Galactica 3000, is a galaxy simulator developed by the (fictitious) computational astrophysics institute at GMU. It is used to model the evolution of galaxies. A simulation consists of two main parts: Gravitational calculations (80% of the runtime): These are parallelizable and can be sped up by adding more processors. Black hole collision predictions (20% of the runtime): Due to the complexity of interactions, this part is not parallelizable. The institute is considering purchasing a new supercomputer with 16 processors to speed up the simulation. The director asks you to evaluate the expected speedup of Galactica 3000 when run on this new hardware. Question 1: Using Amdahl's law, calculate the theoretical speedup of the simulation on the 16-processor supercomputer. Question 2: Suppose the engineers manage to improve the code so that 95% of the runtime becomes parallelizable. Recalculate the theoretical speedup for this improved version. Question 3: The director wants the simulation to run 10× faster than the current version. Is it possible with the 16-processor supercomputer? If not, how much of the program must be parallelizable to achieve this goal?
A mutuаl fund hаs purchаsed 300 shares оf stоck X at $600 per share, 400 shares оf stock Y at $500 per share, and 500 shares of stock Z at $400 per share, while holding $120,000 in cash. The mutual fund has issued 2,500 shares. If the fund has no liabilities, calculate the NAV. [Note: Do not type your answer in Canvas]
