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.

an object travels 16 metre in 4 seconds and then another 16 metre in 2second what is the average speed of the object
Zigmanuir [339]

Answer:

6m/s

Explanation:

Given the information :

an object travels 16 metre in 4 seconds and then another 16 metre in 2second.

what is the average speed of the object?

First portion of travel:

Distance = 16 meters

Time = 4 seconds

Second portion:

Distance = 16 meters

Time = 2 seconds

Speed is calculated as the proportion of distance traveled to the time taken.

Speed = distance / time

First portion :

Speed attained

Distance / time = speed

16 meters / 4 seconds = 4m/s

Second portion:

Speed attained

Distance / time = speed

16 meters / 2 seconds = 8m/s

Average speed :

(first portion + second portion) / 2

(4m/s + 8m/s) / 2

12m/s ÷ 2

= 6m/s

Fresher Foods, Inc., orally agreed to purchase one thousand bushels of corn for $1.25 per bushel from Dale Vernon, a farmer. Fre
Yuri [45]

Answer:

In the case of Fresher Goods, Inc.v. Vernon, the trial court will possibly conclude that Vernon must complete the portion of the payment which has already been compensated for as a result of partial results.

Explanation:

Vernon accepted partial payment for the sold goods. While the Law of Frauds demanded that any contract for the selling of goods at a price of $500 or more be enforceable in writing, the oral arrangement was partially compensated and agreed by all parties. That part of the deal was binding, so Vernon would supply 100 corn bushels to Fresher for $1.25 per bushel.

Sergio039 [100]

Answer:

Explanation:

Calculation to determine How much, expenses can the Spencers deduct

Airfare (one ticket) $1,300

(2,600/2)

Lodging $675

Meals $555 [($1,110/2)]

Less: 50% limit $278

$277 [$555-$278]

Registration fee ($580 − $120) $460

Car rental $305

Total $3,017

($1,300+$675+$277+$450+$305)

Therefore the expenses that Spencers can deduct will be $3,017

Explanation:

Giving the following information:

Materials inventory, January 1 - $33,660

Materials purchases - $148,800

Material transportation-in - $600.

The material transportation is part of the cost of materials. We need to use the following formula:

Direct materials for use= beginning inventory + purchases

Direct materials for use= 33,660 + (148,800 + 600)

Direct materials for use= $183,060
