1st Workshop on High Performance Fabrics
31st IEEE International Conference on High Performance Computing, Data, & Analytics
Dec 18, 2024
Bengaluru, India
Workshop on High Performance Fabrics (FABRICS 2024)
In conjunction with the 31st IEEE International Conference on High-Performance Computing, Data, & Analytics (HiPC 2024)
Description
The word “Fabrics” is perhaps the most used or abused word in Computing today. A Fabric is, as its name implies, a web of multiple devices in a cluster using some physical level connectivity with transport and protocol layers built on top of it. Computing, in general, and High Performance Computing in particular have moved over the years from proprietary cluster interconnects to more popularly, InfiniBand and Ethernet.
However, the communication fabric closer to the CPUs or Accelerators (including GPUs) is where the focus has been of late with the AI era. Compute Express Link (CXL) is a memory semantic fabric that has been developed to solve multiple challenges in computing related to capacity and bandwidth of memory, as well as the need to disaggregate memory. When it comes to connecting GPUs with each other, NVLink has become the most popular communication fabric. However, there have been recent advancements in this space with the formation of the Ultra Accelerator Link, or UALink, consortium to connect accelerators and allow sharing of memory between them and CPUs. Ethernet is further being enhanced by the Ultra Ethernet Consortium (UEC) to build a low-latency, lossless variant of Ethernet.
The Fabrics for HPC/AI workshop will be a half-day workshop with the aim of exploring the novel research ideas around this very rich space of fabrics and the research happening in operating systems, virtualization and manageability in related areas.
Keynote 1 : Fabric Challenges in AI Clusters
Speaker : Manoj Wadekar, Meta
Abstract : This talk will focus on the following areas :
- AI clusters are creating new fabrics in Datacenters.
- AI Fabrics pushing network, memory, chip-to-chip, die-to-die interconnects
- Exponential growth in AI clusters and Fabric limitations driving unique data center solutions creating opportunities for innovation.
Bio : Manoj Wadekar (Meta) is a leading figure in Meta’s technology division, focusing on advanced computing solutions and AI integration. His expertise in system architecture and data management has driven significant innovations in Meta’s infrastructure, enhancing the performance and scalability of their computing systems.
Keynote 2 : Harnessing power of advanced next-gen fabrics to break memory wall with TCO optimized solution
Speaker : Vishal Tanna, Micron
Abstract : This talk will cover the following areas
- Fabrics for Memory and Their Necessity
- The memory wall problem and the solutions being explored to address it.
- Evolution of CXL and how it can help mitigate the memory wall issue.
- Workload Analysis
- Analysis of different workloads that are either memory capacity or bandwidth bound.
- CXL for Pooling and Sharing
- Investigation into how CXL supports resource pooling and sharing, and the role of FAMFS in these features.
- Emerging Fabrics
- Introduction to UALink and its benefits.
Bio: Vishal is the Director of engineering at Micron. He is currently leading the R&D teams working on various aspects of CXL interface-based product development. Previous to this, he lead the team which delivered Micron’s first ever PCIe based NAND flash controller to complex enterprise NVMe SSDs. He is an expert in fabrics like PCIe, CXL and NVMe
