Quality Assurance and Coding Standards for Parallel Software on POWER systems - Manuel, Appentra Solutions
The automation of testing is critical in software development to improve quality assurance (QA), but today 80% of testing is manual (Gartner) and $32b is spent annually on QA (IDC/Nelson Hall). Coding standards in automotive and cybersecurity (e.g. CWE, MISRA) provide developers with rules and recommendations to prevent faulty code patterns. Parallel programming is challenging and, thus, QA and coding standards are critical for HPC programmers, particularly for industry and novice programmers. The ever-increasing complexity of HPC software and hardware pushes the developers to critically reevaluate testing methods, but, there is no coding standard for parallel programming yet. We will present an ongoing effort to collect the best practices of parallel programming experts and to develop new static code analysis tools specialized in parallelism to ensure code compliance on POWER systems.

E4S: Extreme-scale Scientific Software Stack - Sameer Shende, University of Oregon
The DOE Exascale Computing Project (ECP) Software Technology focus area is developing an HPC software ecosystem that will enable the efficient and performant execution of exascale applications. The Extreme-scale Scientific Software Stack (E4S) [https://e4s.io], is a coherent software stack that will enable application developers to write parallel applications that can target diverse exascale architectures. E4S provides both source builds through the Spack platform and a set of containers that feature a broad collection of HPC software packages. E4S exists to accelerate the development, deployment, and use of HPC software, lowering the barriers for HPC users. It provides container images, build manifests, and turn-key, from-source builds of popular HPC software packages developed as Software Development Kits (SDKs). It will introduce the E4S containers are being deployed at the HPC systems at DOE national laboratories using Singularity, Shifter, and Charliecloud container runtimes.

The "New Normal" or An Evolution - David Leichner, SQREAM
The "New Normal" that we are experiencing with COVID-19 together with the exponential growth of IoT devices and the digitalization taking hold in the market, is moving us out of the Big Data generation and into the era of Massive Data. Enterprises who were struggling to keep up with maintaining and analyzing the data in their legacy Data Warehouses and data lakes, are being completely overwhelmed with the rapid growth of data that they are experiencing. This session will discuss various ways that companies are changing their data management infrastructure to try to keep up. It will look at the movement to the cloud, upgrades of existing legacy systems and other technologies being implemented to resolve some of these issues. The session will also highlight the use of POWER 9 and GPUs as the underlying processing power being used to resolve these challenging issues.

Parallel Biological Sequence Comparison in Large GPU Clusters - Alba Cristina Magalhaes Alves de Melo, University of Brasilia, Brazil
Pairwise Biological Sequence Comparison is an important Bioinformatics application, which is executed many times daily all over the world. In order to accelerate Biological Sequence Comparison applications, GPUs have been used for more than a decade, with very good results. In this talk, we present CUDAlign, a fine-grained multi-GPU parallel strategy to compare huge DNA sequences in hundreds of GPUs. CUDAlign uses parallelogram-shaped parallelism, overlapping of computation and communication, an innovative speculation technique and has pruning capabilities. We show that CUDAlign is able to attain the best performance in the literature for comparison tools with GPUs. We also discuss CUDAlign's energy consumption. We present ongoing work on pruning with multiple GPUS and show some results in an IBM Power9 + NVidia Volta platform. Finally, we discuss open challenges and research directions.

Onstitute: A Collaborative Online Education Platform with Innoative Data-Education Curriculum - Arghya Kusum Das, University of Wisconsin-Platteville
Starting from enterprise applications to scientific and engineering applications to applications in humanities and liberal arts need data analytics. However, with the current expanse of data science education, it is far from satisfying this huge demand for skilled data-labors which is growing exponentially. Data-education curriculums should be innovated to teach students from multiple disciplines regarding analytics with hands-on experience also required demonstrating the scale of applications. In this presentation, I will present 'Onstitute', a collaborative online education platform, that brings real-world data analytics experience at scale to the students utilizing the power of virtualization on top of cutting edge HPC technology such as, POWER-based hardware. I will demonstrate and discuss the innovative features of the platform together with curriculum plans, real case studies, and a future roadmap to improve the data-learning-outcomes of the students from different backgrounds.

Benchmarking Graphical Models on POWER with Healthcare Applications - Radha Nagarajan, Marshfield Clinic Research Institute & Arghya Kusum Das, University of Wisconsin-Platteville
Graphical models, in particular, that have the ability to validate hypothesized associations from multivariate data and discover novel, undocumented, causal associations have seen increasing applications in healthcare that has witnessed a surge in digitization and adoption of data-driven and evidence-based approaches to assist in decision making. Structure learning algorithms that form the core of graphical modeling and aim to decipher associations between the variables of interest from the given data fall under three broad categories, namely constraint-based, search and score, and hybrid. These computationally intensive algorithms need parallelization across HPC environments for enhanced performance. In this presentation, we will discuss the performance of established structure learning algorithms across POWER9 systems with and without GPUs across large data sets. Our approach will be open-sourced for enhanced transparency and reproducibility and adoption in education and research.
