Multi-agent reinforcement learning experiments and open-source training environments are typically limited in scale, supporting tens or sometimes up to hundreds of interacting agents. In this paper we demonstrate the use of Vogue, a high performance agent based model (ABM) framework. Vogue serves as a multi-agent training environment, supporting thousands to tens of thousands of interacting […]

In a wide range of applications, convolutional neural networks (CNNs) have been widely used, including face and speech recognition, picture retrieval and classification, and automated driving. As a result, CNN accelerators have become a popular topic of discourse. CNN Accelerators Graphics processing units (GPU) are often employed in CNN accelerators, and they are referred to […]

Recurrent neural networks have been shown to be effective architectures for many tasks in high energy physics, and thus have been widely adopted. Their use in low-latency environments has, however, been limited as a result of the difficulties of implementing recurrent architectures on field-programmable gate arrays (FPGAs). In this paper we present an implementation of […]

While parallelism remains the main source of performance, architectural implementations and programming models change with each new hardware generation, often leading to costly application re-engineering. Most tools for performance portability require manual and costly application porting to yet another programming model. We propose an alternative approach that automatically translates programs written in one programming model […]

Privacy and security-related concerns are growing as machine learning reaches diverse application domains. The data holders want to train or infer with private data while exploiting accelerators, such as GPUs, that are hosted in the cloud. Cloud systems are vulnerable to attackers that compromise the privacy of data and integrity of computations. Tackling such a […]

This dissertation is primarily presenting the design of Digital Signal Processing (DSP) between the transmission in Bluetooth Low Energy Physical Layer (BLE PHY), and its implementation in a Field Programmable Gate Array (FPGA) device with Open Computing Language (OpenCL). During the design of DSP, it bases on the In-Phase/Quadrature-Phase (IQ) architecture to construct the modulation […]

In recent years, approaches that seek to extract valuable information from large datasets have become particularly relevant in today’s society. In this category, we can highlight those problems that comprise data analysis distributed across two-dimensional scenarios called spatial problems. These usually involve processing (i) a series of features distributed across a given plane or (ii) […]

The Intel DPC++ Compatibility Tool is a component of the Intel oneAPI Base Toolkit. This tool automatically transforms CUDA code into Data Parallel C++ (DPC++), thus assisting in the migration process. DPC++ is an implementation of the programming standard for heterogeneous computing known as SYCL, which unifies the development of parallel applications on CPUs, GPUs […]

Nowadays, High-performance Computing (HPC) scientific applications often face performance challenges when running on heterogeneous supercomputers, so do scalability, portability, and efficiency issues. For years, supercomputer architectures have been rapidly changing and becoming more complex, and this challenge will become even more complicated as we enter the exascale era, where computers will exceed one quintillion calculations […]

Tensors, which generalize matrices to more than two dimensions, are fundamental to many disciplines, such as scientific computing and machine learning. Improving the performance and scalability of tensor computation is essential to those domains. The recent advance of heterogeneous memory is promising to deliver large-scale, high-performance tensor computation. However, it is challenging to leverage memory […]

This paper presents a novel nearest neighbor search algorithm achieving TPU (Google Tensor Processing Unit) peak performance, outperforming state-of-the-art GPU algorithms with similar level of recall. The design of the proposed algorithm is motivated by an accurate accelerator performance model that takes into account both the memory and instruction bottlenecks. Our algorithm comes with an […]

These days, it is typical for a large-scale cluster system to have different kinds of GPUs. However, HPL (High-Performance LINPACK), the de-facto standard LINPACK implementation for evaluating the performance of a cluster system, is originally designed to work only for homogeneous CPU-only systems. In this paper, we develop SnuHPL, an optimized HPL for clusters of […]
