SC54 — 44-Core, 512 GB CFD HPC Node for Very Large ANSYS Fluent Simulations

The SC54 node pairs the highest core count in our Xeon range — 44 cores and 88 threads — with a very large 512 GB of RAM and 2 TB of SSD storage. It is built for very large, memory-heavy CFD cases that need both serious capacity and maximum parallel throughput in ANSYS Fluent. When your mesh is too big for the 128 GB nodes but does not require a full terabyte, SC54 is the right fit — maximum cores with very large memory.

It is a very-large-case tier: 44 cores, half a terabyte of RAM, and the room to take on meshes that smaller nodes cannot hold.

Specifications

SC54 combines 44 Broadwell cores — the highest count in our Xeon lineup, with a large 55 MB cache per CPU — with 512 GB of RAM and 2 TB of SSD. Maximum parallel throughput paired with very large memory for the biggest meshes short of our 1 TB tier.

What's included with SC54

Every SC54 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

SC54 is the very-large-case, maximum-core tier. It suits:

• Very large meshes — with 512 GB of RAM, meshes well into the hundreds of millions of cells fit comfortably, solved by 44 cores.

• Heavy multiphase and combustion — VOF, Eulerian, particle models, detailed chemistry and species transport at full scale.

• Large transient simulations — many time steps across 44 cores, with 2 TB of SSD for the output.

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

• The most demanding cases short of 1 TB — when 128 GB is not enough but a full terabyte is more than you need.

With 44 cores (up to 3.6 GHz turbo) and 512 GB of RAM, very large cases both fit and run, then solve with the maximum parallel throughput of our Xeon range.

Maximum cores with very large memory

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. SC54 leads on cores and pairs them with very large memory: 512 GB loads very large meshes, and 44 cores solve them at maximum Xeon-range speed.

• It is a major step up from the 128 GB flagship (SC40): four times the memory, at the same maximum 44-core throughput.

• Need even more memory? Our 1 TB nodes (40-core Skylake with 6 TB storage, or 128-core EPYC) go further.

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

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 very-large-case node, roomy storage keeps the solve from being held up — or cut short — by a full disk.

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 512 GB of memory behind 44 cores, very large cases load comfortably and solve at maximum Xeon-range speed.

Why rent instead of buy

A dual-CPU server with flagship 44-core Xeons and 512 GB of ECC RAM is a major purchase that depreciates between projects. Renting matches cost to workload:

For teams running very large CFD cases periodically, SC54 puts maximum cores and very large memory on demand — with 1 TB nodes available when a case needs still more.

How it works — you're in full control

SC54 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 SC54 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

How large a mesh can SC54 handle? With 512 GB of RAM, count on very large meshes — well into the hundreds of millions of cells for simpler physics (allow about 1 GB of RAM per million cells as a guide, more for complex physics). And with 44 cores, those large meshes solve at the maximum speed of our Xeon range. Send us your case for a precise estimate.

How is SC54 different from the SC40 flagship? Both use the same 44-core E5-2699 v4 platform. SC40 has 128 GB of RAM; SC54 has 512 GB — four times the memory, for much larger meshes — at the same maximum core count.

When would I need a 1 TB node instead? For the very largest, most memory-bound simulations where even 512 GB is not enough — our 1 TB Skylake and 128-core EPYC nodes go further. 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.
