Assume a gpu architecture that contains 10 simd processors. each simd instruction is 32 bits, and each simd processor contains 8 lanes for single precision arithmetic, and load/store instructions, meaning that each non-diverged simd instruction can produce 32 results every 4 cycles. assume a kernel that has divergent branches that causes, on average 80% of threads to be active. also assume that 70% of all instructions are sp arithmetic and 20% load/store. because not all memory latencies are covered, assume an average simd instruction issue rate of 0.85. assume the gpu has a clock speed of 1.5 ghz. compute the throughput, in gflop/sec, for this code on this gpu.

Write a modular program (no classes yet, just from what you learned last year), that allows two players to play a game of tic-tac-toe. use a two-dimensional char array with 3 rows and 3 columns as the game board. each element of the array should be initialized with an asterisk (*). the program should display the initial board configuration and then start a loop that does the following: allow player 1 to select a location on the board for an x by entering a row and column number. then redisplay the board with an x replacing the * in the chosen location. if there is no winner yet and the board is not yet full, allow player 2 to select a location on the board for an o by entering a row and column number. then redisplay the board with an o replacing the * in the chosen location. the loop should continue until a player has won or a tie has occurred, then display a message indicating who won, or reporting that a tie occurred. player 1 wins when there are three xs in a row, a column, or a diagonal on the game board. player 2 wins when there are three ox in a row, a column, or a diagonal on the game board. a tie occurs when all of the locations on the board are full, but there is no winner. input validation: only allow legal moves to be entered. the row must be 1, 2, or 3. the column must be 1, 2 3. the (row, column) position entered must currently be empty (i.e., still have an asterisk in it).
