HW5 Grading Policy

$$\begin{gathered} score=\sqrt{scor{e}_{raw}}\ast 10 \\ scor{e}_{raw}=correctness\ast 0.5+performance\ast 0.2+report \end{gathered}$$

Correctness (50%)

• $X$: passed tests
• $N$: total number of tests

$$correctness=\frac{X}{N}\ast 100$$

Performance (20%)

• $T$: time1 + panelty1 + time2 + panelty2 (from both scoreboards)
• $T_i$: student
  $i$'s
  $T$
• $T_{best}$: the minimum
  $T$ of all the students

$$performance=\frac{T_{best}}{T_i}\ast 100$$

Report (30%)

1. (10%) What is your parallelism strategy?
   • Breifly describe how they parallelize the task
2. (10%) If there are 4 GPUs instead of 2, what would you do to maximize the performance?
   • (5%) Given at least 1 method to maximize the performance
   • (5%) Conduct experiments or give reasons why their method will likely improve the performance
3. (10%) If there are 5 gravity devices, is it necessary to simulate 5 n-body simulations independently for this problem?
   • (5%) Answer no
   • (5%) Explain why their answer should be correct
4. (Optional, 5%) Any suggestions or feedback for the homework are welcome.
   • Given at least 1 meaningful suggestions or constructive feedback to the assignment or spec
