SC62 — 48-Core Dual-Xeon CFD Node for Highly Parallel ANSYS Fluent Solves

The SC62 node delivers strong CPU parallelism for ANSYS Fluent, pairing two Intel® Xeon® Platinum 8168 CPUs — 48 cores and 96 threads in total — with 128 GB of RAM. Built to spread large meshes across a high core count, SC62 drives fast parallel solves where throughput matters most. When your case partitions well and you want serious parallel scale without stepping up to the full quad-socket node, SC62 is the choice.

It is the high-core, balanced-memory tier on our multi-socket platform: two enterprise-class Xeon Platinum CPUs, a sensible 128 GB memory budget, and a clear path up to more cores and memory when your jobs grow.

Specifications

SC62 uses two Xeon Platinum 8168 CPUs in a dual-socket system: 48 cores total at 2.7 GHz base (3.7 GHz turbo) with 33 MB of cache per CPU — enterprise-class Skylake-SP silicon built for heavily parallel workloads. With 128 GB of RAM behind those cores, it's matched to large meshes solved across strong parallelism.

What's included with SC62

Every SC62 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

SC62 is the high-throughput, balanced-memory tier on our multi-socket platform. It suits:

• Large meshes solved fast — spread across 48 cores, a well-partitioned case converges quickly.

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

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

• Highly parallel professional CFD — when core count drives your turnaround.

With 48 cores at up to 3.7 GHz, Fluent partitions your mesh across all of them for a strong parallel speed-up, while 128 GB of RAM keeps large cases comfortably in memory.

Cores vs. memory: choosing SC62

SC62's headline is cores, backed by a balanced memory budget. 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, SC62 is matched to large meshes solved at high parallelism.

• Need more cores and memory? Step up to SC63, the quad-socket node with 96 cores and 256 GB.

• Running a very large, memory-bound case? Ask us about our 1 TB high-memory node.

• Want GPU acceleration instead of pure CPU scale? Our GPU tiers (GP1, GP2) run Fluent's native GPU solver.

Tell us your cell count and physics, and we'll match you to the tier that fits. Very high core counts pay off most when a case is large enough to partition efficiently — for smaller cases, parallel overhead can outweigh the benefit, so we'll help you confirm SC62 is the right call.

Fast SSD storage

The two 1000 GB SATA SSDs deliver responsive read/write for loading case files, writing solution data, and handling autosaves — keeping a fast solve from being held up by slow disk I/O. If your work involves long transient runs that write very large datasets, let us know and we can advise on the right storage configuration for your job.

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 dual-socket node, that communication runs over fast on-board interconnects between the two CPUs rather than a network, keeping parallel overhead far lower than a multi-machine cluster. For large cases that fit in 128 GB and partition well, those 48 cores deliver a substantial speed-up.

Why rent instead of buy

A dual-socket, 48-core server is a significant investment to own and maintain. Renting SC62 gives you that parallel scale on demand — plus a free course, a month of Claude AI Premium, and a consultation hour — with an easy step up to SC63 when your meshes grow.

How it works — you're in full control

SC62 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 SC62 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 SC62 fast?
SC62 pairs two Xeon Platinum 8168 CPUs for 48 cores / 96 threads total, at up to 3.7 GHz. For large cases that partition well and fit in 128 GB, that parallelism delivers strong solve throughput.

How is SC62 different from SC63?
Both use the Xeon Platinum 8168 platform. SC62 is the dual-socket node — 48 cores and 128 GB; SC63 is the quad-socket node — 96 cores and 256 GB. Step up to SC63 when you need more cores or memory.

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.

Will my case use all 48 cores effectively?
It depends on size. High core counts pay off most on large meshes that partition efficiently; smaller cases may not scale all the way to 48 cores, where parallel overhead can eat into the gain. Send us your setup and we'll advise whether SC62 or a different tier is the better fit.

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.
