SC70

SC70 — High-Clock 8-Core CFD Node with Fast NVMe for Accessible ANSYS Fluent Solves

The SC70 node offers fast per-core performance for ANSYS Fluent in a compact, accessible package, pairing an 8-core Intel® Core™ i9-9900K (up to 5.0 GHz) with 64 GB of RAM and 2 TB of fast NVMe storage. With high clock speeds and quick NVMe I/O, it's well suited to small-to-moderate cases where per-core speed and responsive storage matter more than a high core count. When you want a fast, accessible node for everyday CFD, SC70 is the choice.

It is the high-clock, compact entry tier in our range: strong single-thread speed, a sensible 64 GB memory budget, and fast NVMe storage — with a clear path up to higher-core, higher-memory, and GPU nodes as your needs grow.

Specifications

SC70 uses a Core i9-9900K: 8 cores reaching up to 5.0 GHz for strong per-core speed. Behind it, 64 GB of RAM holds small-to-moderate meshes, and two 1 TB NVMe SSDs deliver fast read/write for case loading, data writes, and autosaves.

What's included with SC70

Every SC70 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

SC70 is the high-clock, compact entry tier in our range. It suits:

• Small-to-moderate meshes solved quickly — high clock speeds drive fast per-core convergence.

• Learning and everyday CFD — an accessible node for tutorials, prototyping, and routine work.

• Cases that favor clock over core count — smaller models that don't scale to many cores.

• I/O-responsive workflows — fast NVMe keeps case loading and data writes quick.

With 8 cores at up to 5.0 GHz, Fluent partitions your mesh across them for a solid per-core speed-up on small-to-moderate cases, while fast NVMe keeps data flowing.

Cores, clock, and memory: choosing SC70

SC70's headline is clock speed on a compact core count. In CFD, cores and clock 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 64 GB and 8 fast cores, SC70 is matched to small-to-moderate cases solved quickly.

• Need more cores at high clocks? Step up to SC57 (16-core, 5.7 GHz, 128 GB).

• Need more memory? See SC72 (128 GB) or SC56 (1 TB high-memory).

• Need a high core count? See SC58 (48-core EPYC), SC62 (48-core dual Xeon), or SC63 (96-core quad Xeon).

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

Fast NVMe storage

The two 1 TB NVMe SSDs give you 2 TB of high-speed storage — and NVMe delivers markedly faster read/write than SATA or HDD. Loading geometries and case files, writing solution data, and handling autosaves all run quickly, so a fast solve is never held up by slow disk I/O. The speed is especially welcome on a fast-clock node, keeping storage from becoming the bottleneck.

How parallel solving works on this node

When you run Fluent in parallel, the solver partitions your mesh across all 8 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. For small-to-moderate cases that fit in 64 GB, those 8 high-clocked cores deliver a solid speed-up.

Why rent instead of buy

For accessible, fast-clock CFD on small-to-moderate cases, SC70 gives you high per-core speed and fast NVMe storage — plus a free course, a month of Claude AI Premium, and a consultation hour — with an easy step up when your meshes grow.

How it works — you're in full control

SC70 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 SC70 node.

2. Set up your simulation — load your geometry and case, configure your solver settings, and run ANSYS Fluent with all 8 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

Who is SC70 for?
Anyone who wants a fast, accessible node for small-to-moderate CFD cases — work that benefits from high clock speed and quick NVMe storage more than from a high core count.

How large a mesh can it handle?
With 64 GB of RAM, plan for small-to-moderate meshes — into the low 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.

Why choose SC70 over a higher-core node?
SC70's strength is per-core speed on a compact, cost-effective node. For smaller cases that don't scale to many cores, high clocks deliver quick turnaround. As your cases grow, higher-core or higher-memory nodes take over.

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.
