SC53 — Modern 24-Core, 1 TB CFD Node with High Memory Bandwidth

The SC53 node combines our most modern Intel platform with maximum memory. A single Intel Xeon Gold 5412U (Sapphire Rapids) brings 24 cores and 48 threads of current-generation compute and high-bandwidth 8-channel DDR5 memory, paired with a full 1 TB of RAM and fast NVMe storage. It is built for very large CFD cases that benefit from modern per-core efficiency and high memory bandwidth — not just raw core count.

For CFD, where solver performance is often limited by memory bandwidth as much as by cores, SC53 pairs that bandwidth advantage with the capacity to load the largest meshes.

Specifications

SC53 is built on the newest Intel server architecture in our lineup. It combines 24 high-IPC Sapphire Rapids cores with 8-channel DDR5-4400 memory — delivering far higher memory bandwidth (around 282 GB/s) than the DDR4 nodes — plus 1 TB of RAM, PCIe Gen 5, and fast NVMe storage. For memory-bandwidth-sensitive CFD at large scale, that combination is a real advantage.

What's included with SC53

Every SC53 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

SC53 plays to modern per-core speed, high memory bandwidth, and very large memory, backed by fast storage. It suits:

• Very large meshes — with 1 TB of RAM, meshes into the hundreds of millions of cells fit comfortably.

• Memory-bandwidth-bound cases — many steady and transient Fluent runs are limited by bandwidth, not core count, and this is where SC53 excels.

• Large cases that benefit from modern cores — Sapphire Rapids delivers strong per-core performance and AVX-512 acceleration.

• I/O-heavy transient runs — fast NVMe storage keeps data writes and autosaves from stalling the solve.

• A modern, efficient large-memory machine — for engineers who want current-generation hardware with very large capacity.

With 24 modern cores at up to 3.9 GHz, high-bandwidth DDR5, and 1 TB of RAM, even very large cases both fit and solve efficiently.

Why memory bandwidth matters for CFD

CFD performance is not only about core count. At each iteration, the solver streams large amounts of mesh and field data through the cores — so memory bandwidth often sets the real-world pace. Cores starved for data cannot run at full speed, no matter how many there are.

SC53's 8-channel DDR5-4400 delivers substantially more bandwidth than DDR4 platforms, keeping its 24 modern cores fed and productive. Combined with 1 TB of memory, that means very large, bandwidth-bound cases run efficiently — strong real-world CFD performance at large scale.

• Need more cores for highly parallel work? Our 128-core EPYC node (SC44) offers maximum compute at 1 TB.

• Need maximum storage at 1 TB? Our 40-core Skylake node (SC42) offers 6 TB of SSD.

• Want modern architecture and high bandwidth with 1 TB? SC53 is the pick.

Fast NVMe storage

The two 1.88 TB NVMe SSDs (about 3.76 TB total) deliver very high read/write speeds — far faster than SATA — so loading huge case files, writing large data files, and handling frequent autosaves all happen quickly. With PCIe Gen 5, storage keeps pace with the rest of this modern platform.

How parallel solving works on this node

When you run Fluent in parallel, the solver partitions your mesh across all 24 cores (using algorithms such as METIS), each core solving its share of cells and exchanging boundary data each iteration via MPI. On a single modern CPU, that communication runs over fast on-chip and on-board paths, keeping overhead low — and the high-bandwidth DDR5 memory ensures the cores stay fed, so each works at full speed. With 1 TB of memory, even very large cases load comfortably and solve efficiently.

Why rent instead of buy

A modern Sapphire Rapids server with 1 TB of DDR5 and NVMe storage is a significant purchase that depreciates between projects. Renting matches cost to workload:

For a modern, efficient large-memory CFD node with no hardware to own, SC53 puts current-generation performance on demand — with higher-core nodes available when a case needs them.

How it works — you're in full control

SC53 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 SC53 node.

2. Set up your simulation — load your geometry and case, configure your solver settings, and run ANSYS Fluent with all 24 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

How is SC53 different from SC55? Same modern Sapphire Rapids platform and high memory bandwidth, but SC53 has 1 TB of RAM versus SC55's 768 GB. Choose SC53 when you need maximum memory for very large meshes; SC55 serves smaller large cases for less.

Why choose SC53 over a higher-core 1 TB node? SC53 leads on modern per-core performance and memory bandwidth. Because CFD is often bandwidth-bound, its 24 Sapphire Rapids cores with 8-channel DDR5 deliver strong real-world performance at large scale. For work that genuinely scales to many cores, our 40-core (SC42) or 128-core (SC44) 1 TB nodes are the better fit.

How large a mesh can it handle? With 1 TB of RAM, count on very large meshes — into the hundreds of millions of cells, depending on the physics (allow about 1 GB of RAM per million cells as a guide, more for complex physics). Send us your case for a precise estimate.

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.
