Failures_and_Recovery_3b RioVista   The context for this question is the same as the previous question. 3. Consider RioVista, which implements LRVM semantics on top of Rio file cache.   (b) Does the implementation use UNDO log or UNDO record? Why? What is the difference between the two?

Real_time_and_Multimedia_1a TS-Linux   1. Assume that you are playing a game (G) on a version of TS-Linux in which the scheduler strictly follows the born priority of all the processes in making its scheduling decisions. The game uses ONE-SHOT timer with an overshoot parameter of To. The timer event goes off at time 0. Assume the following: When the timer goes off, the kernel has just started a critical section of duration Tk. For taking the necessary gaming action for the timer event, the video game application (G) has a processing time of Tg and priority P1. In addition to Tg, the application will need to make a blocking call to a Window Manager process (W) has a processing time of Tw and priority P3. When the timer goes off, the scheduling queue is empty. The priorities are ordered as P1 > P2 > P3 > P4 > …. With P1 being the highest priority. There are no periodic timers in the system. Duration of the scheduling time and interrupt handing time are negligible. Note that the given image is simply for your reference, and that the time Th has nothing to do with the solution. Only use the variables given in the text in your solutions.   (a) What is the maximum latency from time 0 for G to complete the action in response to the timer interrupt? Show your work.

Failures_and_Recovery_3c RioVista   The context for this question is the same as the previous question. 3. Consider RioVista, which implements LRVM semantics on top of Rio file cache.   (c)  Compare the log truncation code of RioVista to that of Satya’s LRVM.
