Distributed Shаred Memоry The cоntext fоr this question is the sаme аs the previous question. [8 points] In Treadmarks DSM system the following critical section is executed at a node N1: Lock(L1); // Assume X is the only page that been modified up to this point by prior acquirers of L1 Write to Page X; // Assume that the page is not present at this node; // Assume that there are three diff files for page X // named Xd2, Xd3, and Xd4 in nodes N2, N3, and N4 // respectively. // Assume the sync causality for the lock L1 is // N3 -> N2 -> N1 (i.e, this is the order of lock // acquisition).Unlock (L1); b) [2 points] What additional actions would be carried out by Treadmarks at Node 1 before the critical section is executed by N1?
