Deep neuralnetworks (DNNs) have been widely applied in the field of artificial intelligence, e.g., natural language processing, computer vision, etc. Researchers and industry practitioners typically use GPU to train complex hundred-layers deep networks. However, as the networks going wider and deeper, the limited GPU memory becomes a significant bottleneck, restricting the size of networks to be trained. In the training of DNNs, the intermediate layer outputs are the major contributors to the memory footprint. Offloading and prefetching feature maps is one of the crucial techniques to overcome the GPU memory shortage by utilizing the CPU DRAM as an external buffer for the GPU. However, we find that the layer-by-layer asynchronous approach cannot be effectively applied to the overlap between communication and computation, particularly for nonlinear networks. Furthermore, the default memory management policy could cause high GPU memory fragmentation for the networks with complex nonlinearities. Based on these observations, we adopt an efficient graph analysis and exploit the layered dependency structures to improve the overlap ratio. To achieve minimal memory fragmentation, we design a Group Tensors By Mobility (GTBM) placement policy to allocate tensors on the proposed unified memory pool for data structures with varied data sizes and dynamic dependencies. We implement and evaluate our system, Dymem, on several linear and nonlinear networks. Compared with vDNN and SuperNeurons, our proposed approach can achieve memory cost reduction by up to 31%. The dependency-aware strategy can improve the end-to-end throughput for nonlinear networks by up to 42%.

With the growing performance and wide application of deep neuralnetworks (DNNs), recent years have seen enormous efforts on DNN accelerator hardware design for platforms from mobile devices to data centers. The systolic array has been a popular architectural choice for many proposed DNN accelerators with hundreds to thousands of processing elements (PEs) for parallel computing. Systolic array-based DNN accelerators for datacenter applications have high power consumption and non-uniform workload distribution, which makes power delivery network (PDN) design challenging. Server-class multicore processors have benefited from distributed on-chip voltage regulation and heterogeneous voltage regulation (HVR) for improving energy efficiency while guaranteeing power delivery integrity. This paper presents the first work on HVR-based PDN architecture and control for systolic array-based DNN accelerators. We propose to employ a PDN architecture comprising heterogeneous on-chip and off-chip voltage regulators and multiple power domains. By analyzing patterns of typical DNN workloads via a modeling framework, we propose a DNN workload-aware dynamic PDN control policy to maximize system energy efficiency while ensuring power integrity. We demonstrate significant energy efficiency improvements brought by the proposed PDN architecture, dynamic control, and power gating, which lead to a more than five-fold reduction of leakage energy and PDN energy overhead for systolic array DNN accelerators.

The representation of DNA sequences has been an interesting topic of discussion for many years. Presently, given the usefulness of representations built upon embeddings for Natural Language processing (NLP), there have been efforts to transfer such paradigms to the DNA world and related problems. In this paper, we study different DNA representations on the well-studied problem of Conserved Non-coding Elements (CNEs), trying to understand how well existing representations utilize the value of context, both in terms of local, near context, but also of long-distance interactions in genomic sequences. To this end, we apply a number of methods, including probabilistic models (LDA) and hybrid probabilistic-neural models (lda2vec) on appropriate datasets, compare the results to pre-existing methods and discuss the findings to better understand the value and challenges of different representations in the given domain.

Voltage sag characteristics are subject to change owing to system short-circuit rating in situations where DG’s contribution to power injection during fault events is considered. Therefore, the fast growth in the deployment of DG leads to an analysis of its impact on system operation and reliability. A methodology for characterization and identification of voltage sags and swells caused by faults in a distribution system with distributed generation (DG) is presented in this paper. The proposed methodology, involving Wavelet transform processing technique and a neuralnetwork classifier, yields a computational tool applied to IEEE 13-Node Test Feeder. This methodology provides a way to handle high data stream to obtain a power system response generalization to voltage disturbances.
