A Highly Parallel Semi-Dataflow FPGA Architecture for Large-Scale N-Body Simu...NECST Lab @ Politecnico di Milano
This document proposes a highly parallel semi-dataflow FPGA architecture for accelerating large-scale N-body simulations. The key aspects of the proposed design are: 1) A hardware/software partitioning that accelerates the computationally intensive force calculation step on the FPGA; 2) An optimized data transfer approach to reduce memory traffic; 3) A semi-dataflow architecture providing high parallelism through 48 computation pipelines; and 4) A tiling approach to further improve performance and resource utilization. Experimental results show the design achieves up to 4400 million particle-pairs per second, outperforming CPU and GPU implementations in terms of performance and performance-per-watt.Real-time and long-time together

CNIT 127 Ch 5: Introduction to heap overflows
This document discusses heap overflows and exploit development. It explains that the heap is an area of memory used to dynamically allocate data at runtime using functions like malloc() and free(). While the stack stores return addresses that can be controlled in a buffer overflow, the heap does not directly store EIP. However, it contains pointers that are written to when freeing memory chunks, which can be exploited if a chunk overflow is used to control those writes and modify arbitrary memory locations. Potential targets include return addresses on the stack, the global offset table, destructors table, and function pointers.

This document summarizes an approach called Gossip-based Resource Allocation for Green Computing in Large Clouds. The approach uses a distributed middleware architecture and gossip-based algorithms to dynamically consolidate virtual machines on the minimum number of active servers for energy efficiency. It aims to maximize utility and minimize power consumption and reconfiguration costs in large cloud environments with over 100,000 machines. The Generic Resource Management Protocol (GRMP) is presented as a scalable solution that can be instantiated in different ways, such as GRMP-Q, to achieve server consolidation under low load and fair allocation under high load. Simulation results show GRMP-Q reduces power consumption while maintaining satisfied demand and fairness across large systems.

Towards Utilizing GPUs in Information Visualization
The document proposes GPUVis, a model and implementation for utilizing GPUs in information visualization. GPUVis defines image-space operations (IVOs) that transform data tuples into colored pixels. IVOs can perform tasks like color mapping, glyph rendering, filtering, and statistical analysis. GPUVis implements IVOs as shader programs and provides a visual editor to compose IVOs without programming. A demo of GPUVis shows performance gains over OpenGL for visualizations like scatter plots, node-link diagrams, and treemaps. Future work aims to improve control flow, optimization, and transition to CUDA/OpenCL.
Histogram Equalized Heat Maps from Log Data via Apache Spark with Arvind Rao
Reverse geocoding is one of HERE Technologies most heavily used services. From its access logs geocodes can be extracted and then counted with respect to some cellulation of the earth–-creating a sparse heat map. For our Place & Address Search products we use such a heat map to define a notion of relative place importance to rank and index addresses and places. However, the large data size, sparsity, and variations in traffic from which different global heat maps may be derived, makes faithful visualization and comparison a challenge. Additionally, common implementations of spatial image processing techniques that can help address the aforementioned challenges don’t map directly onto Spark’s computing engine.
In this talk Arvind Rao will describe implementations of histogram equalization and kernel-based sparse image processing methods on Spark. Histogram equalization, which is best known as a method of contrast enhancement, automatically normalizes images, facilitating comparison. Along the way, Arvind will talk about how HERE uses heat maps as a feature in their autocompletion service, and say just enough about perception of contrast to put histogram equalization in context.

This document presents a GPU-accelerated algorithm for solving the Group Steiner Problem (GSP) which arises in routing phases of VLSI circuit design. The algorithm uses a depth-bounded heuristic to construct approximate minimum-cost Steiner trees in parallel using CUDA-aware MPI. Evaluation on a supercomputer shows the parallel implementation achieves up to 302x speedup over serial algorithms and scales well with problem size and processor count.

