SC59

SC59 — 44-Core, 1 TB Dual-Xeon CFD Node for Large, Memory-Hungry ANSYS Fluent Solves

The SC59 node combines high parallelism with maximum memory for ANSYS Fluent, pairing two Intel® Xeon® E5-2699 v4 CPUs — 44 cores and 88 threads in total — with a remarkable 1 TB of RAM. It's built for the demanding combination of a very large mesh and a strong core count: enough memory to hold cases that overwhelm smaller nodes, and enough cores to solve them at pace. When your case is both large and compute-heavy, SC59 is the choice.

It is the high-core, high-memory tier in our range: two enterprise-class Xeon CPUs, the largest memory budget we offer, and the parallelism to drive very large cases hard.

Specifications

SC59 uses two Xeon E5-2699 v4 CPUs in a dual-socket system: 44 cores total at 2.2 GHz base (3.6 GHz turbo) with 55 MB of cache per CPU — enterprise-class Broadwell-EP silicon. Behind them sits 1 TB of RAM, the largest in our lineup, letting Fluent hold very large meshes and solve them across a strong core count.

What's included with SC59

Every SC59 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

SC59 is the high-core, high-memory tier in our range. It suits:

• Very large meshes solved at pace — 1 TB holds the case, and 44 cores solve it faster than a lower-core high-memory node.

• Complex multiphase and reacting flows — memory-hungry physics that also benefit from strong parallelism.

• Large transient runs — where both capacity and solve throughput matter.

• Demanding production CFD — when a case is large and compute-heavy at the same time.

With 44 cores at up to 3.6 GHz and 1 TB of RAM, Fluent can hold a very large mesh entirely in memory and partition it across all the cores for a strong parallel speed-up.

Memory and cores: choosing SC59

SC59's strength is both — maximum memory and a high core count. 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 — while cores determine how fast it solves. With 1 TB and 44 cores, SC59 is matched to very large cases that also need solving at pace: as a rough guide, hundreds of millions of cells for simpler steady single-phase work, fewer for transient or multiphase physics.

• Want 1 TB with newer cores and NVMe but a lower core count? See SC56 (1 TB, modern 24-core Xeon Gold, NVMe).

• Need an even higher core count at a lower memory budget? See SC61 (88-core quad Xeon) or SC63 (96-core quad Xeon Platinum, 256 GB).

• Want GPU acceleration? Our GPU tiers (GP1, GP2) run Fluent's native GPU solver.

Tell us your cell count and physics, and we'll confirm SC59 is the right fit — it's the strongest match when your case is both large in memory and heavy in compute.

Fast SSD storage

The two 1 TB SATA SSDs deliver responsive read/write for loading large case files, writing solution data, and handling autosaves — keeping a fast solve from being held up by slow disk I/O. With very large cases comes large data; if your work writes especially heavy datasets, let us know and we can advise on the right storage configuration for your job.

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 dual-socket node, that communication runs over fast on-board interconnects between the two CPUs rather than a network, keeping parallel overhead far lower than a multi-machine cluster. On SC59, the 1 TB of RAM lets the solver hold a very large mesh entirely in memory while those 44 cores work through it — the combination this node is built for.

Why rent instead of buy

A 1 TB, 44-core server is a major investment to own and maintain — and for many teams, the very large cases that need it are occasional rather than constant. Renting SC59 gives you that capacity and parallelism on demand — plus a free course, a month of Claude AI Premium, and a consultation hour — without the capital cost or the upkeep.

How it works — you're in full control

SC59 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 SC59 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 SC59 special?
It combines the largest memory in our range (1 TB) with a high 44-core count. That lets Fluent hold a very large mesh in memory and solve it faster than a high-memory node with fewer cores — ideal for cases that are large and compute-heavy at once.

How is SC59 different from SC56?
Both offer 1 TB of RAM. SC56 uses a modern 24-core Xeon Gold with NVMe storage; SC59 uses a 44-core dual Broadwell-EP for greater parallelism on large memory-bound cases. Choose SC59 when you need more cores behind the 1 TB; choose SC56 for newer cores and faster NVMe.

How large a mesh can it handle?
With 1 TB of RAM, plan for very large meshes — into the hundreds 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.

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.
