1Z0-1072-25 Question 12
Single answerA manufacturing firm is migrating its batch HPC workloads to Oracle Cloud Infrastructure. These workloads run large-scale engineering simulations requiring high-performance compute, ultra-low latency cluster networking, and ephemeral local storage for large intermediate datasets. The firm also wants to ensure cost efficiency by spinning down environments when not in use. Which OCI compute shape best fits these requirements?
- A
VM.Standard.E4.Flex
- B
VM.GPU.A10
- C
BM.Standard.E4
- D
BM.HPC3
Show answer and explanation
Correct answer: D
Explanation
In Oracle Cloud Infrastructure, HPC shapes such as BM.HPC3 deliver high-performance computing capabilities combined with an ultra-low latency cluster network and local NVMe storage, which is crucial for large-scale engineering simulations. This makes BM.HPC3 the most suitable choice for compute-intensive batch workloads that need both massive performance and efficient scaling. For more information on HPC shapes and best practices, refer to the official OCI documentation on HPC solutions.
- A. Incorrect.
Option 1: VM.Standard.E4.Flex provides flexible CPU and memory configurations and is suitable for many general-purpose workloads. However, it does not offer the specialized HPC cluster networking or the large ephemeral local storage required by HPC workloads.
- B. Incorrect.
Option 2: VM.GPU.A10 is designed for GPU-intensive tasks such as deep learning and rendering, but not primarily for CPU-bound engineering simulations. It also lacks dedicated HPC cluster networking, making it suboptimal for an HPC workload that depends on low-latency interconnects.
- C. Incorrect.
Option 3: BM.Standard.E4 offers bare metal access with high performance, but it does not include specialized HPC cluster networking. While bare metal generally provides more control and performance than VMs, HPC workloads requiring ultra-low latency inter-node communication usually require a shape specifically designed for HPC.
- D. Correct.
Option 4: BM.HPC3 is purpose-built for HPC workloads, featuring low-latency cluster networking and high-performance local (ephemeral) storage. It is ideal for engineering simulations and other performance-intensive applications that need specialized networking and fast local disk access.