This document describes a 3-round MapReduce algorithm for finding small dense subgraphs within a large graph. In Round 1, it computes the graph density by counting edges and nodes. Round 2 partitions the graph and prunes edges with degrees lower than the density. Round 3 iteratively removes the lowest degree node to find the smallest subgraph. The algorithm was tested on real graphs and found optimal solutions with runtimes of minutes or less depending on the graph size and pruning threshold.

Image Segmentation Chain
In miscellaneous applications of image treatment, thinning and crest restoring present a lot of interests. Recommended algorithms for these procedures are those able to act directly over greyscales images while preserving topology. But their strong consummation in term of time remains the major disadvantage in their choice. In this paper we present an efficient hardware implementation on RISC processor of two powerful algorithms of thinning and crest restoring developed by our team. Proposed implementation enhances execution time. A chain of segmentation applied to medical imaging will serve as a concrete example to illustrate the improvements brought thanks to the optimization techniques in both algorithm and architectural levels. The particular use of the SSE instruction set relative to the X86_32 processors (PIV 3.06 GHz) will allow a best performance for real time processing: a cadency of 33 images (512*512) per second is assure
Joint CSI Estimation, Beamforming and Scheduling Design for Wideband Massive ...
The document presents a new design for joint channel estimation, beamforming, and scheduling for wideband massive MIMO systems. It proposes using non-orthogonal pilots for channel estimation and a two-phase scheduling approach. Simulation results show the proposed design achieves higher total rates than conventional OFDM and performs better in dense multipath environments, especially with larger bandwidths and antenna arrays. An open issue discussed is comparing the proposed non-orthogonal pilot scheme to non-orthogonal multiple access techniques.
Harnessing OpenCL in Modern Coprocessors
Talk @ APT Group, University of Manchester, 06 August 2014
Abstract:
Nowadays HPC systems, such as those in the Top500, are equipped with a range of different processors, from multi-core CPUs to GPUs. Programming them can be a tough job, specially if we want to squeeze every last FLOPs of performance out of them.
As a Phd Student, I am now doing a brief research visit in the APT group, working in topics related to the programmability and efficient use of GPUs and many-core coprocessors. In particular, I am implementing a large database operation using OpenCL in these state-of-the-art systems. In this talk I will summarize my work in Manchester and discuss the future work in this topic.
Heap
This document discusses heaps and their implementation and applications. It defines a heap as a complete binary tree where each node's value is greater than its children in a max heap or less than its children in a min heap. Heaps can be implemented using an array, where calculations allow accessing a node's children and parent. Common heap operations like insertion and deletion take O(log n) time. Heaps are used in priority queues, sorting algorithms like heapsort, and some graph algorithms. Heapsort first builds a max or min heap from an array then repeatedly deletes the root to sort in descending or ascending order respectively.

While Obama’s new clean power plan is certainly very well-intentioned, it implicitly throws the fossil fuel industry “under the bus,” naively assumes that wind and solar power will take up the slack at reasonable cost, and does not really attempt to develop radical new sources of low-cost energy.
Rather than eventually replacing fossil fuels with solar, wind, and renewable energy sources over time, LENR technology instead enables oil, gas, and coal producers to convert fossil fuels into cleaner, more valuable form of CO2-free LENR energy --- energy producers, energy consumers, and Mother Earth all win.
While solar PV and wind are CO2-free and extremely biosafe, their intrinsic energy densities are much lower than today’s fossil fuels and inherently intermittent --- not continuous --- sources of electrical and thermal power. Solar and wind renewables therefore simply cannot 100% replace fossil energy sources without enormous economic disruption and gigantic increases in energy costs.
LENRs are the only primary energy technology on foreseeable horizon that could provide the world with affordable dense green energy, connect the unconnected, and empower billions of now powerless, energy-poor people
Lattice’s strategy for replacing today’s combustion with LENR transmutation of Carbon saves the fossil fuel industry yet is highly synergistic with renewables, enables sustainable economic growth, and helps to ameliorate CO2-driven climate change.

