NCP-AII Question 23
Select 3You have been tasked with optimizing an AI workload on AMD and Intel servers to achieve maximum performance. Which of the following steps should you take to ensure the servers are tuned appropriately for AI workloads?
- A
Enable NUMA balancing and ensure memory is allocated locally to the CPU where the workload is running.
- B
Disable hyper-threading or SMT (Simultaneous Multi-Threading) to allocate more physical cores to AI processes.
- C
Use the latest GPU driver and CUDA toolkit version compatible with your hardware.
- D
Ensure the BIOS and firmware are updated to the latest version with performance tuning settings applied.
- E
Set the CPU power mode to energy-saving to reduce thermal throttling during AI workload execution.
Show answer and explanation
Correct answers: A, C, D
Explanation
Optimizing AMD and Intel servers for AI workloads requires careful configuration of memory, CPU, and GPU settings. Ensuring NUMA balancing and local memory allocation improves memory performance. Using the latest GPU drivers and CUDA toolkit ensures compatibility and performance optimizations for GPU-accelerated workloads. Updating BIOS and firmware provides access to the latest performance enhancements. However, disabling hyper-threading or enabling energy-saving modes can negatively impact performance and should be avoided unless specific use cases demand otherwise.
- A. Correct.
Enabling NUMA balancing and ensuring local memory allocation improves memory access speed and reduces latency for AI workloads, which is critical for performance on multi-socket AMD and Intel servers.
- B. Incorrect.
Disabling hyper-threading or SMT generally does not improve performance for AI workloads, and in many cases, it can reduce throughput by limiting the number of logical cores available.
- C. Correct.
Using the latest GPU driver and CUDA toolkit ensures compatibility with the AI frameworks and optimal GPU performance, which is crucial for AI workload execution.
- D. Correct.
Updating BIOS and firmware helps unlock the latest optimizations and performance tuning options for AMD and Intel servers, enabling better support for demanding workloads.
- E. Incorrect.
Setting the CPU power mode to energy-saving reduces power consumption but also limits CPU performance, which is counterproductive for AI workloads that require maximum computational power.
