive force will be able to meet the demand, in addition to analyzing the strategic results in order to ascertain the effectiveness planning.

Russnak Corporation is investigating automating a process by purchasing a new machine for $505,000 that would have a 10 year use
Svetradugi [14.3K]

Answer:

20.1%

Explanation:

The computation of the simple rate of return is shown below;

= (operating cost - depreciation) ÷ (purchase of new machine - scrap value)

= ($145,500  - $50,500) ÷ ($505,000 - $35,000)

= ($94,500) ÷ ($470,000)

= 20.1%

hence, the simple rate of return is 20.1%

The same would be considered and relevant
