1Z0-1072-25 Question 6
Single answerYour research team needs to run a large-scale weather simulation on Oracle Cloud Infrastructure. The application requires extremely low-latency, high-throughput inter-node communication and the ability to scale to multiple bare metal instances in a clustered environment. Which compute shape would best meet these requirements?
- A
A VM.Standard shape with sufficient OCPUs
- B
A BM.GPU shape for GPU-accelerated parallel processing
- C
A BM.Standard shape with high memory capacity
- D
An HPC.BM shape with cluster networking (RDMA) support
Show answer and explanation
Correct answer: D
Explanation
In Oracle Cloud Infrastructure, HPC.BM shapes (sometimes referred to as HPC2.x shapes) include RDMA-based cluster networking, which enables extremely low-latency communication essential for tightly coupled HPC workloads like weather simulations or computational fluid dynamics. These shapes let you scale out to multiple nodes in a cluster while maintaining high performance. Refer to Oracle's HPC documentation for best practices on cluster design and deployment using HPC shapes.
- A. Incorrect.
Incorrect. While VM.Standard shapes can offer considerable flexibility and OCPU configurations, they do not provide the dedicated cluster networking (RDMA) capabilities required for large-scale HPC workloads.
- B. Incorrect.
Incorrect. GPU shapes are ideal for workloads specifically optimized for GPU acceleration (e.g., AI/ML). While they can deliver strong parallel performance, they do not inherently provide the specialized low-latency interconnect (RDMA) that HPC shapes offer for tightly coupled computations across multiple nodes.
- C. Incorrect.
Incorrect. A BM.Standard shape might deliver good performance, but it does not include built-in RDMA for ultra-low-latency communication across a large cluster of nodes. It's typically used for high-performance applications that do not require specialized HPC networking.
- D. Correct.
Correct. HPC.BM shapes are designed especially for high-performance computing clusters on OCI. They provide RDMA-based cluster networking, enabling the low latency and high throughput critical for large-scale distributed simulations such as weather modeling.
