- Performance Analysis of HPC applications on the Aurora Supercomputer . . .
For CPU-only applications or hybrid CPU GPU applications with CPU memory bandwidth-bound kernels, performance improves with higher bandwidth In these cases, HBM outperforms DDR, Flat HBM memory mode outperforms Cache mode, and SNC4 clustering mode outperforms Quad mode, as demonstrated in HACC and CPU-only QMCPACK and BFS
- High Bandwidth Memory - Wikipedia
High Bandwidth Memory (HBM) is a computer memory interface for 3D-stacked synchronous dynamic random-access memory (SDRAM) initially from Samsung, AMD and SK Hynix
- High Bandwidth Memory Can Make CPUs the Desired Platform for AI and HPC
Recent Intel and third-party benchmarks now provide hard evidence that the upcoming Intel® Xeon® processor Max Series, with fast, high bandwidth HBM2e memory and Intel® Advanced Matrix Extensions, can match the performance of GPUs for many AI and HPC workloads
- How High-Bandwidth Memory Will Break Performance Bottlenecks
Intel recently announced that High-Bandwidth Memory (HBM) will be available on select “Sapphire Rapids” Xeon SP processors and will provide the CPU backbone for the “Aurora” exascale supercomputer to be sited at Argonne National Laboratory
- Understanding High Bandwidth Memory (HBM): Advantages and Future Prospects
Utilizing a unique 3D stacking architecture, HBM supports bandwidths exceeding 1 TB s while consuming less power than traditional memory This blog post explores the benefits of HBM, including its role in gaming, artificial intelligence, and supercomputing
- Understanding High Bandwidth Memory (HBM): Video RAM of GPU - Substack
HBM, short for High Bandwidth Memory, represents a groundbreaking innovation in CPU GPU memory chips Unlike traditional DDR memory, HBM adopts a vertically stacked architecture, akin to a "skyscraper design" compared to DDR's "single-story house" layout
- High-Bandwidth Memory (HBM) delivers impressive performance gains
HBM was designed to address the lagging performance and power of standard dynamic random-access memory (DRAM), compared to central processing unit (CPU) and graphics processing unit (GPU)
- Characterizing the performance benefit of hybrid memory system for HPC . . .
We identify three factors that impact performance benefits from the HBM-DRAM memory system of the KNL processors We show that applications with regular memory access patterns largely benefit the HBM On the contrary, applications with irregular access patterns may have performance degradation from the high latency in HBM
- High Bandwidth Memory: Concepts, Architecture, and Applications
High-Bandwidth Memory (HBM) is a 3D-stacked DRAM designed for ultra-high bandwidth and efficiency Used in GPUs, AI, and HPC, it tackles memory bottlenecks by stacking dies vertically near processors This article explores its evolution, architecture, and impact on modern computing What is HBM?
- High Bandwidth Memory | Ohio Supercomputer Center
In addition to the DDR5 memory that is available on all other nodes on our systems, these CPUs also contain 128 GB of high bandwidth memory HBM2e which should especially speedup memory-bound codes All nodes on Cardinal are configured clustering in SNC4 mode
