Title: Towards the Quantum Internet: Building an entanglement-sharing quantum network
Abstract: The goal of quantum communication is to transmit quantum states between distant sites. The key aspect to achieve this goal is the generation entangled states over long distances. Such states can then be used to faithfully transfer classical and quantum states via quantum teleportation. This is an exciting new direction which establishes the fundamentals of a new quantum internet. The big challenge, however, is that the entanglement generated between two distant sites decreases exponentially with the length of the connecting channel. To overcome this difficulty, the new concepts of entanglement swapping, and quantum repeater operation are needed.
In this talk we will show our progress towards building a quantum network of many quantum devices capable of distributing entanglement over long distances connecting Stony Brook University and the Brookhaven National Laboratory in Long Island, New York. We will show how to produce photonic quantum entanglement in the laboratory and how to store it and distribute it by optically manipulating the properties of room temperature atomic clouds. Finally, we will discuss our recent experiments in which several quantum devices are already interconnected forming elementary quantum cryptographic and quantum repeater networks. Finally, we will discuss how these milestones can form the backbone of a future quantum-information-enhanced internet.

Title: MDGRAPE-4A: A Special-purpose computer system for Molecular Dynamics simulations
Abstract: We have developed several special-purpose computer systems for particle simulations called “GRAPE (GRAvity PipE)”. The GRAPE systems are dedicated or quasi-general-purpose accelerators attached to host computers. The efficient parallelization in GRAPE systems provided us high-performance at low cost and low energy. However, as the performance increases, it requires a more powerful host machine – a PC cluster. Thus, the bottleneck in strong scaling lies in host systems, not in accelerators. This is often the case for GPU cluster systems. To overcome the bottleneck, we are currently developing the “MDGRAPE-4”, the special-purpose computer system for molecular dynamics (MD) simulations. The MDGRAPE-4 has similar structure with Anton by D. E. Shaw Research. It consists of System-on-Chip LSIs with general-purpose cores, dedicated pipelines, network interfaces, and memory units. By the integration of these elements we aim to achieve a simulation speed of a few ten microsecond per step by its low latency memory access and networking.

Title: Tomorrow’s Supercomputers, Yesterday’s Practices: Applications of cloud-backed large system emulation for supercomputer software development
Abstract: Software development for supercomputers has been flawed since the early days of supercomputing. Typically, a programmer user develops their software on their workstation and then submits it to a debug queue for testing. Waiting for the test job to run in the debug queue often proves futile, as the run may not provide any information useful in debugging or troubleshooting.
This approach has many shortcomings:
- The development workstation and the target supercomputer are two entirely different machines, at best they may have the same processor architecture.
- There is no network communication during computation in a workstation environment, only socket-to-socket, at best
- The debug queue is around 10% of the entire system resources, what if the target deployment requires 25% of the target system?
- Debuggers are often licensed on a per-node basis, making debugging in a large environment prohibitively expensive and incompatible with cloud.
Supercomputers are expensive and, by design, are meant to run production codes. It makes more sense to run development, testing, and validation workloads in the cloud.

Title: Emergent Atomic Switch Networks for Neuroarchitectonics:
Abstract: Artificial realizations of the mammalian brain alongside their integration into electronic components are explored through neuromorphic
architectures, neuroarchitectonics, on CMOS compatible platforms. Exploration of neuromorphic technologies continue to develop as an alternative computational paradigm as both capacity and capability reach their fundamental limits with the end of the transistor-driven industrial phenomenon of Moore’s law. Here, we consider the electronic landscape within neuromorphic technologies and the role of the atomic switch as a model device. We report the fabrication of an atomic switch network (ASN) showing critical dynamics and harness criticality to perform benchmark signal classification and Boolean logic tasks. Observed evidence of biomimetic behavior such as synaptic plasticity and fading memory enable the ASN to attain a cognitive capability within the context of artificial neural networks. Single atomic switches have been shown to exhibit both long-term and short-term memorization based on their history of excitation dynamics. When connected together in a massively dense network using nanoarchitectonics they additionally display emergent behavior observable using multielectrode arrays similar to EEG to follow their spatio-temporal dynamics. A number of architectures such as Reservoir computation (RC) are promising methods to implement neuromorphics.

