SC86 — 48-Core Granite Rapids CFD Node with Configurable Memory and Storage for ANSYS Fluent

The SC86 node brings latest-generation Intel compute to ANSYS Fluent, built on a 48-core Intel® Xeon® 6741P (Granite Rapids) with configurable memory and NVMe storage. You choose the balance that fits your work — from 128 to 256 GB of fast DDR5 ECC RAM, and from 2 to 4 datacenter NVMe drives (960 GB to 1.92 TB each) — on a modern, high-bandwidth platform with a high core count. When you want current-generation performance and strong parallelism, tailored to your case size, SC86 is the choice.

It is a modern, high-core, configurable single-socket tier: newest-generation cores, a high core count, flexible memory and storage, and the wide bandwidth of the Granite Rapids platform.

Specifications

SC86 uses a modern Xeon 6741P on Intel's Granite Rapids platform: 48 cores at 2.5 GHz, with the wide multi-channel DDR5 bandwidth and PCIe connectivity of the current generation. Memory and storage are configurable — from 128 to 256 GB of DDR5 ECC RAM, and from 2 to 4 NVMe datacenter drives — so the node can be matched to your workload rather than fixed to one balance.

What's included with SC86

Every SC86 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

SC86 is a modern, high-core, configurable single-socket tier. It suits:

• Large meshes solved fast — 48 modern Granite Rapids cores spread the work for a strong parallel speed-up.

• Workloads you want to right-size — pick the memory and storage that match your case rather than paying for a fixed spec.

• I/O-heavy transient runs — configurable NVMe (up to 4 drives) absorbs frequent timestep writes.

• DDR5-bandwidth-sensitive solving — the modern platform's wide memory bandwidth helps keep 48 cores fed.

With 48 modern cores and wide DDR5 bandwidth, Fluent partitions your mesh across all of them for a strong parallel speed-up, while your chosen memory and NVMe configuration keeps the case in memory and the data flowing.

Configuring SC86: memory and storage

SC86's defining feature is flexibility. In CFD, memory sets the largest mesh you can run — roughly 1 GB of RAM per million cells for a typical steady, single-phase case — while cores determine how fast it solves, and storage holds your case and result data.

• Memory (128–256 GB): choose 128 GB for moderate cases, or 256 GB to hold larger meshes and more memory-hungry physics (transient, multiphase) in memory.

• Storage (2–4 NVMe drives, 960 GB–1.92 TB each): choose fewer, smaller drives for lighter workloads, or more and larger drives for long transient runs and larger result sets.

Tell us your cell count, physics, and how much result data you expect, and we'll recommend the memory and storage configuration that fits — then match you to SC86 or another tier as appropriate.

Fast NVMe storage

SC86 uses NVMe datacenter SSDs, which deliver markedly faster read/write than SATA. Loading large geometries and case files, writing solution data, and handling frequent autosaves all run quickly, so a fast solve is never held up by slow disk I/O. Because the drive count and capacity are configurable, you can size storage to your workload — from a responsive baseline to several terabytes for long transient simulations that write data at every timestep.

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 your chosen memory and partition well, those 48 modern cores deliver a strong speed-up.

Why rent instead of buy

Buying the newest-generation hardware means committing to one fixed build. Renting SC86 gives you current-generation, high-core compute — configured to your workload — plus a free course, a month of Claude AI Premium, and a consultation hour, without the capital cost or the upkeep.

How it works — you're in full control

SC86 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 SC86 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 SC86 modern and fast? It's built on Intel's Granite Rapids platform with a 48-core Xeon 6741P and DDR5 ECC memory — current-generation cores, a high core count, and wide memory bandwidth for efficient parallel solving.

How do I choose the memory and storage? Memory is configurable from 128 to 256 GB (roughly 1 GB per million cells for simpler steady cases, so 256 GB holds larger or more complex meshes). Storage is configurable from 2 to 4 NVMe drives at 960 GB–1.92 TB each. Tell us your case size and result-data needs, and we'll recommend a configuration.

How large a mesh can it handle? It depends on your chosen memory — plan around 1 GB per million cells for simpler steady single-phase cases (fewer for transient or multiphase physics). At 128 GB, expect large meshes; at 256 GB, larger ones still. Send us your case for a precise answer.

How is SC86 different from the 32-core Granite Rapids node? Both are modern, configurable Granite Rapids nodes. SC86 steps up to 48 cores for greater parallelism, so it solves large, well-partitioning cases faster.

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.
