The telescope is planned to be operated during a series of long-duration balloon flights in order to obtain time series of spectra and images at the diffraction-limit and to study the UV spectral region down to 200 nm, which is not accessible from the ground. The central aim of Sunrise is to understand the structure and dynamics of the magnetic field in the solar atmosphere. Interacting with the convective flow field, the magnetic field in the solar photosphere develops intense field concentrations on scales below 100 km, which are crucial for the dynamics and energetics of the whole solar atmosphere. In addition, Sunrise aims to provide information on the structure and dynamics of the solar chromosphere and on the physics of solar irradiance changes.

ACE+TAO is being used to develop its control system (GCS). GCS is responsible for controlling the different mechanisms of the telescope, e.g. mount, active optics, instruments, as well as for the data acquisition and adaptive observation scheduling. Specifically, the primary mirror control system may have to work at 200 Hz to maintain alignment of a set of 36 mirror-segments, weighing 400 kg each, within an accuracy of some nanometers. GCS will run on a heterogeneous platform: VME CPU boards with VxWorks for the real-time tier written in C++ and Solaris workstations for the coordinating part and for the user interfaces written in Java. All the nodes are connected by a high speed ATM network.

    ACE+TAO provides a uniform architecture, simplifies portability between VxWorks and Solaris, and interoperates with the Java2 ORB to communicate with the user interfaces. The real-time capabilities of TAO are extensively exercised through the use of the Real-Time Event Service to drive the control loops, status monitoring, alarm propagation, etc.

  6. ACE+TAO are being used in a passive radar project at the University of Washington. The instrument in this project relies on an ability to have two receivers synchonously sample at a rate of 250 ksamp/sec for relatively long times (seconds now, minutes later), the trick being that the two receivers are separated by 150 km. ACE+TAO are used multiple times in this project: for the experiment coordination, data transport, and ultimately thread management on the ``supercomputer.''

  7. The BABAR experiment at the Stanford Linear Accelerator Center is using both ACE and TAO within selected places of the data acquisition system. We are using ACE transparently via the "CMLOG" software from CEBAF (Jefferson Lab), and in part of our Unix-based event delivery software. In addition, we are using TAO as a mechanism to monitor and control parts of the DAQ system. The code to be monitored/controlled is C++ and the GUI is Java (using JavaIDL). Finally, a distributed histogram package being developed at Caltech will shortly use TAO.

    The experiment is a project located on the Stanford University campus and involves a new electron-positron asymmetric collider used to produce large numbers of B and B-bar (anti-B) mesons (you can guess how the collaboration got its name). The physics is focused on investigating differences in the behavior of matter and anti-matter by observing the decay products of the B and B-bar mesons. This project involves over 600 physicists and engineers representing ~80 institutions from 9 countries. Work started in the late 1980s and the first data is scheduled to be collected in the Spring of 1999. The experiment will continue running for five to ten years. More info may be found here:

    There is a server framework in place that allows creation of multiple independent servers running in dedicated threads and sharing the same executable. Architecture uses Stream, Module, Task, Reactor, Thread_Manager classes. Utilization domain of servers sharing the same address space and running in different threads of control is similar to the one of a shared memory communication between servers, but implementation is much more flexible and cleaner. As an example, we may draw any in-memory data server, that should update (on the fly) historical server of the same data. In our case they share the same repository, which is the only point of contact for these two servers. There are three non-trivial areas in such architecture: signal handling, threads dispatching, network dispatching. Servers register their signals with a dedicated thread running a signal reactor. Each server thread has a dedicated reactor to process network IO and dedicated thread manager to provide effective shutdown and specific resources manipulations. Also every server has its own resource manager to initialize and track down specific resources. Another very interesting and useful application of ACE in our system is Stream class utilization in conjunction with MessageBlock. Stream/Module/Task/MessageBlock provide very efficient redirection of messages and their hierarchical processing, facilitating creation of functional framework with predefined protocol parsers, connector/acceptor factories. This makes possible to concentrate server development on business logic rather than on details of how to communicate with low level network API. Maintenance is another key aspect that is much easier to keep up now, due to a true OO nature of the framework. Modules could be unplugged and adjusted independently (from each other as well as underlying network protocol). If you have any questions please don't hesitate to ask.

    TAO will not be used in any data paths.

    This system is implemented on an array of Intel-i960-based, custom SBCs running VxWorks, an Intel-x86 subsystem running Solaris 2.6 and some number of SPARC Ultra subsystems running Solaris 2.6. On the subsystems running Solaris, several processes will be deployed on each processor. Since the processes are heavily multithreaded, the thread-per-request style of concurrency will likely be used.

Robotics

  1. RECIPE, which is an image capture and processing system designed for use on autonomous robots at the University of Bonn, Germany.

  2. ACE+TAO are being used in a joint project at the Clinic of Craniofacial Surgery of the University of Heidelberg and the engineers of the Institute of Process Control and Robotics of the University of Karlsruhe to develop a computer and robot-aided operating theatre.

Travel Planning and Reservation Systems

  1. The Weather Channel uses TAO as the basis for their weather.com website.

  2. AirSage is using ACE+TAO to provide an intelligent traffic road map based on online analysis of cell phone signals. AirSage provides comprehensive traffic information. AirSage utilizes anonymous and aggregate signaling data from wireless carrier networks to provide traffic information for metropolitan areas and rural highways throughout the country. Our patented technology delivers traffic speeds, travel times, and other transportation information at a fraction of the cost of traditional traffic monitoring solutions.

  3. TAO is used by the Sabre Travel Network for their online reservation systems.

  4. TAO is used by Travelocity for their online reservation systems.

  5. ACE is used to connect travel agents to travel products and Airline Reservation systems at Travel Industra Automated Systems (TIAS), Australia

  6. MapQuest.com is using ACE to create a server framework from which a few (and all future) servers are derived. By using ACE and some of its frameworks, has made their development process much faster, but also portable.

Testing and Measurement Equipment

  1. Integrated Measurement Systems in Beaverton, Oregon is using ACE in its Vanguard High Speed Digital IC Validation System. A SIMD supercomputer used in the development and test of the next generation of high-end microprocessors. ACE is an integral part of the client server software which allows the Gigabit IC validation system to be accessed from anywhere on the Internet.

  2. ACE is used in a multiplatform tool to test the integrity of system platforms and numerous configurations at Digital Equipment Corp (DEC).

  3. Cadence Design Systems, Inc. is using portions of ACE for a current server that lets multiple application communicate to an Integrated Circuit tester.
