See: New York Stock Exchange : SGI), a world leader in high-performance computing High-speed computing, which typically refers to supercomputers used in scientific research. , complex data management, visualization products and services, has announced the successful conclusion of an experiment in long-distance visual serving. The demonstration featured the SGI Visual Serving environment based on SGI OpenGL Vizserver and was conducted June through August 2001 using CANARIE CANARIE Canadian Network for the Advancement of Research Industry and Education
CANARIE Canada Network for the Advancement of Research Industry and Education , Inc.'s (Canada's advanced Internet development organization) high-bandwidth network, CA*net3, which stretches across Canada Across Canada was an afternoon program that formerly aired on The Weather Network. The segment ran from early 1999 until mid 2002. The show ran from 3:00PM ET until 7:00 PM ET. . OpenGL Vizserver enables users of inexpensive, general-purpose or commodity computers running IRIX A Unix-based operating system from SGI that is used in its computer systems from desktop to supercomputer. It is an enhanced version of Unix System V Release 4. IRIX integrates the X Window system with OpenGL, creating the first real time 3D X environment. , Linux, Solaris or Windows NT (Windows New Technology) A 32-bit operating system from Microsoft for Intel x86 CPUs. NT is the core technology in Windows 2000 and Windows XP (see Windows). Available in separate client and server versions, it includes built-in networking and preemptive multitasking. operating systems Operating systems can be categorized by technology, ownership, licensing, working state, usage, and by many other characteristics. In practice, many of these groupings may overlap. to access the full power of SGI Onyx The SGI Onyx is a series of visualisation systems designed and manufactured by SGI, introduced in 1993 and offered in two models, deskside and rackmount. The Onyx's basic system architecture is based on the SGI Challenge servers, but with the notable inclusion of graphics hardware. 3000 series high-performance visualization systems. Technical and creative professionals will benefit from the ability to interactively access graphics over increasingly long distances via the network or grid.
Visual Serving solutions from SGI give networked users of desktop systems the ability to interact visually with powerful remote SGI Onyx 3000 series visualization systems. Visual serving is a key component of SGI's grid computing grid computing, the concurrent application of the processing and data storage resources of many computers in a network to a single problem. It also can be used for load balancing as well as high availability by employing multiple computers—typically personal solutions that make data, computation power and visualization universally available via the grid. Grid computing is an approach by which the Internet or dedicated networks are used to interconnect a wide variety of geographically distributed computational resources, such as supercomputers, computer clusters, storage systems, and visualization systems, and present them as a single, unified resource.
SGI chose to conduct this long-distance trial using the CANARIE network because of its excellent high-bandwidth optical infrastructure and support along with on-going industrial?academic partnerships with Canadian universities. Using an SGI Onyx family visualization system located at McGill University's McConnell Brain Imaging Centre (BIC BIC
See: Bank Investment Contract ), the trial involved running graphics from cities ranging from 100 to 1,900 miles away.
"We were very pleased to participate in this groundbreaking exercise with SGI, and we enjoyed working with their experienced personnel," said Peter Marshall Peter Marshall may refer to:
The results reconfirmed that graphics generated on an SGI Onyx family system in Montreal could be accessed interactively on desktop workstations located in Calgary in a manner truly beneficial to long-distance users. This enhanced networking capability will be a key element in a $30 million expansion of BIC to link with other institutions within the Montreal Consortium for Brain Imaging Research (MCBIR). Part of the MCBIR vision is the creation of a 3D-image database accessible by the global brain imaging research community.
"Our recent purchase of an SGI Onyx 3400 system and an SGI Origin 3800 system has been a wonderful addition to our lab, enabling the expansion of our brain imaging research. Now, with the successful long-distance experiments on OpenGL Vizserver, we can share that information with researchers, scientists and students across Canada and around the world, receiving their valuable feedback and contributions in return," said Dr. Alan Evans Alan Evans may refer to:
"Visual serving represents a fundamental shift in how creative and technical professionals can work with visualization software and SGI leads the way on that frontier," said Greg Estes, vice president of marketing at SGI. "No longer will users be required to be in close physical proximity to high-end graphics computers to take advantage of their power. Instead, SGI enables users to visually tap into remote graphics, computing, and complex data management power from a variety of workstations."
The key concept underlying the development of grid computing is that users transparently take advantage of resources available over the network. In some cases, compute resources may be selected because they are close to the data that is being manipulated or in other cases the data may be moved to the location of the computing resource. However, under no circumstance are users asked to leave their desks and travel to the location of the data or computational resource.
Visual serving unlocks the power of the grid so users anywhere can interact with the results of supercomputing calculations. As the CANARIE visual serving demonstration illustrates, scientists all over Canada now Canada Now (more formally CBC News: Canada Now) is the early-evening national news program aired on CBC Television, the main English television network of the Canadian Broadcasting Corporation, between 2000 and 2007. have the ability to utilize computing and visualization resources anywhere in the country and to interactively visualize them at their desktop. The result is greatly expanded access Expanded access refers to the inclusion of patients in a clinical trial for a new therapeutic treatment or chemical entity, where those patients would not satisfy the enrolment criteria for the scientific study in progress. to powerful scientific visualizations and increased productivity for both local and remote users.
CANARIE's CA*net3 network uses high-speed optical transport technology to provide massive high-bandwidth connectivity between major sites. The design of the network limited the effects of bandwidth constraints so that today's networks can serve as effective substrates for long-distance graphics interactivity.
The OpenGL Vizserver experiment used commercial visualization software based on OpenGL Performer OpenGL Performer, formerly known as IRIS Performer and commonly referred to simply as Performer, is a commercial library of utility code built on top of OpenGL for the purpose of enabling hard real-time visual simulation applications. and focused on optimizing frame rates across various distances. The size and interactive frame rate of the graphics window between the connected computers was affected by two factors: bandwidth and image compression Noun 1. image compression - the compression of graphics for storage or transmission
compression - encoding information while reducing the bandwidth or bits required . The lower the available bandwidth, the smaller the window needed to maintain interactivity. This effect was overcome by the application of image compression technology, which allowed interactive frame rates to be maintained for larger windows. As the distance increased between the graphics computer and the remote user, the user's interactive experience remained unchanged.
As expected, the results depended on the size of the interactive OpenGL window and ranged from 5 to 25 frames per second. These results illustrated little variation with distance and were completely consistent with the 20Mb-per-second connection used for this test.
In addition to this successful demonstration of long-distance visual serving, the strong collaborative relationship established among SGI, CANARIE and the Canadian academic community will fuel future investigation and development for OpenGL Vizserver technology.
