Consider a CPU that implements four parallel fetch-execute pipelines for superscalar processing. Show the performance improvement over scalar pipeline processing and no-pipeline processing, assuming an instruction cycle similar to figure 4.1 in the commentary, i.e.:
and a 60 instruction sequence:
No pipelining would require __?__ clock cycles:
A scalar pipeline would require __?__ clock cycles:
A superscalar pipeline with four parallel units would require __?___ clock cycles:
Assume a multithreaded application uses onlyreader-writer locks for synchronization. Applying the four necessary conditions for deadlock, is deadlock still possibleifmultiple reader-writer locks are used?
A function of n, the number of data items being manipulated. For each expression, determine the dominant term and then classify the algorithm in big-O terms.
Discuss the examples of famous assignments that have failed because of relatively simple errors?
Assume that the passwords were eight characters long but that the salt length was increased to 24 bits. Again, the salts (and the corresponding algorithms) are known to all users. What would be the expected time to find all users' passwords using ..