Title: Technology of Real-World Analyzers (TAUR) and its practical application
Abstract: As a result of many years of research and testing, at Lodz University of Technology the concept of technology of Real-World Analyzers (in polish: Technologia Analizatorów Układów Rzeczywistych TAUR) was developed . Devices built in this technology can contain up to several hundred million operational cells placed in 3D face centered cubic (fcc) network nodes. These machines are a fully parallel data processing systems equipped with low-latency communication channels, designed for simulations of huge amount of relatively simple elements working in parallel and interacting locally. Devices can support solving problems from various fields of science and technology such as e.g. molecular simulations, artificial intelligence or data encryption.
In frame of TAUR technology the device called Analyzer of Real Complex Systems (in polish: Analizator Rzeczywistych Układów Złożonych – ARUZ) was designed and constructed . This machine is located in Poland in the city of Łódź in BioNanoPark. ARUZ is based on 26 000 reconfigurable FPGA devices (Field Programmable Gate Array) connected in 3D fcc network and working as signal processing units.
Currently, ARUZ is intensively used to analyze computationally demanding complex macromolecular systems. Simulation of soft matter systems in chemistry and polymer physics (e.g. polymer liquids containing brushes, bottle-brushes, polymer stars and networks) is pretty challenging because must involve a variety of time scales and broad range of sizes – from Fickian–like dynamics to segmental motion of chains and mass-center diffusion. An unique simulation method in this field, called Dynamic Lattice Liquid (DLL) model, was proposed by Tadeusz Pakula . The DLL correctly represents the dynamics of the studied molecular structure, taking into account the diffusion restrictions associated with obstacles occurring in the system. The DLL algorithm was implemented in ARUZ allowing to study the dynamics of molecular systems on the time scale difficult to access (or unreachable in some cases) for existing computing systems.

Title: The Data-Model Convergence: a case for Software Defined Architectures
Abstract: High Performance Computing, data analytics, and machine learning are often considered three separate and different approaches. Applications, software and now hardware stacks are typically designed to only address one of the areas at a time. This creates a false distinction across the three different areas. In reality, domain scientists need to exercise all the three approaches in an integrated way. For example, large scale simulations generate enormous amount of data, to which Big Data Analytics techniques can be applied. Or, as scientist seek to use data analytics as well as simulation for discovery, machine learning can play an important role in making sense of the disparate source’s information. Pacific Northwest National Laboratory is launching a new Laboratory Directed Research and Development (LDRD) Initiative to investigate the integration of the three techniques at all level of the high-performance computing stack, the Data-Model Convergence (DMC) Initiative. The DMC Initiative aims to increase scientist productivity by enabling purpose-built software and hardware and domain-aware ML techniques.
In this talk, I will present the objectives of PNNL’s DMC Initiative, highlighting the research that will be performed to enable the integration of vastly different programming paradigms and mental models. I will then make the case for how reconfigurable architectures could represent a great opportunity to address the challenges of DMC. In principle, the possibility to dynamically modify the architecture during runtime could provide a way to address the requirement of workloads that have significantly diverse behaviors across phases, without losing too much flexibility or programmer productivity, with respect to highly heterogeneous architectures composed by sea of fixed application specific accelerators. Reconfigurable architectures have been explored since long time ago, and arguably new software breakthroughs are required to make them successful. I will thus present the efforts that the DMC initiative is launching to design a productive toolchain for upcoming novel reconfigurable systems. I will then proceed to discuss the influences and relations of the DMC initiative with other projects ongoing at PNNL that are exploring methods to accelerate, through custom hardware/software stacks and advanced design automation approaches, machine learning and data analytics.

Title: Graphic Encoding of Macromolecules for Quantitative Classification of Protein Structure and Representation of Conformational Changes
Abstract: The function of a protein depends on its three-dimensional structure. Computational approaches for protein function prediction, and more generally macromolecular analysis are limited by the expressiveness and complexity of protein representation formats. Partial structural representations and representations that rely on homology alignments are both computationally expensive and do not scale with the number of molecules, as three-dimensional matching is an NP-hard problem. Being able to represent heterogeneous macromolecules in a homogeneous, easy-to-compare, and easy-to-analyze format has the potential to disrupt the way and scale at which molecular analysis is done today. This talk introduces a generalizable and homogeneous representation of macromolecules that explicitly encodes tertiary structural motifs and their relative distance as a proxy of their interaction. The final goal of this encoding is to expose intra- and inter-molecular structural patterns in a scalable way, i.e., that does not require performing alignments, homology calculations, or other expensive operations between pairs, or sets, of proteins. To demonstrate the effectiveness of this encoding, we also present an image processing system based on deep convolutional neural networks that is able to use our graphic representation to perform high throughput protein function prediction and interpretation of protein folding.

Title: A Data-Centric Approach to Extreme-Scale Ab initio Dissipative Quantum Transport Simulations
Abstract: The computational efficiency of a state of the art ab initio quantum transport (QT) solver, capable of revealing the coupled electro-thermal properties of atomically-resolved nano-transistors, has been improved by up to two orders of magnitude through a data centric reorganization of the application. The approach yields coarse-and fine-grained data-movement characteristics that can be used for performance and communication modeling, communication-avoidance, and dataflow transformations. The resulting code has been tuned for two top-6 hybrid supercomputers, reaching a sustained performance of 85.45 Pflop/s on 4,560 nodes of Summit (42.55% of the peak) in double precision, and 90.89 Pflop/s in mixed precision. These computational achievements enable the restructured QT simulator to treat realistic nanoelectronic devices made of more than 10,000 atoms within a 14× shorter duration than the original code needs to handle a system with 1,000 atoms, on the same number of CPUs/GPUs and with the same physical accuracy.

