Emerging HPC and data center applications, in domains such as artificial intelligence (AI), data analytics, scientific computing, enterprise computing etc., are experiencing rapid growth regarding the amount of data to be processed combined with algorithm complexity. As a promising solution, industry and academia are moving toward more and more heterogeneous architectures based on various accelerators in many different parts of hardware infrastructures. This creates opportunities for the flexible accelerators to find a new path to provide a significantly better performance per watt than other solutions.
One of the main goals of this workshop is to better understand present, and future challenges for FPGA/xPU accelerator devices, and at the same time create awareness and engagement around some of the initiatives led by professionals from academia and the industry. That will allow collaborative activities between academia and industry, and the creation of placeholders for ongoing international research projects, and follow-up their evolution along the timesharing knowledge.
The workshop will include technical presentations to develop a complete view of the ecosystem, from software to hardware, and build on top of it the next generation of HPC and data center systems.
More heterogeneity is required, furthering the current strong focus on DPUs, GPUs (mainstream), and application specific-accelerators such as TPUs, etc.
Proven chiplets/2.5D/3D packaging technologies open the door to more flexible heterogeneous integration into mainstream SoCs and super-chips.
Algorithmic innovations are happening at a fast pace such that it becomes challenging to balance specialization versus generality as well as fixed versus reconfigurable hardware designs.
The purpose of this workshop is to provide an overview of the advancements and challenges in the HPC and data center domains by using FPGA/xPU accelerators, taking into account considerations and points of view from academia and industry. As part of this, and due to the inherent complexity of managing these devices reducing their accessibility significantly compared to other kinds of accelerators, this workshop aims to tackle the needs of relevant stakeholders and ecosystems to reverse, or at least alleviate this situation.
This workshop offers a forum for researchers and developers to discuss how all the different pieces of the ecosystem impacts on spreading and popularizing the use of the FPGA/xPU accelerators as solutions for traditional and emerging HPC and datacenter applications, including applications, programming models, and toolchains among others.
The topics of interest for this workshop include, but it is not constrained to the following:
Advances and future trends and challenges in FPGA/xPU accelerators for HPC and data center systems
Novel methods, tools, and programming models to enhance FPGA/xPU accelerator functionalities across HPC and datacenter systems
FPGA/xPU accelerator architecture design flow for HPC and data center
Programming environments for reconfigurable systems to increase the rate of productivity
Reconfigurable computing applications and/or efficient algorithms for reconfigurable hardware
Other topics related to FPGA/xPU accelerators, reconfigurable computing and HPC

10:15 - 11:00 Keynote by Carsten Binnig (TU Darmstadt): Databases on High-speed Networks: The Time for RDMA has come!
Abstract: High-speed networks that offer RDMA-like technologies have become the standard in data center networks for major cloud providers, providing efficient routing of massive application traffic at scale with low latency. With the recent pivot of the DBMS market from on-premise to cloud-based solutions, there is an opportune moment for system builders to adopt RDMA for constructing truly scalable cloud databases. In this talk, I will first introduce RDMA and its cloud-deployed derivatives, followed by an overview of the important insights gained over the past decade on effectively and correctly utilizing RDMA for designing scalable database systems. Finally, the talk will also cover recent opportunities and future directions such as programmability of the network on how to improve RDMA for databases in the cloud.

Alexander Krause (TU Dresden): Program your (custom) SIMD instruction set on FPGA in C++
Abstract: Field Programmable Gate Arrays (FPGAs) are more and more becoming a viable option for implementing data processing pipelines as their computing capacity as well as the access bandwidth between host and device memory continues to increase. Unfortunately, nowadays hardware description languages are still mainly used for programming FPGAs which implies major limitations. To tackle this issue, this talk shows that the general-purpose parallel processing architecture SIMD (Single Instruction Multiple Data) is a perfect match for FPGAs. With this specific architecture, we are able to consider an FPGA as SIMD processing unit and the necessary SIMD instruction set can now be implemented in C++. This offers a lot of advantages if both software (SIMDified query processing) and hardware can be written consistently in C++.

Marcus Paradies (TU Ilmenau): Leveraging Computational Storage for Data-Intensive Applications - Myth or Reality?
Abstract: Computational Storage refers to storage architectures that provide Computational Storage Functions coupled to storage, offloading host processing, or reducing data movement. Initial research demonstrators have shown that Computational Storage can achieve better performance and thereby consume less energy for certain data-intensive tasks compared to traditional data-shipping architectures.

In this presentation I will share my view of the current landscape of Computational Storage ranging from the storage hardware perspective up to applications that can benefit from Computational Storage. Finally I will share my view on how Computational Storage can fit into the overall system landscape and also highlight possible research directions.

Burkhard Ringlein (IBM Zürich): Don't forget the compiler: Why FPGAs for HPC need to look beyond circuits and applications
Abstract: FPGAs promise to accelerate HPC workloads and ML/AI models while also being energy efficient. However, today's FPGA tool chains are cumbersome to use, limited to specific use cases and devices, and mostly fail to support workflows requiring multi-node application scenarios. Within the H2020 project EVEREST (https://everest-h2020.eu/), we developed a design environment that aims to simplify the mapping of complex end-user workflows, like DNN inference or big data processing, to energy-optimized heterogeneous hardware with a focus on FPGA-accelerated systems. In this presentation, I will analyze the blind spots of the state of the art and introduce the practical solutions developed within the EVEREST project and the cloudFPGA team in Zurich. I will also present potential solutions for distributed HPC/ML applications and a prototype implementation, called DOSA (https://github.com/cloudFPGA/DOSA), that provides a one-click solution to partitioning, implementation and deployment of DNNs on multiple FPGAs.
