Intel Xeon 6731P Node — Latest-Generation 32-Core CFD Compute with Very High Memory Bandwidth

This node is our newest Intel platform — built on the latest Granite Rapids (Xeon 6) architecture for strong modern compute and, crucially for CFD, very high memory bandwidth. A single Intel Xeon 6731P brings 32 cores and 64 threads of current-generation performance, fed by 8-channel DDR5-6400 delivering around 410 GB/s of bandwidth — paired with 128 GB of DDR5 RAM and fast data-center NVMe storage. For CFD, where solver performance is so often limited by memory bandwidth, this node is built around the bottleneck that matters most.

It is a modern, high-bandwidth node: latest-generation cores, a large cache, and exceptional memory throughput for efficient real-world CFD.

Specifications

This is the most modern Intel server architecture in our lineup. It combines 32 high-IPC Granite Rapids cores with 8-channel DDR5-6400 memory — about 410 GB/s of bandwidth, the highest of any Intel node we offer — a large 144 MB cache, PCIe Gen 5, and fast data-center NVMe storage. For memory-bandwidth-sensitive CFD, that combination delivers strong real-world performance.

What's included

Every rental of this node comes with extras to help you get the most from it:

• A comprehensive CFD course, free — a full training course to sharpen your simulation skills, included at no extra cost.

• One month of Claude AI Premium — AI assistance to support your engineering, scripting, and problem-solving.

• One hour of free CFD consultation — direct time with our CFD engineers to help set up, troubleshoot, or optimize your case.

These come standard with the node — practical support alongside the compute.

What this node is built for

This node plays to latest-generation cores, very high memory bandwidth, and a large cache, backed by fast storage. It suits:

• Bandwidth-bound CFD — most steady and transient Fluent runs are limited by memory bandwidth; 8-channel DDR5-6400 is built for exactly this.

• Compute-intensive moderate-to-large meshes — 32 modern cores at a sustained 3.9 GHz solve quickly.

• Cache-friendly cases — the large 144 MB cache keeps more data close to the cores.

• I/O-heavy transient runs — fast data-center NVMe storage keeps data writes and autosaves from stalling the solve.

• A current-generation, efficient CFD machine — the newest Intel architecture, with strong real-world performance per core.

With 32 latest-generation cores, the highest Intel memory bandwidth in the lineup, and 128 GB of DDR5, moderate-to-large cases solve with excellent efficiency.

Why memory bandwidth matters for CFD

CFD performance is not only about core count. At each iteration, the solver streams large amounts of mesh and field data through the cores — so memory bandwidth often sets the real-world pace. Cores starved for data cannot run at full speed, no matter how many there are.

This node's 8-channel DDR5-6400 delivers around 410 GB/s — the highest of any Intel node we offer — keeping all 32 modern cores fed and productive. For bandwidth-bound CFD, that translates directly into strong real-world solve performance.

A note on memory capacity: at 128 GB, this node is matched to moderate-to-large meshes (allow about 1 GB of RAM per million cells as a guide). Its strengths are bandwidth, modern cores, and cache rather than maximum capacity.

• Need much more memory for very large meshes? Our 512 GB and 1 TB nodes go further.

• Need maximum cores? Our 48-core and 128-core nodes push core count higher.

• Want the newest Intel architecture and very high bandwidth for moderate-to-large CFD? This node is the pick.

Fast data-center NVMe storage

The two 1.92 TB data-center NVMe SSDs (about 3.84 TB total) deliver very high read/write speeds and enterprise-grade endurance — so loading large case files, writing data, and handling frequent autosaves all happen quickly and reliably. With PCIe Gen 5, storage keeps pace with the rest of this modern platform.

How parallel solving works on this node

When you run Fluent in parallel, the solver partitions your mesh across all 32 cores (using algorithms such as METIS), each core solving its share of cells and exchanging boundary data each iteration via MPI. On a single modern CPU, that communication runs over fast on-chip and on-board paths, keeping overhead low — and the exceptional DDR5-6400 bandwidth ensures all 32 cores stay fed, so each works at full speed. The result is strong, efficient real-world CFD performance.

Why rent instead of buy

A latest-generation Granite Rapids server with DDR5 and data-center NVMe is a significant purchase that depreciates between projects. Renting matches cost to workload:

For a current-generation, high-bandwidth CFD node with no hardware to own, this node puts the newest Intel performance on demand — with higher-memory and higher-core nodes available when a case needs them.

How it works — you're in full control

This node is yours to drive directly. You connect over a secure remote desktop connection and run everything yourself, exactly as you would on a local workstation:

1. Connect via remote desktop — you get full remote access to the node.

2. Set up your simulation — load your geometry and case, configure your solver settings, and run ANSYS Fluent with all 32 cores at your command.

3. Run and monitor in real time — start, pause, adjust, and watch the solution as it progresses, with complete control throughout.

4. Keep your results — post-process on the node or download your solution and data files whenever you're ready.

You have full authority over the node for the duration of your rental: we provide the hardware and the support, and you run the simulations your way.

Frequently asked questions

What makes this node strong for CFD? It is built around the metrics that drive real-world CFD speed: the highest Intel memory bandwidth in our lineup (8-channel DDR5-6400, ~410 GB/s), 32 latest-generation Granite Rapids cores at a sustained 3.9 GHz, a large 144 MB cache, and fast data-center NVMe storage.

How large a mesh can it handle? With 128 GB of RAM, plan for moderate-to-large meshes — up to around a hundred million-plus cells for simpler physics (allow about 1 GB of RAM per million cells as a guide, more for complex physics). Its strength is solving those quickly with high bandwidth, not maximum capacity. Send us your case for a precise estimate.

What if I need more memory? For very large meshes, step up to our 512 GB or 1 TB nodes. We will recommend the right tier so your case fits — and still solves fast.

Is my data kept confidential? Yes. Your geometry, case files, and results stay private to you, treated as strictly confidential — and because you run everything yourself over remote desktop, your work stays under your control throughout.
