Why do we have multicore architectures instead of faster serial processors? Why is it important to exploit locality for your parallel code? Does it matter if the architecture that you are using is multicore or memory-distributed architecture? If yes, why? A scientist designs a parallel algorithm and calculated that she would get linear speedups. However, when she implemented the algorithm on a memory-distributed clusters which was shared by many people she got speedups that were much less than linear. Further, running the algorithm multiple times with multiple datasets gave variation in the speedups that she got (some time linear, sublinear, superlinear). Can you think of the reasons of the exhibited performance by the parallel algorithmic implementation? Another scientist created a parallel algorithm that can run on a CPU that is connected to a GPU accelerator. The GPU is connected to a CPU via PCIe bus. CPU has 8 cores. When the scientist ran the graph computation on a CPU – it took 320 minutes. However, when he ran the same computation on a CPU-GPU architecture – it took more than 2 days to run the same simulation. Can you help explain: Possible reasons for this discrepancy i.e. shouldn’t more number of cores on a GPU lead to better speedups as compared to running it on CPU? What can you do to make the performance better? Can you come up with a systematic way that you would solve this problem?

Depth First Search (DFS) operates by selecting a node, then expanding on the initial node and generating its successors. In each subsequent step, DFS expands one of the most recently generated nodes. If this node has no successor, then DFS backtracks and expands a different node. If the sequential search of the tree is done using the DFS described above – how much time will it take (Big O notation is fine) to find the solution if each node search takes single unit of time. If the binary tree shown in second diagram (right) can be divided into two parts where each part processes a single half – how much time it will take to find the solution provided that search of each node again take one unit of time? Is there going to be a speedup? If yes, why? If not, Why not? Explain.
