NCA-AIIO Question 77
Select 4You are tasked with presenting the results of a GPU utilization analysis for an AI training cluster to your team. The goal is to identify underutilized GPUs and optimize resource allocation. Which of the following approaches would be most effective to create clear and actionable visualizations?
- A
Use a line chart to track GPU utilization trends over time for all nodes in the cluster.
- B
Create a scatter plot comparing GPU utilization rates and memory usage for each node.
- C
Generate a pie chart showing the proportion of GPUs operating at low, medium, and high utilization levels.
- D
Present a table with raw utilization and memory usage data for each GPU in the cluster.
- E
Use a bar chart to compare average GPU utilization across different workloads in the same cluster.
Show answer and explanation
Correct answers: A, B, C, E
Explanation
Creating visualizations, such as line charts, scatter plots, pie charts, and bar charts, is essential for effectively communicating GPU utilization patterns, correlations, and resource allocation insights. While tables can provide detailed data, they are not as effective for conveying actionable insights due to their lack of visual clarity.
- A. Correct.
A line chart effectively shows trends over time, which helps identify patterns and resource underutilization across multiple nodes.
- B. Correct.
A scatter plot can reveal correlations between GPU utilization and memory usage, providing insights into potential bottlenecks or inefficiencies.
- C. Correct.
A pie chart is useful for summarizing the proportion of GPUs operating at different utilization levels, offering a high-level view of cluster performance.
- D. Incorrect.
While a table provides detailed raw data, it is less effective for quickly identifying patterns or trends compared to visualizations like charts and graphs.
- E. Correct.
A bar chart enables comparison of GPU utilization across workloads, which can highlight which workloads are underutilizing or overutilizing resources.
