Large rendering farms and HPC will have distributed memory to split rendering or to maximize performance. - \subsection{} + \subsection*{D} Distributed is easier to scale because the cluster can have nodes added or removed easily without affecting the other nodes. \section{Question 3} - + \subsection*{A} + Concurrency: 8\\ + Critical path length: 4\\ + Maximum achievable speedup: \(15/4\) \\ + Minimum number of processes needed: 8\\ + Maximum achievable speedup if the number of processes is limited to: \\ + 2- \(15/8\)\\ + 4- \(15/5\)\\ + 8- \(15/4\)\\ + \subsection*{B} + Concurrency: 8\\ + Critical path length: \\ + Maximum achievable speedup: \\ + Minimum number of processes needed: \\ + Maximum achievable speedup if the number of processes is limited to: \\ + 2- \(15/8\)\\ + 4- \(15/5\)\\ + 8- \(15/4\)\\ + \subsection*{C} + Concurrency: 8\\ + Critical path length: 7\\ + Maximum achievable speedup: \(14/7\)\\ + Minimum number of processes needed: \\ + Maximum achievable speedup if the number of processes is limited to: \\ + 2- \(14/10\)\\ + 4- \(14/8\)\\ + 8- \(14/7\)\\ + \subsection*{D} + Concurrency: 2\\ + Critical path length: 8\\ + Maximum achievable speedup: \(15/8\)\\ + Minimum number of processes needed: 2\\ + Maximum achievable speedup if the number of processes is limited to: \\ + 2- \(15/8\)\\ + 4- \(15/8\)\\ + 8- \(15/8\)\\ + \section{Question 4} + \subsection*{A} \end{document}
