Question: A student ran numerical simulation on a dual - core computer Smartcache, 3 2 G B RAM ) . Each simulation involve calculation of 2

A student ran numerical simulation on a dual-core computer Smartcache, 32GB RAM). Each simulation involve calculation of 2GB of data and takes about 3 hours. To speed up the calculation, he ran two simulations simultaneously. But it turned out that the computer had taken 8 hours to complete the jobs, i.e., the average time to complete one job is 4 hours. Explain why the performance is poorer than only running one simulation at a time. [12 points]
