SC74

SC74 — 32-Core EPYC CFD Node for Parallel ANSYS Fluent Solves

The SC74 node brings single-socket AMD EPYC parallelism to ANSYS Fluent, pairing a 32-core AMD EPYC™ 7502P (up to 3.4 GHz) with 128 GB of RAM and nearly 2 TB of SATA SSD storage. With a high core count, a large cache, and wide memory bandwidth in one efficient CPU, it spreads moderate-to-large meshes across plenty of parallel compute. When you want solid parallel throughput on a capable single-socket node, SC74 is the choice.

It is a high-core, single-socket tier in our range: a capable EPYC processor, a sensible 128 GB memory budget, and responsive SSD storage — with a clear path up to multi-socket, higher-memory, and GPU nodes as your jobs grow.

Specifications

SC74 uses a single AMD EPYC 7502P: 32 cores in one socket at up to 3.4 GHz, with 128 MB of L3 cache and the wide memory bandwidth and PCIe connectivity the EPYC platform is known for. Behind it, 128 GB of RAM holds moderate-to-large meshes, and two 960 GB SATA SSDs give you nearly 2 TB for case files, solution data, and autosaves.

What's included with SC74

Every SC74 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

SC74 is a high-core, single-socket tier in our range. It suits:

• Moderate-to-large meshes solved in parallel — 32 cores spread the work for a strong speed-up.

• Design iteration and parameter sweeps — more cores means more variants processed per hour.

• Steady and transient runs that fit in 128 GB — wherever the bottleneck is solve throughput, not memory.

• Capable parallel CFD — a high core count in an efficient single-CPU design.

With 32 cores at up to 3.4 GHz and a large 128 MB cache, Fluent partitions your mesh across all of them for a strong parallel speed-up, while EPYC's wide memory bandwidth keeps the cores fed.

Cores vs. memory: choosing SC74

SC74's headline is cores in an efficient single-socket design. 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 128 GB, SC74 is matched to moderate-to-large meshes solved in parallel.

• Want more modern cores at the same memory? See SC58 or SC73 (48-core EPYC "Genoa").

• Need multi-socket core counts? See SC62 (48-core dual Xeon) or SC63 (96-core quad Xeon).

• Need more memory? See SC56 (1 TB) or SC59 (1 TB, 44-core).

• Want GPU acceleration? Our GPU tiers (the SG series) run Fluent's native GPU solver.

Tell us your cell count and physics, and we'll match you to the tier that fits. High core counts pay off most when a case is large enough to partition efficiently — we'll help you confirm SC74 is the right call.

Fast SSD storage

The two 960 GB SATA SSDs give you nearly 2 TB of responsive storage — quick read/write for loading case files, writing solution data, and handling autosaves, so a fast solve isn't held up by slow disk I/O. (If you need the higher throughput of NVMe or larger capacity, ask us about our NVMe-equipped and high-capacity nodes.)

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-socket node, that communication runs entirely on-chip rather than across sockets or a network, keeping parallel overhead low. For moderate-to-large cases that fit in 128 GB and partition well, those 32 cores deliver a strong speed-up.

Why rent instead of buy

For capable parallel CFD on a single-socket node, SC74 gives you a 32-core EPYC processor — plus a free course, a month of Claude AI Premium, and a consultation hour — with an easy step up when your meshes or core needs grow.

How it works — you're in full control

SC74 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 SC74 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 SC74 a good parallel node?
It offers a high 32-core count on a single, efficient EPYC processor with a large 128 MB cache — real parallel throughput for moderate-to-large cases without the cost of a multi-socket server.

How large a mesh can it handle?
With 128 GB of RAM, plan for moderate-to-large meshes — into the 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.

How is SC74 different from the 48-core EPYC nodes?
SC74 uses a 32-core Zen 2 "Rome" EPYC; SC58 and SC73 step up to 48-core Zen 4 "Genoa" processors for more cores and newer-generation per-core performance. Choose SC74 for capable parallel solving at an accessible tier.

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.
