SC84
Unmatched Performance
Built for demanding CFD simulations and computational workloads
Processor
The brain of your simulation power
What This Means for Your Simulations
This server has 2
physical CPUs installed.
Each CPU has 20 cores and
40 threads, giving you a total of
40 cores and
80 threads.
Why this matters: Think of cores as individual workers - with
40 cores, this server can perform
40 calculations at exactly the same time. CFD
simulations divide your fluid domain into millions of cells, and each core can solve
equations for different cells simultaneously, dramatically reducing solution time.
Perfect for: Large-scale industrial simulations with 10+ million cells,
complex transient analyses (time-dependent flows), multi-phase simulations, turbulence
modeling with fine meshes, and running multiple design iterations in parallel. This
dual-CPU configuration delivers enterprise-grade computational power - a simulation that
takes 48 hours on a typical workstation could finish in 4-6 hours here.
The 3.7 GHz clock speed determines how fast each
core processes individual calculations. Higher clock speeds improve both single-threaded
operations (mesh generation, post-processing) and the per-core efficiency during parallel
solving.
Industry-standard CPU benchmark • Higher scores = Faster simulations
Memory (RAM)
What This Means
64 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
standard to medium simulations with headroom for mesh refinement - significantly more
than typical workstations with 16-32GB. Adequate RAM prevents solver crashes and slow
virtual memory usage.
High-bandwidth memory for lightning-fast data access
Storage
What This Means
This server has
2 storage drives installed.
Each drive is 1 TB, giving you a total
storage capacity of 2 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
Fast file transfers and remote access. Upload meshes and download results quickly from anywhere.
Monthly Traffic
Generous bandwidth allowance for uploading/downloading large simulation files without limits or overage fees.
Operating System
Pre-installed and ready to use. Compatible with ANSYS, OpenFOAM, and other CFD software.
About This Server
Dual Xeon Gold 6138 Node — 40-Core Skylake CFD Compute
This node pairs two Intel Xeon Gold 6138 processors for 40 cores and 80 threads of Skylake-generation compute — a more modern Xeon architecture than our Broadwell and Ivy Bridge nodes, with AVX-512 and higher memory bandwidth. Combined with 64 GB of RAM and 2 TB of SSD storage, it is built to solve moderate-to-larger CFD cases fast in ANSYS Fluent, putting plenty of modern parallel throughput behind cases that fit comfortably in memory.
It is a high-core, moderate-memory tier: strong parallel performance on a newer Xeon platform, at an efficient memory budget.
Specifications
Component | Specification |
|---|---|
CPU | 2 × Intel® Xeon® Gold 6138 — 20 cores / 40 threads each (40 cores / 80 threads total), 2.0 GHz base, up to 3.7 GHz turbo, 27.5 MB cache each, AVX-512 (Skylake-SP) |
Memory | 64 GB RAM |
Storage | 2 × 1 TB SSD — ~2 TB total |
This node delivers 40 Skylake-SP cores — a newer Xeon architecture than our Broadwell and Ivy Bridge nodes, with AVX-512 and 6-channel memory for stronger throughput — at a focused 64 GB of memory. The result is plenty of modern parallel compute for cases that fit comfortably in RAM.
What's included
Every rental of this node 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
This node is a high-throughput, moderate-memory tier on a modern Xeon platform. It suits:
Moderate-to-larger meshes solved fast — 40 Skylake cores spread the work for strong parallel speed-up on cases that fit in 64 GB.
Design iteration and parameter sweeps — more cores means more variants processed per hour.
Steady and transient runs that fit in 64 GB — where the bottleneck is solve time, not memory.
Cases that benefit from AVX-512 — Skylake's vector acceleration helps compute-heavy CFD.
Professional CFD at moderate scale — strong parallel performance for everyday demanding work.
With 40 cores at up to 3.7 GHz and AVX-512, cases that fit in 64 GB solve with strong parallel performance on a modern architecture.
Where this node fits — cores and architecture vs. memory
In CFD, cores and architecture set 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, more for complex physics. This node leads on core count and a modern Skylake architecture at a moderate 64 GB:
It is a step up in architecture from the Broadwell and Ivy Bridge nodes — AVX-512 and higher memory bandwidth — at the same kind of core count.
Need much more memory for larger meshes? Our higher-memory nodes, including a 40-core Skylake node with 1 TB of RAM and 6 TB of storage, go further.
Want the newest architecture and highest bandwidth? Our Sapphire Rapids and Granite Rapids nodes step up again.
Tell us your cell count and physics, and we will match you to the right tier.
SSD storage
The two 1 TB SSDs (about 2 TB total) provide solid-state read/write for loading case files, writing data, and handling autosaves — responsive and roomy, with ample space for results. (For the very fastest storage, our NVMe-equipped nodes go further.)
How parallel solving works on this node
When you run Fluent in parallel, the solver partitions your mesh across all 40 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-board channels rather than a network, keeping parallel overhead low. With 40 Skylake cores and AVX-512, cases that fit in 64 GB solve with strong parallel performance.

Frequently asked questions
What makes this node a good choice? It combines 40 cores with a more modern Skylake architecture than our Broadwell and Ivy Bridge nodes — including AVX-512 and higher memory bandwidth — for strong parallel performance on cases that fit in 64 GB.
How large a mesh can it handle? With 64 GB of RAM, plan for moderate-to-larger meshes — up to around 50–60 million 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.
What if my case needs more memory? For larger meshes, step up to our higher-memory nodes — including a 40-core Skylake node with 1 TB of RAM — or our newer Sapphire Rapids and Granite Rapids platforms. We will recommend the right 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.
