Potpourri_5 Potpourri 5. [4 points] In a shared memory system with 8 processors, the processors reach a common barrier in the following order: P5, P4, P7, P1, P0, P6, P2, P3 The underlying implementation of the barrier is a sense-reversing tree which appears as follows: For each of the nodes N0 to N6 in the tree, indicate both –  [+2 points] the processor which spins on the sense variable,  [+2 points] the processor which flips it.
