For simplicity, assume that the second operation begins after the first completes, even though they are on different processor cores.
for implementation 1,
* the first read generates 50 stall cycles because the read is satisfied by c0’s cache: c1 stalls for 40 cycles while it waits for the block, and c0 stalls for 10 cycles while it writes the block back to memory in response to c1’s request; and
* the second read by c3 generates 100 stall cycles because its miss is satisfied by memory.
therefore, this sequence generates a total of 150 stall cycles.
for the following sequences of operations, how many stall cycles are generated by each implementation?
a) c0: r, ac20
c0: r, ac28
c0: r, ac30
b) c0: r, a00
c0: w, ac08 < - 48
c0: w, ac30 < - 78

Read the excerpt below from the poem "exile" by julia alvarez and answer the question that follows. i let myself lie back in deep waters, my arms out like jesus' on his cross, and instead of sinking down like i'd always done, magically, that night, i could stay up, floating out past the driveway, past the gates, in the black ford, papi grim at the wheel, winding through the back roads, stroke by difficult stroke, out on the highway, heading toward the coast. which literary device is used in the comparison between the speaker's experience of fleeing the country and floating in the ocean? i let myself lie back in deep waters, my arms out like jesus' on his cross, and instead of sinking down like i'd always done, magically, that night, i could stay up, extended metaphor symbolism simile theme
