Weather Research and Forecasting Model (WRF) The Weather Research and Forecasting (WRF) Model is a next-generation mesoscale numerical weather prediction system designed for atmospheric research and operational forecasting applications. It features two dynamical cores, a data assimilation system, and a software architecture supporting parallel computation and system extensibility. The model serves a wide range of meteorological applications across scales from tens of meters to thousands of kilometers. For researchers, WRF can produce simulations based on actual atmospheric conditions (i.e., from observations and analyses) or idealized conditions. WRF offers operational forecasting a flexible and computationally efficient platform while reflecting recent advances in physics, numeric, and data assimilation contributed by developers from the expansive research community.

ANSYS Fluent ANSYS Fluent is a general-purpose computational fluid dynamics (CFD) and multi-physics tool that empowers you to go further and faster as you optimize your product's performance. Fluent software contains the broad physical modeling capabilities needed to model flow, turbulence, heat transfer, and reactions for industrial applications. Fluent covers a broad reach, including special capabilities to model in-cylinder combustion, aero-acoustics, turbomachinery, and multiphase systems. AMD and ANSYS have an ongoing technology partnership to deliver exceptional performance for customers.


Supermicro A+ BigTwin: Where Performance Meets Efficiency for Modern and Complex Applications Compute requirements are increasing, while datacenter space is not.

Supermicro's innovative A+ BigTwin family of servers, powered by AMD EPYC processors, offers incredible core density with a rich feature set. Innovative server design meets innovative CPU architecture to drive new levels of value for the datacenter. • Performance: Supports the high-performance AMD EPYC processors for up to 64 cores/128 threads, up to 4TB of DDR4 memory, and 6 hot-swap drives (4 NVMe and 2 SATA3) per node for the most demanding workloads. • Density: Incredible high-density with up to 4 hot-swappable nodes in a 2U form factor provides flexible and robust IO options – 1G, 10G, 25G, or 100G Ethernet or 100G InfiniBand, and up to 2 additional low-profile PCI-E 4.0 x16 expansion slots per node.


AMD EPYC Processors for High Performance Computing (HPC) The AMD EPYC processor brings a new balance to the datacenter. The highest core count yet in an AMD x86-architecture server processor, large memory capacity, memory bandwidth, and I/O density are all brought together in the right balance to help performance reach new heights. AMD EPYCTM 7Fx2 processors bring high frequencies and very high cache ratios per core to the second generation AMD EPYC family of processors. AMD EPYC 7Fx2 processors build on the large memory capacity, extreme memory bandwidth, and massive IO of the 2nd Generation AMD EPYC family to deliver exceptional HPC workload performance. High Frequency Many HPC applications scale very well with frequency. AMD EPYC 7Fx2 series processors offer both base and boost frequencies up to 500MHz faster than the current other AMD EPYC 7002 series models enabling significant per-core performance.







A+ BigTwin WRF Scalability and Performance

With leadership architecture, 2nd Gen AMD EPYC Series Processors demonstrate very high scalability for HPC applications by supporting 8 channels of memory per processor and PCI-E 4.0. Building on dominant performances at a single node, Figure 1 demonstrates how the AMD EPYC 7F72 CPUs efficiently scale through 4 nodes. The scaling in Figure 1 is showing nearly perfect scaling efficiency. AMD EPYC 7F72 CPUs deliver up to ~103% scaling efficiency at 4 nodes. AMD EPYC 7Fx2 processors are the right choice for maximizing both overall performance and performance per core.

A+ BigTwin ANSYS Fluent Scalability and Performance Building on dominant performances at a single node, Figure 3 demonstrates how the AMD EPYC 7F72 CPUs efficiently scale up through 4 nodes. This scaling is not only efficient but is super-linear for these large Fluent benchmark models. AMD EPYC 7F72 CPUs deliver up to ~102% scaling efficiency at 4 nodes. Super-linear speedup of Fluent is often caused by the availability and use of larger amounts of "fast" memory (e.g., cache or local memory).