Optimization of Continuous Queries in Federated Database and Stream Processin...
The constantly increasing number of connected devices and sensors results in increasing volume and velocity of sensor-based streaming data. Traditional approaches for processing high velocity sensor data rely on stream processing engines. However, the increasing complexity of continuous queries executed on top of high velocity data has resulted in growing demand for federated systems composed of data stream processing engines and database engines. One of major challenges for such systems is to devise the optimal query execution plan to maximize the throughput of continuous queries.
In this paper we present a general framework for federated database and stream processing systems, and introduce the design and implementation of a cost-based optimizer for optimizing relational continuous queries in such systems. Our optimizer uses characteristics of continuous queries and source data streams to devise an optimal placement for each operator of a continuous query. This fine level of optimization, combined with the estimation of the feasibility of query plans, allows our optimizer to devise query plans which result in 8 times higher throughput as compared to the baseline approach which uses only stream processing engines. Moreover, our experimental results showed that even for simple queries, a hybrid execution plan can result in 4 times and 1.6 times higher throughput than a pure stream processing engine plan and a pure database engine plan, respectively.

Swift Parallel Scripting for High-Performance Workflow
The Swift scripting language was created to provide a simple, compact way to write parallel scripts that run many copies of ordinary programs concurrently in various workflow patterns, reducing the need for complex parallel programming or arcane scripting to achieve this common high-level task. The result was a highly portable programming model based on implicitly parallel functional dataflow. The same Swift script runs on multi-core computers, clusters, grids, clouds, and supercomputers, and is thus a useful tool for moving workflow computations from laptop to distributed and/or high performance systems.
Swift has proven to be very general, and is in use in domains ranging from earth systems to bioinformatics to molecular modeling. It’s more recently been adapted to serve as a programming model for much finer-grain in-memory workflow on extreme scale systems, where it can perform task rates in the millions to billion-per-second.
In this talk, we describe the state of Swift’s implementation, present several Swift applications, and discuss ideas for of the future evolution of the programming model on which it’s based.

Spark Streaming and IoT by Mike Freedman
This document discusses using Spark Streaming for IoT applications and the challenges involved. It notes that while Spark simplifies programming across different processing intervals from batch to stream, programming models alone are not sufficient as IoT data streams can have varying rates and delays. It proposes a unified data infrastructure with abstractions like data series that support joining real-time and historical data while handling delays transparently. It also suggests approaches for Spark Streaming to better support processing many independent low-volume IoT streams concurrently and improving resource utilization for such applications. Finally, it introduces the Device-Model-Infra framework for addressing these IoT analytics challenges through combined programming models and data abstractions.

Giuseppe will present the differences between high-performance and high-throughput applications. High-throughput computing (HTC) refers to computations where individual tasks do not need to interact while running. It differs from High-performance (HPC) where frequent and rapid exchanges of intermediate results is required to perform the computations. HPC codes are based on tightly coupled MPI, OpenMP, GPGPU, and hybrid programs and require low latency interconnected nodes. HTC makes use of unreliable components distributing the work out to every node and collecting results at the end of all parallel tasks.

Coding the Continuum
In 2001, as early high-speed networks were deployed, George Gilder observed that “when the network is as fast as the computer's internal links, the machine disintegrates across the net into a set of special purpose appliances.” Two decades later, our networks are 1,000 times faster, our appliances are increasingly specialized, and our computer systems are indeed disintegrating. As hardware acceleration overcomes speed-of-light delays, time and space merge into a computing continuum. Familiar questions like “where should I compute,” “for what workloads should I design computers,” and "where should I place my computers” seem to allow for a myriad of new answers that are exhilarating but also daunting. Are there concepts that can help guide us as we design applications and computer systems in a world that is untethered from familiar landmarks like center, cloud, edge? I propose some ideas and report on experiments in coding the continuum.

