6. [Implementation Testing] (15 points) You are to implement and test a program for summing 1/x as x runs over all approximately eight million (23 fraction bits) single precision floating point numbers in the interval [1, 2). You are to do this on a server, PC (or Mac) of your choice. You are first asked to predetermine estimates of your implementation's computation time (architecture and compiler dependant), result accuracy (algorithm and round-off dependant), and result value (real valued sum estimate). Specifically: a. Discuss the computational environment for your tests, including the compiler, operating system, machine MHz and cycle times for appropriate instructions and whether pipelining affects your execution time. b. Predetermine an estimate of the time utilizing single precision for the variables for all computations from any documentation you can find from the hardware manufacturer and/or compiler and system provider. c. Predetermine a rough estimate of the exact sum (hint: how many terms are being added and how large is an "average term"). d. Predetermine an estimate of the accuracy. Single precision computation should be done in round to nearest mode as provided by standard C implementations. By accuracy of the sum we mean the difference between the rounded sum of rounded values compared to the exact sum of exact values. e. Give the measured running time and the computed result for your implementation. Compare the results with your estimates of running time and approximate sum. Compute the sum in double precision and single precision and compare to give a reasonable value for the accuracy of the single precision sum. Compare your result with another student's results that might have performed the sum in a different order. Can you explain the size of the approximation error?
Discuss how expert systems, neural networks, and genetic algorithms can help scientists meet medical challenges. Provide an example of each system.
Your company is trying to decide whether to execute intrusion detection system (IDS), or intrusion prevention system (IPS).
Now try and see what happens if this variable is declared as a JSP scriptlet. c.Also display the name of the server as well as any cookie information that you can find.
One option used to speed up disk drives is to add a cache that hold either recently accessed blocks, blocks waiting to be written to the disk, or that is used to "prefetch" blocks for a file. If the disk speed is approximately 3ms for a block and the..
What is the main advantage of using master pages. Explain the purpose and advantage of using styles.
Transform the query into a query on fragments.
what is the effect of the following statements?
C sharp Write C# code to prompt a user to enter the number of miles he or she has driven and the gallons of gas used
Hint: use the logical operators to combine the 3 pins into one number, then divide that number by 8 (23) to find the fraction of the conversion and multiply that by 5V which would be the Arduino operating voltage.
If the government imposes the same below-equilibrium price ceiling on all these markets, which of the following statements will be true?
Few organizations tend to prefer operating expense models. whether Cloud providers will continue to secure large amount of capital....or will equity firms stop their funding?
