In contrast, software prefetching can determine nonunit strides as easily as it can determine unit strides. Assume prefetches write directly into the cache and that there is no ``pollution'' (overwriting data that must be used before the data that are prefetched). For best performance given a nonunit stride prefetcher, in the steady state of the inner loop, how many prefetches must be outstanding at a given time?

answer; code of ethicsi believe is the correct answer;

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.
