SC32 — 44-Core CFD HPC Node for the Fastest ANSYS Fluent Solves

The SC32 node carries the highest core count in our entire lineup — 44 cores and 88 threads from a pair of Broadwell-generation Xeons — paired with 32 GB of RAM. It is built to solve moderate CFD cases as fast as physically possible in ANSYS Fluent. When your case fits comfortably in 32 GB and raw solve speed is the priority, nothing in the range puts more cores behind it.

It is the maximum-throughput tier: the most cores we offer, focused on the fastest turnaround for moderate cases.

Specifications

The headline is unmatched parallel throughput: 44 physical cores — far more than any other node in the range — on a Broadwell architecture with a large 55 MB cache per CPU. For cases that fit in 32 GB, that means the fastest solves we can offer.

What's included with SC32

Every SC32 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

SC32 is the maximum-throughput, moderate-memory tier. The 44 cores deliver the strongest parallel performance in the lineup, while 32 GB keeps it efficient for cases that do not need a large memory footprint. It suits:

• Moderate meshes solved as fast as possible — spread across 44 cores, a case that fits in 32 GB converges very quickly.

• Large parameter sweeps and design studies — the most cores in the range means the most work done per hour.

• Compute-heavy cases that fit in memory — where the bottleneck is solve time, not RAM.

• Time-critical professional CFD — when turnaround is the absolute priority and the case is moderate in size.

With 44 cores (up to 3.6 GHz turbo) and a large cache, Fluent partitions your mesh across all of them and exchanges boundary data each iteration via MPI — and the more cores sharing the work, the sooner each iteration finishes.

Cores vs. memory: choosing SC32

SC32's headline is cores, not capacity. In CFD, cores determine how fast a case solves, while memory sets the largest mesh you can run — roughly 1 GB of RAM per million cells for a typical steady, single-phase case. With 32 GB, SC32 is matched to moderate meshes solved at maximum speed.

Choose SC32 when your case fits in 32 GB and you want it solved as fast as possible, or when you are running many cases and want the highest throughput. If instead your bottleneck is memory — large meshes, heavy multiphase or combustion, transient cases with many transported scalars — then more cores will not help; you need more RAM. In that case:

• SC33 offers the same 44-core platform with 64 GB for larger cases,

• higher-memory nodes reach 96–128 GB,

• and the 1 TB high-memory node handles very large, memory-bound simulations.

Tell us your cell count, physics, and whether speed or capacity matters most, and we will point you to the right tier.

Fast SSD storage

The two 500 GB SATA SSDs deliver responsive read/write for loading case files, writing data, and handling autosaves — keeping a fast solve from being held up by slow disk I/O, which matters all the more on a high-throughput node like this.

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. The more cores available — as long as each still has enough cells to stay busy — the faster the overall solve, which is exactly what SC32's 44 cores are for.

Why rent instead of buy

For the fastest possible turnaround on moderate CFD work without owning a server, SC32 delivers the cores — with a path to higher-memory nodes when a case needs more capacity.

How it works — you're in full control

SC32 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 SC32 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 SC32 the fastest node? It has the highest core count in the lineup — 44 cores / 88 threads — on a Broadwell architecture with a large 55 MB cache per CPU. For moderate cases that fit in 32 GB, that combination delivers the fastest solves we offer.

Will more cores always make my run faster? Up to a point. Fluent scales well as long as each core has enough cells to stay busy relative to the data it exchanges with neighbors. For moderate meshes that fit in 32 GB, SC32's 44 cores deliver a strong speed-up. For very small cases, the benefit tapers off. We will help you size it right.

How large a mesh can it handle? With 32 GB of RAM, plan for moderate meshes — into the low-to-mid tens of millions of cells for simpler steady single-phase cases, fewer for transient or multiphase physics (about 1 GB of RAM per million cells is a good starting estimate). Send us your case for a precise answer.

What if my case needs more memory? SC33 offers the same 44 cores with 64 GB, and we have nodes up to 128 GB plus a 1 TB high-memory node for large, memory-bound work. We will recommend the right tier so your case gets the capacity — or the speed — it 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.
