Q4. (a) Consider the following MPI code. Does it compile and run correctly? Correct the code if necessary. Explain what the two functions MPI_Comm_rank and MPI_Comm_size do. #include "mpi.h" #include <stdio.h> int main(int argc, char *argv[]) { int rank, size; MPI_Comm_rank(MPI_COMM_WORLD, &rank ); MPI_Comm_size(MPI_COMM_WORLD, &size); printf( "I am %d of %d\n", rank, size); MPI_Finalize(); return 0; } (b) (5) Explain the difference between blocking and non-blocking communication. Explain clearly the two functions in MPI for blocking communication and the parameters they require. (5)

Table 2 Projected Cash Flow Statements (In Millions) Year 1 Year 2 Year 3 Year 4 Year 5 Sales $20 $53 $102 $117 $129 Cost of goods sold 10 26 51 59 65 Gross margin $10 $27 $51 $58 $ 64 General/administrative expenses 5 10 19 23 25 Debt service requirements 5 5 5 5 10 Pre-tax earnings $0 $12 $27 $ 30 $ 29 Taxes 0 5 12 13 14 Net income $0 $7 $ 15 $ 17 $ 15 Depreciation/amortization 2 6 6 6 6 Terminal value 116 Net cash flow $2 $13 $21 $23 $137 Notes: (a) Depreciation/amortization expense is included in the cost of goods sold, yet it is a noncash charge. Thus, it must be added back to net income to obtain the net cash flow in each year. (b) The terminal value is the present value, as of the end of Year 5, of the equity cash flows that are expected to occur after Year 5. This value was obtained by assuming 10 percent annual growth in equity cash flows after Year 5 and a cost of equity of 30 percent: Terminal value = \frac{$21(1.10)}{0.30 - 0.10} = $116.

Will pay the fixed rate to firm A. The terms of the swap are as follows: 7/1/2011, and 1/1/2012. On each coupon date, A pays to B an amount determined by the 6-month LIBOR rate 6 months in advance. Thus, on 7/1/2011, A would pay to B an amount based upon the actual 6-month LIBOR rate reported on 1/1/2011. On each coupon date, B pays to A a fixed payment based on the rate required to price the fixed leg of the swap at par value on 1/1/2010. Now we jump ahead to January 2, 2012. The actual LIBOR rates for reported in the Table below. Date Maturity in Years 0.5 1.0 1.5 2.0 1/1/2010 2.00 2.25 2.50 2.75 7/1/2010 2.10 2.30 2.70 3.00 1/1/2011 2.40 2.50 2.70 2.60 7/1/2011 2.50 2.50 2.50 2.50 1/1/2012 2.30 2.20 2.15 2.10 a) On date 1/1/2010, what is the amount of the fixed payment that B anticipates paying to A on each coming coupon date? b) On date 1/1/2010, what is the amount of the floating payments that A anticipates paying to B on each coming coupon date? c) Verify that on 1/1/200 the present discounted value of the net coupon payments is zero. d) Assuming that both A and B held this swap to maturity, what were the actual payments that A and B made at each coupon date?
