SC35

SC35 — 44-Core Dual-Xeon CFD Node with 128 GB for Fast, Parallel ANSYS Fluent Solves

The SC35 node delivers strong CPU parallelism with a comfortable memory budget for ANSYS Fluent, pairing two Intel® Xeon® E5-2696 v4 CPUs — 44 cores and 88 threads in total — with 128 GB of RAM and 2 TB of SATA SSD storage. It's built to solve moderate-to-large meshes fast, spreading them across a high core count with enough memory to keep sizeable cases resident. When you want high parallel speed with room for larger cases, SC35 is the choice.

It is the speed-first, comfortable-memory tier on our dual-Xeon platform: a high core count, a generous 128 GB budget, and a clear path up when your meshes grow.

Specifications

SC35 uses two Xeon E5-2696 v4 CPUs in a dual-socket system: 44 cores total at 2.2 GHz base (3.6 GHz turbo) with 55 MB of cache per CPU — enterprise-class Broadwell-EP silicon. With 128 GB of RAM behind those cores, it's matched to moderate-to-large meshes solved at high parallelism.

What's included with SC35

Every SC35 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

SC35 is the speed-first, comfortable-memory tier on our dual-Xeon platform. It suits:

• Moderate-to-large meshes solved fast — spread across 44 cores, a case that fits in 128 GB 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 time, not memory.

• Time-sensitive professional CFD — when turnaround is the priority and the case is moderate-to-large.

With 44 cores at up to 3.6 GHz, Fluent partitions your mesh across all of them for a strong speed-up, while 128 GB keeps sizeable cases comfortably in memory.

Cores vs. memory: choosing SC35

SC35's headline is cores, with a comfortable memory budget to match. 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, SC35 is matched to moderate-to-large meshes solved at high speed.

• Need a leaner memory budget at the same speed? See SC33 (64 GB) or SC34 (96 GB) — same 44-core platform.

• Running larger, memory-bound cases? Step up to SC59 (same class, 1 TB) or SC56 (1 TB high-memory).

• Want an even higher core count? See SC61 (88-core quad Xeon) or SC63 (96-core quad Xeon Platinum).

• 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 1000 GB SATA SSDs give you 2 TB of responsive storage — quick read/write for loading case files, writing solution data, and handling autosaves, so a fast solve isn't held up by slow disk I/O. The capacity suits transient runs that write data at every timestep. (For larger datasets or very I/O-heavy work, our higher-capacity and NVMe-equipped nodes offer more room and speed.)

How parallel solving works on this node

When you run Fluent in parallel, the solver partitions your mesh across all 44 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 moderate-to-large cases that fit in 128 GB, those 44 cores deliver a strong speed-up.

Why rent instead of buy

For fast solves on moderate-to-large CFD work, SC35 gives you 44 dual-Xeon cores and a comfortable 128 GB — plus a free course, a month of Claude AI Premium, and a consultation hour — with an easy step up to a higher-memory node when your meshes grow.

How it works — you're in full control

SC35 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 SC35 node.

2. Set up your simulation — load your geometry and case, configure your solver settings, and run ANSYS Fluent with all 44 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 SC35 fast?
Two Xeon E5-2696 v4 CPUs give 44 cores / 88 threads total at up to 3.6 GHz. For moderate-to-large cases that fit in 128 GB, that parallelism delivers strong solve speed.

How is SC35 different from SC33, SC34, and SC59?
All four use the same 44-core dual-Xeon Broadwell-EP class. They differ in memory: SC33 has 64 GB, SC34 has 96 GB, SC35 has 128 GB, and SC59 has a full 1 TB. Step up as your meshes need more memory.

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.
