SC57

This SC57 spec is essentially the same machine as the RZ1 page I drafted earlier (Ryzen 9 7950X3D, 128 GB, ~4 TB NVMe) — now with its proper SC57 name and a slightly different storage figure. So here it is rewritten under the correct name and fitted into your SC series.

SC57 — High-Clock 16-Core CFD Node with Large 3D V-Cache for Fast ANSYS Fluent Solves

The SC57 node is built for per-core speed in ANSYS Fluent, pairing the AMD Ryzen™ 9 7950X3D — 16 high-clocked cores with AMD's large 3D V-Cache — with 128 GB of RAM and nearly 4 TB of fast NVMe datacenter storage. Where our multi-socket nodes lead with sheer core count, SC57 leads with clock speed and cache: cores running up to 5.7 GHz, backed by a huge L3 cache that can ease memory pressure on the right workloads. When you want fast solves with excellent per-core performance on moderate-to-large cases, SC57 is the choice.

It is the high-clock, large-cache single-CPU tier in our range: strong single-thread speed, a generous 128 GB memory budget, and fast NVMe storage for I/O-heavy transient work.

Specifications

SC57 leads with clock and cache: 16 Zen 4 cores boosting to 5.7 GHz, with 128 MB of L3 via AMD's 3D V-Cache — a large cache that can reduce trips to main memory on cache-friendly CFD workloads. Behind it, 128 GB of RAM holds moderate-to-large meshes, and two 1.88 TB NVMe datacenter SSDs deliver fast read/write for case loading, data writes, and autosaves.

What's included with SC57

Every SC57 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

SC57 is the high-clock, large-cache single-CPU tier in our range. It suits:

• Fast per-core solves — high clock speeds drive quick convergence on cases that don't need huge core counts.

• Moderate-to-large meshes — 128 GB of RAM keeps sizeable steady, transient, and multiphase cases in memory.

• Design iteration and parameter sweeps — strong per-core speed and 16 cores process variants quickly.

• I/O-heavy transient runs — fast NVMe absorbs frequent timestep writes and autosaves without slowing the solve.

With 16 cores boosting to 5.7 GHz and a large 3D V-Cache, Fluent partitions your mesh across the cores for a strong speed-up, while 128 GB of RAM keeps moderate-to-large cases comfortably in memory and fast NVMe keeps data flowing.

Cores, cache, and memory: choosing SC57

SC57's headline is per-core speed and cache, backed by a generous memory budget. In CFD, the resources play different roles:

• Cores and clock determine how fast a case solves. SC57's 16 cores at up to 5.7 GHz give strong per-core throughput.

• 3D V-Cache (128 MB L3) can reduce main-memory traffic on cache-friendly workloads — a potential bonus for some CFD cases, though the benefit varies by physics and mesh.

• Memory (128 GB) sets the largest mesh you can run — roughly 1 GB of RAM per million cells for a typical steady, single-phase case.

• NVMe storage (≈4 TB) keeps I/O fast for large case and data files.

If your priority is fast solves with high per-core performance, SC57 is well matched. Need more cores instead? Step up to our high-core nodes — SC58 (48-core EPYC), SC60 (32-core EPYC), SC62 (48-core dual Xeon), or SC63 (96-core quad Xeon). Want GPU acceleration? See our GPU tiers (GP1, GP2). Tell us your cell count and physics, and we'll match you to the tier that fits.

Fast NVMe storage

The two 1.88 TB NVMe datacenter SSDs give you nearly 4 TB of high-speed storage — and NVMe delivers markedly faster read/write than SATA. Loading large geometries and case files, writing solution data, and handling frequent autosaves all run quickly, so a fast solve is never held up by slow disk I/O. The speed and capacity are especially valuable for transient simulations, which write data at every timestep and produce large files fast.

How parallel solving works on this node

When you run Fluent in parallel, the solver partitions your mesh across all 16 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-chip channels rather than a network, keeping parallel overhead low. With high clock speeds and a large shared cache, those 16 cores deliver strong per-core speed-up on moderate-to-large cases that fit in 128 GB.

Why rent instead of buy

For fast per-core CFD solves with plenty of memory and fast storage, SC57 gives you high-clock modern cores — plus a free course, a month of Claude AI Premium, and a consultation hour — with an easy step to a higher-core or GPU-accelerated node when your needs change.

How it works — you're in full control

SC57 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 SC57 node.

2. Set up your simulation — load your geometry and case, configure your solver settings, and run ANSYS Fluent with all 16 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 SC57 fast?
The Ryzen 9 7950X3D combines 16 cores at high clock speeds (up to 5.7 GHz) with a large 128 MB 3D V-Cache. For cases that fit in 128 GB, that mix of clock speed and cache delivers strong per-core solve performance.

Does the 3D V-Cache help CFD?
It can. The large L3 cache reduces trips to main memory on cache-friendly access patterns, which benefits some CFD workloads — though the gain depends on your physics and mesh. Send us your case and we can advise on what to expect.

How is SC57 different from the high-core nodes?
SC57 prioritizes per-core speed with 16 very fast cores — ideal for cases that don't scale to huge core counts. Nodes like SC58, SC60, SC62, and SC63 prioritize core count for large, well-partitioning cases. We'll help you pick based on your case.

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.

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.