As the data and models scale, it becomes necessary to have multiple processing units for both training and inference. SignSGD is a gradient compression algorithm that only transmits the sign of the stochastic gradients during distributed training. This algorithm uses 32 times less communication per iteration than distributed SGD. We show that signSGD obtains free lunch both in theory and practice: no loss in accuracy while yielding speedups. Pushing the current boundaries of deep learning also requires using multiple dimensions and modalities. These can be encoded into tensors, which are natural extensions of matrices. These functionalities are available in the Tensorly package with multiple backend interfaces for large-scale deep learning.

The CAOS framework: democratize the acceleration of compute intensive applica...NECST Lab @ Politecnico di Milano
The increasing demand for computing power in fields such as biology, finance, machine learning is pushing the adoption of reconfigurable hardware in order to keep up with the required performance level at a sustainable power consumption. Within this context, FPGA devices represent an interesting solution as they combine the benefits of power efficiency, performance and flexibility. Nevertheless, the steep learning curve and experience needed to develop efficient FPGA-based systems represents one of the main limiting factor for a broad utilization of such devices.
In this talk, we present CAOS, a framework which helps the application designer in identifying acceleration opportunities and guides through the implementation of the final FPGA-based system. The CAOS platform targets the full stack of the application optimization process, starting from the identification of the kernel functions to accelerate, to the optimization of such kernels and to the generation of the runtime management and the configuration files needed to program the FPGA.Review on Multiply-Accumulate Unit
In present day MAC unit is demanded in most of the Digital signal processing. Function of addition and multiplication is performed by the MAC unit. MAC operates in two stages. Firstly, multiplier computes the given number output and the result is forwarded to second stage i.e. addition/accumulation operates. Speed of multiplier is important in MAC unit which determines critical path as well as area is also of great importance in designing of MAC unit. Multiplier plays an important roles in many digital signal processing (DSP) applications such as in convolution, digital filters and other data processing unit. Many research has been performed on MAC implementation. This paper provides analysis of the research and investigations held till now.

This document proposes an adaptive and auto-scaling stream processor called Wisdom to enable real-time intrusion detection in network traffic. Wisdom can dynamically optimize complex event processing (CEP) rules using hybrid optimization algorithms like particle swarm optimization and bisection. Tests show Wisdom can detect attacks like HTTP slow header denial of service and port scans with over 99.95% accuracy. Wisdom also allows functionally auto-scaling deployments of CEP rules to optimize resource usage.
FPGA based Efficient Interpolator design using DALUT Algorithm
The document describes the design and implementation of an efficient interpolator for wireless communication systems using FPGA. It proposes a multiplier-less technique using distributed arithmetic look-up tables (DALUT) that replaces multiply-accumulate operations with LUT accesses. A 66th-order half-band polyphase FIR structure is implemented using the DALUT approach on Spartan-3E and Virtex2Pro FPGAs. Results show the proposed design achieves maximum frequencies of 92.859MHz on Virtex Pro and 61.6MHz on Spartan 3E while consuming fewer resources than a traditional MAC-based design.
FPGA based Efficient Interpolator design using DALUT Algorithm
Interpolator is an important sampling device used for multirate filtering to
provide signal processing in wireless communication system. There are many
applications in which sampling rate must be changed. Interpolators and decimators are
utilized to increase or decrease the sampling rate. In this paper an efficient method has
been presented to implement high speed and area efficient interpolator for wireless
communication systems. A multiplier less technique is used which substitutes multiplyand-accumulate
operations with look up table (LUT) accesses. Interpolator has been
implemented using Partitioned distributed arithmetic look up table (DALUT)
technique. This technique has been used to take an optimal advantage of embedded
LUTs of the target FPGA. This method is useful to enhance the system performance in
terms of speed and area. The proposed interpolator has been designed using half band
poly phase FIR structure with Matlab, simulated with ISE, synthesized with Xilinx
Synthesis Tools (XST) and implemented on Spartan-3E and Virtex2pro device. The
proposed LUT based multiplier less approach has shown a maximum operating
frequency of 92.859 MHz with Virtex Pro and 61.6 MHz with Spartan 3E by
consuming considerably less resources to provide cost effective solution for wireless
communication systems.
