Question 1: What is the difference between Uniform Memory Access (UMA) and Nonuniform Memory Access (NUMA)

Question 2: Consider some parallel program with a percentage of serial work of 40% and serial time 60ms. Calculate the speedup using Amdahls law speedup and efficiency when running program using 1, 2, 4, 8, 16 nodes? Provide extensive analysis of the speedup and efficiency results.

Question 3: Below is nodes in permutation network. Link below nodes using exchange (i.e, negation the lowest bit). Provide as least one not accessible path between two nodes.