Title: High Performance Services for genetic research
Abstract: Recent progress in genetic research was possible thanks to the progress in the experimental techniques. However such progress will not be possible without computational methods developed in the last decades. One of the milestones is BLAST (Basic Local Alignment Search Tool) – an essential algorithm that researchers use for sequence alignment analysis. Amongst different implementations of the BLAST algorithm, the NCBI-BLAST is the most popular. It can run on a single multithreading node. However, the volume of nucleotide and protein data is fast-growing, making single node insufficient. Therefore it is more and more important to develop high-performance computing solutions, which could help researchers to analyze genetic data in a fast and scalable way. In this lecture, we will present the execution of the BLAST algorithm on HPC clusters and supercomputers in a massively parallel manner using thousands of processors. The PCJ (Parallel Computing in Java) library has been used to implement the optimal splitting up of the input queries, work distribution and search management. It is used with the non-modified NCBI-BLAST package which is an additional advantage for the users. The result application PCJ-BLAST is responsible for the reading sequence for comparison, splitting it up and starting multiple NCBI-BLAST executables. Since I/O performance could limit sequence analysis performance we will also address this problem. Part of the talk will be dedicated to the PCJ which is key technology enabling efficient parallelization of the BLAST and other algorithms. We will present a general idea of the library as a parallelization tool in the PGAS paradigm as well as implementation details. Examples of successful parallelization of different algorithms from HPC, BigData and AI application domains will be provided. We will show that using Java and PCJ library it is possible to perform sequence analysis using hundreds of nodes in parallel. Since genomics research is getting significant attention in Europe we will present the Human Exposome Assessment Platform (HEAP) which is Horizon 2020 project starting 1st January 2020. It will create a global research resource that enables ethical and efficient management and processing of massive data from geographically distributed large-scale population cohorts. Also, a standardized, integrated and generic informatics platform will be created, It will provide PCJ-BLAST and other highly scalable genetics applications to the wide research community.

Title: Functional dynamics of biomolecules with supercomputers
Abstract: Proper association and recognition of biomolecules determines many life-sustaining processes occurring in a crowded environment of cells. In addition, biomolecules are intrinsically flexible and their dynamics is related to function. For example, flexibility of the ribosome, a protein synthesis molecular machine, is crucial for the fidelity of this synthesis in cells. Thus, not surprisingly, aminoglycoside antibiotics that affect bacterial protein synthesis hinder the functional flexibility of the ribosome. Therefore, understanding the dynamics of biomolecular recognition is indispensable in any drug design process. Binding of drugs to their intracellular targets requires conformational rearrangements of both binding partners in order to form a tight complex and inhibit the function of the target. Transport of drugs through cellular membranes is also a highly dynamic process.
I will talk about the importance of investigating biomolecular flexibility in drug design and transport. Using HPC resources we apply various molecular modeling methods and molecular dynamics simulations to investigate the processes of diffusion and flexibility of biomolecules. I will show examples of biological systems whose dynamics modulates their function and is crucial for drug design.

Title: Fast and Accurate Multiscale Modeling of Platelets Guided by Machine Learning
Abstract: Multiscale modeling in biomedical engineering is gaining momentum because of progress in supercomputing, applied mathematics, and quantitative biomedical engineering. For example, scientists in various disciplines have been advancing, slowly but steadily, the simulation of blood including its flowing and the physiological properties of such components as red blood cells, white blood cells, and platelets. Platelet activation and aggregation stimulate blood clotting that results in heart attacks and strokes causing nearly 20 million deaths each year. To reduce such deaths, we must discover new drugs. To discover new drugs, we must understand the mechanism of platelet activation and aggregation. To model platelets’ dynamics involves setting the basic space and time discretization in huge ranges of 5-6 orders of magnitudes, resulting from the relevant fundamental interactions at atomic, to molecular, to cell, to fluid scales. To achieve the desired accuracy at the minimal computational costs, we must select the correct physiological parameters in the force fields as well as the spatial and temporal discretization, by machine learning. We demonstrate our results of speeding up a multiscale platelet aggregation simulation, while maintaining desired accuracies, by orders of magnitude, compared with traditional algorithm that uses the smallest of temporal and spatial scales in order to capture the finest details of the dynamics. We present our analyses of the accuracies and efficiencies of the representative modeling. We will also outline the general methodologies of multiscale modeling of cells at atomic resolutions guided by machine learning.

