Optimizing the deployment of Deep Neural Networks (DNNs) is hard. Despite deep learning approaches increasingly providing state-of-the-art solutions to a variety of difficult problems, such as computer vision and natural language processing, DNNs can be prohibitively expensive, for example, in terms of inference time or memory usage. Effective exploration of the design space requires a […]

In recent years, the field of Deep Learning has seen many disruptive and impactful advancements. Given the increasing complexity of deep neural networks, the need for efficient hardware accelerators has become more and more pressing to design heterogeneous HPC platforms. The design of Deep Learning accelerators requires a multidisciplinary approach, combining expertise from several areas, […]

The increasing GPU performance and maturing computational platform make it possible to handle general-purpose computing jobs traditionally computed by the CPU. Also, just like what we did in the CPU program, we use testing to verify the correctness of the GPU program. However, the quality of the tests may remain unknown, which inspires us to […]

Iteration-based algorithms have been widely used and achieved excellent results in many fields. However, in the big data era, data that needs to be processed is enormous in terms of both depth (the dimensionality of data) and breadth (the volume of data). Due to the slowdown of Moore’s Law, the computing power of single-core CPUs […]

The proliferation of artificial intelligence applications has underscored the need for increased portability among graphic processing units (GPUs) from different vendors. With CUDA as one of the most popular GPU programming languages, CuPBoP (CUDA for Parallelized and Broad-range Processors) aims to provide NVIDIA’s proprietary CUDA language support to a variety of GPU and CPU platforms […]

Sparse matrix multiplication is an important kernel for large-scale graph processing and other data-intensive applications. In this paper, we implement various asynchronous, RDMA-based sparse times dense (SpMM) and sparse times sparse (SpGEMM) algorithms, evaluating their performance running in a distributed memory setting on GPUs. Our RDMA-based implementations use the NVSHMEM communication library for direct, asynchronous […]

All major weather and climate applications are currently developed using languages such as Fortran or C++. This is typical in the domain of high performance computing (HPC), where efficient execution is an important concern. Unfortunately, this approach leads to implementations that intermix optimizations for specific hardware architectures with the high-level numerical methods that are typical […]

A wide range of bioinformatics applications have to deal with a continuously growing amount of data generated by high-throughput sequencing techniques. Exclusively CPU-based workstations fail to keep up with the task. Instead of employing dozens of CPU cluster nodes to increase the computational power, massively parallel accelerators like modern CUDA-enabled GPUs can be used to […]

High performance computing is a topic that has risen to the top in the era of digitalization, AI and automation. Therefore, the search for more cost and time effective ways to implement HPC work is always a subject extensively researched. One part of this is to have hardware that is capable to improve on these […]
