What This Means for Your Simulations

48 Cores means this server can perform 48 calculations simultaneously.

Why this matters: CFD simulations divide your fluid domain into millions of cells. Each core can solve equations for different cells at the same time - more cores = dramatically faster solutions. A simulation that takes 24 hours on a 4-core laptop could finish in 3-4 hours with 48 cores.

Perfect for: Large-scale simulations with 10+ million cells, transient analyses, turbulence modeling, multi-phase flows, and running multiple design studies in parallel.

The 3.8 GHz clock speed determines how fast each core performs individual calculations - higher means faster processing for mesh generation, solving, and post-processing.

Memory (RAM)

128 GB
Type
DDR5

What This Means

128 GB is your simulation's "working space" - it holds all active data: mesh geometry, fluid properties, boundary conditions, and results during solving.

DDR5 provides high-bandwidth data access essential for CFD solvers that read and update millions of cell values thousands of times during iterations. This capacity handles professional CFD work like large steady-state analyses and turbulence modeling - much more than typical 16-32GB PC. More RAM means larger meshes and more complex physics without performance degradation.

High-bandwidth memory for lightning-fast data access

Storage

2 x 2.98 TB
Type
SATA SSD

What This Means

This server has 2 storage drives installed. Each drive is 2.98 TB, giving you a total storage capacity of 5.95 TB.

SATA SSD storage provides extremely fast read/write speeds for your simulation files and results. SSDs are much faster than traditional hard drives - ideal for loading large mesh files and saving iteration data quickly. Multiple drives provide redundancy and can be configured for increased performance or data protection.

Ultra-fast storage for rapid I/O operations

Network Speed

1 Gbit/s

Fast file transfers and remote access. Upload meshes and download results quickly from anywhere.

Monthly Traffic

Unlimited

Generous bandwidth allowance for uploading/downloading large simulation files without limits or overage fees.

Operating System

Windows 11

Pre-installed and ready to use. Compatible with ANSYS, OpenFOAM, and other CFD software.

About This Server

SC73 — 48-Core Modern EPYC CFD Node with 6 TB Storage for Fast ANSYS Fluent Solves

The SC73 node pairs a modern single-socket AMD EPYC processor — 48 cores and 96 threads of Zen 4 compute at up to 3.8 GHz — with 128 GB of RAM and a generous ~6 TB of SATA SSD storage. It combines a high core count, strong per-core speed, a large cache, and wide DDR5 memory bandwidth in a single efficient CPU, backed by ample capacity for case files and results. When you want modern, high-core CPU performance with plenty of storage room, SC73 is the choice.

It is a modern high-core, high-capacity single-socket tier in our range: current-generation EPYC compute, generous storage, and a clear path to higher-memory or GPU nodes when your jobs demand it.

CPU

1 × AMD EPYC™ 9454P — 48 cores / 96 threads, 2.75 GHz base, up to 3.8 GHz boost, 256 MB L3 cache (Zen 4 "Genoa", single socket)

Storage

2 × 2.98 TB SATA SSD

SC73 uses a single AMD EPYC 9454P: 48 modern Zen 4 cores at up to 3.8 GHz, with 256 MB of L3 cache and the wide 12-channel DDR5 bandwidth of the Genoa platform — a strong mix of core count, clock speed, and cache. Behind it, 128 GB of RAM holds large meshes, and two 2.98 TB SATA SSDs give you roughly 6 TB for case loading, data writes, and autosaves.

What's included with SC73

Every SC73 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

SC73 is a modern high-core, high-capacity single-socket tier in our range. It suits:

  • Large meshes solved fast — 48 modern cores at up to 3.8 GHz spread the work for a strong, efficient speed-up.

  • Storage-hungry workflows — roughly 6 TB of capacity holds long run histories, multiple cases, and large result sets.

  • Design iteration and parameter sweeps — high core count and per-core speed process variants quickly.

  • Steady and transient runs that fit in 128 GB — wherever solve throughput and storage room are the priority.

With 48 Zen 4 cores and a large 256 MB cache, Fluent partitions your mesh across all of them for a strong parallel speed-up, while wide DDR5 bandwidth keeps the cores fed and ample SATA storage holds your data.

Cores vs. memory: choosing SC73

SC73's headline is modern cores and storage capacity 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, SC73 is matched to large meshes solved at high speed, with generous storage for the data they produce.

  • Want the same compute with faster NVMe storage? See SC58 (48-core EPYC, 7.5 TB NVMe).

  • Your meshes exceed 128 GB? Step up to SC56 (1 TB) or SC59 (1 TB, 44-core).

  • Need a higher core count? See SC62 (48-core dual Xeon) or SC63 (96-core quad Xeon).

  • 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.

Fast SSD storage

The two 2.98 TB SATA SSDs give you roughly 6 TB of responsive storage — quick read/write for loading large case files, writing solution data, and handling autosaves, so a fast solve isn't held up by slow disk I/O. The generous capacity suits long transient runs and projects that accumulate many cases and result sets. (If you need the higher throughput of NVMe for very I/O-heavy work, see SC58, the NVMe-equipped version of this tier.)

How parallel solving works on this node

When you run Fluent in parallel, the solver partitions your mesh across all 48 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 large cases that fit in 128 GB and partition well, those 48 modern Zen 4 cores deliver a strong speed-up.

Move to a higher-memory or GPU node when a job needs it

For modern, high-core CPU solving with plenty of storage, SC73 gives you a current-generation 48-core EPYC processor — plus a free course, a month of Claude AI Premium, and a consultation hour — with an easy step to a higher-memory or GPU-accelerated node when your needs change.

How it works — you're in full control

SC73 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 SC73 node.

  2. Set up your simulation — load your geometry and case, configure your solver settings, and run ANSYS Fluent with all 48 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 SC73 fast?
The EPYC 9454P combines 48 modern Zen 4 cores at up to 3.8 GHz with a large 256 MB L3 cache and wide DDR5 bandwidth — a strong mix of core count, clock speed, and cache that delivers efficient parallel solve performance.

How is SC73 different from SC58?
Both use the same modern 48-core EPYC 9454P with 128 GB of RAM. SC73 has roughly 6 TB of SATA SSD; SC58 has 7.5 TB of faster NVMe. Choose SC58 when storage throughput matters most; SC73 offers the same compute with ample SATA capacity.

How large a mesh can it handle?
With 128 GB of RAM, plan for 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.
