In computing, a virtual machine (VM) is the virtualization or emulation of a computer system. Virtual machines are based on computer architectures and provide the functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination of the two. Virtual machines differ and are organized by their function, shown here:
John Kenneth Ousterhout is a professor of computer science at Stanford University. He founded Electric Cloud with John Graham-Cumming. Ousterhout was a professor of computer science at University of California, Berkeley where he created the Tcl scripting language and the Tk platform-independent widget toolkit, and proposed the idea of coscheduling. Ousterhout led the research group that designed the experimental Sprite operating system and the first log-structured file system. Ousterhout also led the team that developed the Magic VLSI computer-aided design (CAD) program.
VMware LLC is an American cloud computing and virtualization technology company with headquarters in Palo Alto, California. VMware was the first commercially successful company to virtualize the x86 architecture.
John Leroy Hennessy is an American computer scientist who serves as chairman of Alphabet Inc. (Google). Hennessy is one of the founders of MIPS Technologies and Atheros while also serving as the tenth President of Stanford University. Hennessy announced that he would step down in the summer of 2016. He was succeeded as president by Marc Tessier-Lavigne. Marc Andreessen called him "the godfather of Silicon Valley."
In computer science, cache coloring is the process of attempting to allocate free pages that are contiguous from the CPU cache's point of view, in order to maximize the total number of pages cached by the processor. Cache coloring is typically employed by low-level dynamic memory allocation code in the operating system, when mapping virtual memory to physical memory. A virtual memory subsystem that lacks cache coloring is less deterministic with regards to cache performance, as differences in page allocation from one program run to the next can lead to large differences in program performance.
Richard Farris Rashid is the founder of Microsoft Research, which he created in 1991. Between 1991 and 2013, as its chief research officer and director, he oversaw the worldwide operations for Microsoft Research which grew to encompass more than 850 researchers and a dozen labs around the world.
David Ross Cheriton is a Canadian computer scientist, businessman, philanthropist, and venture capitalist. He is a computer science professor at Stanford University, where he founded and leads the Distributed Systems Group.
The following is a timeline of virtualization development. In computing, virtualization is the use of a computer to simulate another computer. Through virtualization, a host simulates a guest by exposing virtual hardware devices, which may be done through software or by allowing access to a physical device connected to the machine.
Desktop virtualization is a software technology that separates the desktop environment and associated application software from the physical client device that is used to access it.
Giovanni De Micheli is Professor and Director of the Institute of Electrical Engineering and of the Integrated Systems Centre at École Polytechnique Fédérale de Lausanne (EPFL), Switzerland. He is program leader of the Nano-Tera.ch program. Previously, he was Professor of Electrical Engineering at Stanford University. He holds a Nuclear Engineer degree, a M.S. and a Ph.D. degree in Electrical Engineering and Computer Science under Alberto Sangiovanni-Vincentelli.
Nicholas (Nick) William McKeown FREng, is a Senior Fellow at Intel, a professor in the Electrical Engineering and Computer Science departments at Stanford University, and a Visiting Professor at Oxford University. He has also started technology companies in Silicon Valley.
Anant Agarwal is an Indian computer architecture researcher. He is a professor of Electrical Engineering and Computer Science at the Massachusetts Institute of Technology (MIT), where he led the development of Alewife, an early cache coherent multiprocessor, and also has served as director of the MIT Computer Science and Artificial Intelligence Laboratory. He is the founder and CTO of Tilera, a fabless semiconductor company focusing on scalable multicore embedded processor design. He also serves as the CEO of edX, a joint partnership between MIT and Harvard University that offers free online learning.
Mendel Rosenblum is a professor of Computer Science at Stanford University and co-founder of VMware.
Diane B. Greene is an American technology entrepreneur and executive. Greene started her career as a naval architect before transitioning to the tech industry, where she was a founder and CEO of VMware from 1998 until 2008. She was a board director of Google and CEO of Google Cloud from 2015 until 2019. She was also the co-founder and CEO of two startups, Bebop and VXtreme, which were acquired by Google and Microsoft, for $380 million and $75 million.
SimOS was a full system simulator, developed in the Stanford University in the late nineties in the research group of Mendel Rosenblum. It was enabled to run IRIX 5.3 on MIPS, and Unix variants on Alpha.
The Computer Entrepreneur Award was created in 1982 by the IEEE Computer Society, for individuals with major technical or entrepreneurial contributions to the computer industry. The work must be public, and the award is not given until fifteen years after the developments. The physical award is a chalice from sterling silver and under the cup a gold-plated crown.
Wanova, Inc, headquartered in San Jose, California, provides software allowing IT organizations to manage, support and protect data on desktop and laptop computers. Wanova's primary product, Wanova Mirage, was designed as an alternative to server-hosted desktop virtualization technologies.
Jason Nieh is a professor of Computer Science and co-director of the Software Systems Laboratory at Columbia University. He is most well known for his work on virtualization. He was one of the early pioneers of operating-system-level virtualization, introducing key concepts such as process namespaces and file system layers which led to the development of Linux containers and Docker. He was an early proponent of desktop virtualization, conducting many of the early studies demonstrating the feasibility of Virtual Desktop Infrastructure. He developed and influenced many key technologies for Arm virtualization, including the Linux ARM hypervisor, KVM ARM, and Arm architecture features to support virtualization host extensions, nested virtualization, and confidential computing. He was also the first to introduce virtual machines and virtual appliances to teach hands-on computer science courses such as operating systems, which has now become common practice at many universities. Nieh was the technical advisor to nine States regarding the Microsoft antitrust settlement and has been an expert witness before the United States International Trade Commission. He was Chief Scientist of Desktone, which was purchased by VMware, and currently holds the same position at CertiK.
The ACM SIGOPS Mark Weiser Award is awarded to an individual who has shown creativity and innovation in operating system research. The recipients began their career no earlier than 20 years prior to nomination. The special-interest-group-level award was created in 2001 and is named after Mark Weiser, the father of ubiquitous computing.
Marcel Salathé is a Swiss digital epidemiologist. He is currently an associate professor at École Polytechnique Fédérale de Lausanne (EPFL) He is the director of the Lab of Digital Epidemiology, based at EPFL's Geneva Campus. In the first year of the COVID-19 pandemic, Salathé was the most quoted scientist in the Swiss media.
