Katarzyna Keahey is a Senior Computer Scientist at Argonne National Laboratory and the Consortium for Advanced Science and Engineering (CASE) of the University of Chicago. [9] She is a Principal Investigator (PI) of the Chameleon project, which provides an innovative experimentation platform for computer science systems experiments. [10] She created Nimbus, one of the first open source implementations of infrastructure-as-a-Service (IaaS), and co-founded the SoftwareX journal, publishing software as a scientific instrument. [5] [11] [2]
Keahey attended the Gdańsk University of Technology where she obtained her magister inżynier in informatics in 1992. She received her M.S. in computer science at Indiana University Bloomington in 1994, and later went on to earn her Ph.D. in computer science at Indiana University in 1998. [12] Her Ph.D. dissertation was titled, An Architecture for Application-Level Parallel Distributed Computation, and was supervised by Dennis Gannon.
Her research interests include cloud computing, [1] [13] resource management, [7] [14] in particular the exploration of how cloud and high-performance/scientific resources can co-exist and complement each other, [8] [15] [16] infrastructure operation, [3] and Internet of Things (IoT)/cloud continuum. She is currently developing methods that support capturing, replicating, and publishing experiments digitally. [3]
A supercomputer is a type of computer with a high level of performance as compared to a general-purpose computer. The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS). Since 2017, supercomputers have existed which can perform over 1017 FLOPS (a hundred quadrillion FLOPS, 100 petaFLOPS or 100 PFLOPS). For comparison, a desktop computer has performance in the range of hundreds of gigaFLOPS (1011) to tens of teraFLOPS (1013). Since November 2017, all of the world's fastest 500 supercomputers run on Linux-based operating systems. Additional research is being conducted in the United States, the European Union, Taiwan, Japan, and China to build faster, more powerful and technologically superior exascale supercomputers.
Grid computing is the use of widely distributed computer resources to reach a common goal. A computing grid can be thought of as a distributed system with non-interactive workloads that involve many files. Grid computing is distinguished from conventional high-performance computing systems such as cluster computing in that grid computers have each node set to perform a different task/application. Grid computers also tend to be more heterogeneous and geographically dispersed than cluster computers. Although a single grid can be dedicated to a particular application, commonly a grid is used for a variety of purposes. Grids are often constructed with general-purpose grid middleware software libraries. Grid sizes can be quite large.
Argonne National Laboratory is a federally funded research and development center in Lemont, Illinois, United States. Founded in 1946, the laboratory is owned by the United States Department of Energy and administered by UChicago Argonne LLC of the University of Chicago. The facility is the largest national laboratory in the Midwest.
Jack Joseph Dongarra is an American computer scientist and mathematician. He is a University Distinguished Professor Emeritus of Computer Science in the Electrical Engineering and Computer Science Department at the University of Tennessee. He holds the position of a Distinguished Research Staff member in the Computer Science and Mathematics Division at Oak Ridge National Laboratory, Turing Fellowship in the School of Mathematics at the University of Manchester, and is an adjunct professor and teacher in the Computer Science Department at Rice University. He served as a faculty fellow at the Texas A&M University Institute for Advanced Study (2014–2018). Dongarra is the founding director of the Innovative Computing Laboratory at the University of Tennessee. He was the recipient of the Turing Award in 2021.
High-performance computing (HPC) uses supercomputers and computer clusters to solve advanced computation problems.
Ian Tremere Foster is a New Zealand-American computer scientist. He is a distinguished fellow, senior scientist, and director of the Data Science and Learning division at Argonne National Laboratory, and a professor in the department of computer science at the University of Chicago.
Carl Kesselman is an American computer scientist specializing in grid computing technologies. This term was developed by him and professor Ian Foster in the book The Grid: Blueprint for a New Computing Infrastructure. He and Foster are winners of the British Computer Society's Lovelace Medal for their grid work. He is institute fellow at the University of Southern California's Information Sciences Institute and a professor in the Epstein Department of Industrial and Systems Engineering, at the University of Southern California.
TeraGrid was an e-Science grid computing infrastructure combining resources at eleven partner sites. The project started in 2001 and operated from 2004 through 2011.
Sun Cloud was an on-demand cloud computing service operated by Sun Microsystems prior to Sun's acquisition by Oracle Corporation. The Sun Cloud Compute Utility provided access to a substantial computing resource over the Internet for US$1 per CPU-hour. It was launched as Sun Grid in March 2006—the same month Amazon Web Services began offering their first IT infrastructure services. It was based on and supported open source technologies such as Solaris 10, Sun Grid Engine, and the Java platform.
Charlie Catlett is a senior computer scientist at Argonne National Laboratory and a visiting senior fellow at the Mansueto Institute for Urban Innovation at the University of Chicago.
