PyOMP: Multithreaded Parallel Programming in Python
Python is a widely used language in scientific computing. When the goal is high performance, however, Python lags far behind low-level languages such as C and Fortran. To support applications that stress performance, Python needs to access the full capabilities of modern CPUs. That means support for parallel multithreading. In this article, we describe PyOMP, a system that enables OpenMP in Python. Programmers write code in Python with OpenMP, Numba generates code that compiles to LLVM, and the resulting programs run with performance that approaches that from code written with C and OpenMP. In this article, we provide an u...

FPGAs in the Cloud
As cloud computing grows, the types of computational hardware available in the cloud are diversifying. Field programmable gate arrays (FPGAs) are a relatively new addition to high-performance computing in the cloud, with the ability to accelerate a range of different applications, and the flexibility to offer different cloud computing models. A new and growing configuration is to have the FPGAs directly connected to the network and thus reduce the latency in delivering data to processing elements. We survey the state of the art in FPGAs in the cloud and present the Open Cloud Testbed, a testbed for research and experimenta...

Inclusivity Bugs and the Language We Use
If we knew many terms and phrases we commonly use such as, for example, sanity check, grandfathered, ladies and gentlemen or low man on the totem pole can discourage coworkers, colleagues, collaborators and other potential contributors from participating in our projects with their full authentic selves, would we still use them?

It’s Time to Talk About HPC Storage: Perspectives on the Past and Future
High-performance computing (HPC) storage systems area key component of the success of HPC to date. Recently, we have seen major developments in storage-related technologies, as well as changes to how HPC platforms are used, especially in relation to artificial intelligence and experimental data analysis workloads. These developments merit a revisit of HPC storage system architectural designs. In this article, we discuss the drivers, identify key challenges to status quo posed by these developments, and discuss directions future research might take to unlock the potential of new technologies for the breadth of HPC applicati...

From Molecules to Quantum Computers: A Research Retrospective
Quantum computers promise to unlock new capabilities in areas ranging from the study of physical systems to cryptography. The field of quantum computing is built on the solid foundations of computational science that the Department of Energy Computational Science Graduate Fellowship continues to build. In this special research retrospective, I discuss my path in quantum computing research that receiving this award made possible. Starting with an introduction to quantum computing, I discuss how variational methods came to be popular on quantum computing hardware today, and the need to mitigate errors. The setting of variati...

How to Model for a Living: The CSGF as a Catalyst for Supermodels
Models are ubiquitous and uniting tools for computational scientists across disciplines. As a computational biophysical chemist, I apply multiple models to understand and predict how molecules recognize and interact with each other in complex, dynamic biological environments. The Department of Energy Computational Science Graduate Fellowship (DOE CSGF) cultivates interest in engaging in models from an multidisciplinary perspective and enables junior scientists to see how computational modeling is a creative and collaborative process. In the following, I describe ways, based in part on my own experiences as a CSGF recipient...

Research in Inverse Problems and Training in Computational Science: A Reflection on the Importance of Community
This article is a retrospective of the people and experiences that have had significant impacts on my research portfolio, on my teaching and mentoring of students, and on my involvement in the scientific community. It begins in 2006 when, as a second-year Ph.D. student in the Department of Mathematics and Computer Science, Emory University, I was awarded the Department of Energy Computational Science Graduate Fellowship.
