Now the program will take 6 seconds , before the program use to take 60 second ie 1 min for execution and now the speed of the program is increased to 10 so now it will 10 time faster, so it will take 6 second to execute now..

Suppose that a program obeys Amdahl's law with a sequential fraction of 12%, and that the execution time with one processor is 72 sec. (i.c. T(1) = 72). Calculate the speedups and efficiencies for P = 4, 8. and 12. What is the asymptotic (P rightarrow infinity) speedup and efficiency?

A program executes 10 billion instructions. It executes on an Intel processor that has an average CPI of 1.5 and a clock frequency of 2 GHz. How many seconds does the program take to execute? What is the cycle time of this Intel processor? Assume that an AMD processor takes 6 seconds to execute the program. What is the speedup provided by the Intel processor, relative to the AMD processor

a) Suppose that computer A executes 1 billion instructions per second, and computer B executes 10 million instructions per second, i.e, Computer A is 100 times faster than computer B in raw computing power. Suppose an expert programmer implements insertion sort in machine language for computer A, and the resulting code requires 2 * n2 instructions to sort n numbers. Suppose an average programmer implements merge sort, using a high-level language on computer B, with the resulting code taking 5...

You must justify with calculations each of the following questions: System A has 2 processors, program X takes 10 sec. to execute, in one of the processors. Program Y takes 10 sec. in parallel running to the other processor. System B has only one processor that can run only one program at a time. Program X takes 6 seconds to run on this processor. Program Y takes 6 seconds to run on that processor. Which system would you choose if...

SUBJECT: Computer Architecture, Pipelining PROBLEM: Sequential Process for an annual dental appointment Sequential Process: 1. Check-in patient (1 minute) 2. Take patient to chair and room (1 minute) 3. Complete cleaning (20 minutes) 4. Complete dental appointment (10 minutes) 5. Take patient to check-out counter (1 minute) 6. Check-out patient (1 minute) For sequential process, one person completing each step for 10 patients would take (1 + 1 + 20 + 10 + 1 + 1) * 10 = 340...

You're in charge of running a scientific program (job) that simulates a physical system for as many discrete steps as you can. The lab you're working in has two large supercomputers, which we'll call A and B, which are capable of processing this job. However, you're not one of the high-priority users of these supercomputers, so at any given point in time, you're only able to use as many spare cycles as these machines have available. Here's the problem you...
