ABUMPIMP 2024
The 2nd Minisymposium on Applications and Benefits of UPMEM commercial Massively Parallel Processing-In-Memory Platform
August 26-27, 2024
Full day minisymposium at EURO-PAR 2024
Motivation and scope of the minisymposium
In the rapidly evolving landscape of data-intensive applications across diverse fields such as genomics, analytics, and artificial intelligence (AI), traditional compute-centric architectures are increasingly reaching their limits. The bottleneck often lies in the communication between main memory and CPUs, which is constrained by a narrow bus that suffers from high latency and limited bandwidth, with a significant portion of energy consumption attributed to DRAM data movement. A promising solution to these challenges is the integration of robust computing capabilities directly onto the DRAM memory die, known as Processing-in-Memory (PIM) DRAM.
The field of PIM is experiencing dynamic progress, highlighted by efforts such as SAMSUNG’s HPM-PIM and SK Hynix’s AiM Accelerator. These developments underscore the growing momentum in PIM, although it’s important to note that these products are not yet commercialized in real hardware. In this context, UPMEM stands out as a pioneer with the first commercially available PIM architecture. UPMEM’s PIM modules, which seamlessly integrate in place of standard DIMMs, bring massively parallel computing capabilities to the table. Each DRAM chip is equipped with 8 general purpose processors (DPUs) that provide fast access to DRAM banks. In a standard server configuration, 2560 DPUs can accelerate applications by an order of magnitude.
The ABUMPIMP Symposium provides a unique platform to delve into the use of this cutting-edge technology. It aims to showcase how different applications can use PIM to their advantage and the intricacies involved in developing PIM applications. As we prepare for the second edition of the Symposium, we’re committed to enhancing the Symposium experience. Our program begins with two compelling keynotes. The first provides an insightful overview of the UPMEM architecture and delves into the application development process. While similar to last year’s keynote, it will highlight the innovations in the latest version of our product. The second keynote will take a deep dive into the new design and will provide a glimpse into future versions of the UPMEM products. Building on the success of last year, where we explored a wide range of applications, this year we want to spotlight programmability. We have already lined up three speakers who will cover various aspects of this important topic. In addition, the symposium will serve as a platform to showcase our internal research efforts to accelerate Lucene with our PIM DRAM.
Target audience
This event is a unique opportunity for anyone looking to accelerate data-intensive applications, offering insights from both industrial and academic researchers who have first-hand experience with UPMEM technology. Attendees will leave with a deeper understanding of this technology’s value and practical insights into its application potential.
