(The context for this question is the same as the previous question) Modern data-center processors support “core parking” — idle processors are temporarily powered off to save energy, and all threads must be migrated elsewhere. Assume Processor 5 (heavily used by a set of long-running threads) is suddenly parked due to low utilization detected over the last few seconds.  Some time later, Processor 5 is un-parked. Assume T1 and T2 (in that order) are the only two threads that are currently in the run queue awaiting to be scheduled. If the scheduling discipline is LP, which thread will processor 5 pick to run

Assume you are designing a program for a system with thousands of processors. Your program will use only a single mutual exclusion lock. Space overhead is a primary design concern. You decide to use the linked-list-based lock proposed in the MCS paper.  Your classmate argues that the Anderson array-based lock would work equally well for your use case, since your program only ever needs a single lock. Assume you are considering only asymptotic space cost. Is your classmate correct? Explain why or why not.

Who am I? I am very picky, and decide to die in the college lab. I am so picky that I didn’t grow on the expensive Modified Thayer Martin agar. I love glucose and glucose only. Calcium alginate and dacron swabs will kill me. Women often don’t know I am around, but I can silently wreck their fertility. Who am I?
