Consider the two matrix multiplication schemes in Example 3.23 of the book. Assuming a fixed efficiency of E = 0.25, system B is more scalable than system A by the isoefficiency metric, for all values of b, c >0. Assuming b = 4c, we have W(A) = 1.33^3 n^1.5 and W(B) = ^ 1.5. How much more scalable is B over A under the above conditions? See the parallel execution times in Table 3.25. Derive an expression for the ratio Tn(B) /Tn(A), when. Can system B be slower than system A? Explain why or why not.

Write a program that starts off with a list of types of currency in the program (see bottom for data that i to be preloaded upon start). The program should display a menu and not exit the program/menu until th user decides to exit. The menu should be able to do all of the following nine functions: 1) Display to the user of the various currency types that exist in the list (table/column format) a. Must use a loop through method to display b. Must have a banner or header 2) Indicate to the user how many currency types are in the currency list a. Must be displayed in a sentence format 3) Indicate to the user if the type of currency queried exists or not in the currency type list a. Must be displayed in a sentence format 4) Return the index number (list position) of a queried currency type a. Must be displayed in a sentence format b. Must inform the user if the currency type is not found in the list in a sentence format 5) The program must be able add a currency type to the list of currency types a. Confirm to the user that the currency type was added in a sentence i. Followed by displaying the updated list

Write a procedure that produces N values in the Fibonacci number series and stores them in an array of doubleword then display the array to present Fibonacci numbers in hexadecimal (calling the DumpMem method from the Irvine32 library). Input parameters should be a pointer to an array of doubleword, a counter of the number of values to generate. Write a test program that calls your procedure, passing N = 30. The first value in the array will be 1, and the last value will be 832040 (000CB228 h)

Water at = 0.02 kg/s and T-20C enters an annular region formed by an inner tube of diameter D,- 25 mm and an outer tube of diameter D-100 mm. Saturated steam flows through the inner tube, maintaining its sur- face at a uniform temperature of T, = 100C. while the outer surface of the outer tube is well insulated. If fully developed conditions may be assumed throughout the annulus, how long must the system be to provide an out- let water temperature of 75C? What is the heat flux from the inner tube at the outlet?
