SC40 — 44-Core, 128 GB CFD HPC Node: Our Flagship for Large, Fast ANSYS Fluent Simulations

The SC40 node is the flagship of our entire lineup — built to deliver maximum speed and large capacity at once. It pairs 44 cores and 88 threads of Broadwell compute — the highest core count we offer — with a substantial 128 GB of RAM and 2 TB of SSD storage. That means you can load large meshes in ANSYS Fluent and solve them as fast as the range allows, with room for the big data files that large and transient simulations produce.

Where other nodes ask you to trade cores for memory, SC40 gives you the best of both. It is the tier for large, demanding, deadline-driven CFD — the most capable all-rounder we offer.

Specifications

SC40 tops the range on every front: the highest core count (44 cores / 88 threads), a large 55 MB cache per CPU, 128 GB of RAM, and 2 TB of SSD. Maximum parallel throughput combined with the memory and storage to handle large cases — nothing else in the dual-CPU lineup offers more on both axes.

What's included with SC40

Every SC40 rental 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

SC40 is the large-case, maximum-performance tier — the strongest combination of capacity and speed in the range. It suits:

• Large meshes solved as fast as possible — into the high tens of millions of cells, with 44 cores keeping solve times to a minimum.

• Multiphase flows — VOF, Eulerian, and particle models (DPM/DDPM) that demand more memory per cell.

• Combustion and reacting flows — detailed chemistry and species transport at real scale.

• Conjugate heat transfer and thermal models — large coupled fluid-solid domains.

• Long transient simulations — many time steps writing many data files, with 2 TB of SSD to hold the output.

• Large parameter studies on a deadline — the most cores in the range means the most throughput.

With 44 cores (up to 3.6 GHz turbo) and 128 GB of RAM, large cases both fit and run, then solve as fast as the lineup allows.

Maximum on both axes — and how to choose

In CFD, memory sets the largest mesh you can run — roughly 1 GB of RAM per million cells for a typical steady, single-phase case, more for complex physics — while cores set how fast it solves. SC40 leads on both: 128 GB loads large meshes, and 44 cores solve them at maximum speed.

• It is the top of the dual-CPU range: more cores than any other node, at large memory and storage.

• If your case is truly enormous or extremely memory-bound — meshes in the hundreds of millions of cells — our 1 TB high-memory node trades cores for maximum memory.

• If your cases are moderate, a lower node will serve you for less.

Tell us your cell count and physics, and we will match you to the right tier.

Fast, roomy SSD storage

The two 1 TB SATA SSDs (about 2 TB total) give both speed and space: responsive read/write for loading and saving large Fluent files, and enough capacity for long transient runs that write data at many time steps. On a flagship node like this, fast and roomy storage keeps the solve from being held up by disk I/O.

How parallel solving works on this node

When you run Fluent in parallel, the solver partitions your mesh across all 44 cores (using algorithms such as METIS), each core solving its share of cells and exchanging boundary data each iteration via MPI. On a single node, that communication runs through fast on-board channels rather than a network, keeping parallel overhead low. With 128 GB of memory behind 44 cores, large cases load comfortably and solve as fast as the range allows.

Why rent instead of buy

A dual-CPU server with flagship 44-core Xeons, 128 GB of ECC RAM, and 2 TB of SSD is a major purchase that depreciates between projects. Renting matches cost to workload:

For teams running large CFD cases on deadlines, SC40 provides flagship performance on demand — with the 1 TB node available for the occasional extreme-memory case.

How it works — you're in full control

SC40 is yours to drive directly. You connect to the node 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 SC40 node.

2. Set up your simulation — load your geometry and case, configure your solver settings, and run ANSYS Fluent with all 44 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 SC40 the flagship? It tops the range on both axes: the highest core count (44 cores / 88 threads) for the fastest solves, plus 128 GB of RAM and ~2 TB of SSD for large meshes and heavy output. No other node in the dual-CPU lineup offers more cores and large memory together.

How large a mesh can it handle? With 128 GB of RAM, count on large meshes — into the high tens of millions of cells for simpler steady single-phase cases, with complex physics needing more memory per cell and so supporting a somewhat smaller mesh. As a guide, allow about 1 GB of RAM per million cells. Send us your case for a precise estimate.

When would I need the 1 TB node instead? For very large, memory-bound simulations where even 128 GB is not enough. We will tell you honestly which tier your case needs.

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.