Title: Towards Exascale Hyperbolic PDE Engines – Are We Skating to Where the Puck Will Be?
Abstract: Exascale supercomputers are “ante portas”. They pose novel challenges to simulation software, such as how to cope with heterogeneous performance of compute resources, increased failure rates and respective demands on resiliency, or with scalability on multiple levels of parallelism, which are at the same time suffering from unpredictable performance. CPU/GPU power will continue to outperform memory and communication hardware, which asks for algorithms that feature high arithmetic intensity and minimize data movement across the entire memory hierarchy. Can we successfully develop simulation software that will run efficiently on the supercomputers of 2030?
This talk will present on recent work to better prepare simulation software for exascale, focusing on two concrete packages: ExaHyPE and SeisSol. ExaHyPE is an engine to solve hyperbolic PDE systems. While it provides flexibility with respect to the tackled PDEs, it focuses on high-order discontinuous Galerkin (with a-posteriori Finite-Volume-based limiting) on tree-structure Cartesian meshes as the underlying numerical scheme. I will outline ExaHyPE’s code generation approach to tailor the engine to different needs of application, algorithm and code optimisation experts, and will highlight a fine-grain task-offloading strategy which can respond to performance fluctuations in hardware and combines with an MPI rank replication approach. Similar, I will present recent work on the earthquake simulation package SeisSol. SeisSol allows several modelling variants for seismic wave propagation and earthquake sourcing. It relies on code generation for its performance critical element-local small tensor operations, to cope with the complexity of realising several model variants on different hardware.

Title: Utility of Real time portable genome sequencing and HPC for global food security
Abstract: Portable DNA sequencing technology has great potential to reduce the risk of community crop failure and help improve livelihoods of millions of people, especially in low resourced communities. Crop losses due to plant viral diseases and pests are major constraints on food security and income for millions of households in sub-Saharan Africa (SSA). Such losses can be reduced if plant diseases and pests are correctly diagnosed and identified early. Currently, accurate diagnosis for definitive identification of plant viruses and their vectors in SSA mostly relies on standard PCR and next generation sequencing technologies (NGS). However, it can take up to 6 months before results generated using these approaches are available. The long time taken to detect or identify viruses impedes quick within-season decision making necessary for early action, crop protection advise and disease control measures by farmers. This ultimately compounds the magnitude of crop losses and food shortages suffered by farmers. For the first time globally, the MinION portable pocket DNA sequencer was used to sequence whole plant virus genomes on the farm in Uganda, Tanzania and Kenya and we have reduced the time to diagnosis to 3 hours. In this talk I will outline how we have used the Oxford Nanopore portable genomics technology to identify the begomoviruses causing the devastating cassava mosaic disease, which is ravaging smallholder farmers’ crops in sub-Saharan Africa leaving millions food insecure. I will also cover the gaps in computing we have identified with our on farm genomic sequencing with the hopes of engaging with people in attendance at the Supercomputing Frontiers Europe 2020 into the future.
Dr. Laura Boykin is a TED Senior Fellow (2017), Gifted Citizen (2017) and a computational biologist who uses genomics and supercomputing to help smallholder farmers in sub-Saharan Africa control whiteflies and associated viruses, which have caused devastation of local cassava crops. She recently (2018) been awarded an Honorary Doctorate from the Open University in the UK for her work on whiteflies, viruses and inclusion and diversity in science. Boykin also works to equip African scientists with a greater knowledge of genomics and high-performance computing skills to tackle future insect outbreaks. Boykin completed her PhD in Biology at the University of New Mexico while working at Los Alamos National Laboratory in the Theoretical Biology and Biophysics group and is currently a Senior Research Fellow at University of Western Australia. She was invited to present her lab’s research on whiteflies at the United Nations Solution Summit in New York City for the signing of the Sustainable Development Goals to end extreme poverty by 2030. The team’s latest work to bring portable DNA sequencing to east African farmers has been featured on CNN, BBC World News, BBC Swahili, BBC Technology News, and the TED Fellows Ideas Blog.

Title: The Reality and Tremendous Opportunity of Custom, Open Source Processing
Abstract: The growth of human and business interaction with technology continues to explode. At the literal heart of that technology sits a silicon core, combined with general and specific instructions and connections. The insane cost, risk, development time, necessary volumes, and limited computing demands kept the lucrative chip opportunity within reach of just a handful of companies — focused mostly on general purpose processors. New computing needs in various power and performance dimensions have increased demand and competition for custom processors. This pressure is quietly and rapidly disrupting the processor industry. An Open source approach to processors now reduces risk and investment, with accelerated time to market, and opens the opportunity to thousands of possible custom processors. Learn about the trends, opportunities, and examples — from smart watches to supercomputers!
