ACE provides a rich set of reusable C++ -wrappers and frameworks that perform common communication software -tasks across a range of OS platforms, including Win32 (i.e., WinNT -3.5.x/4.x, Win95, and WinCE), most versions of UNIX (e.g., SunOS 4.x -and 5.x, SGI IRIX 5.x and 6.x, HP-UX 9.x, 10.x, and 11.x, DEC UNIX -4.x, AIX 4.x, Linux, SCO, UnixWare, NetBSD, and FreeBSD), real-time -operating systems (e.g., VxWorks, Chorus, LynxOS, and pSoS), and MVS -OpenEdition. A single source tree is used for all these platforms and -porting ACE to other platforms is relatively easy. - -The communication software components provided by ACE include event -demultiplexing and event handler dispatching, service initialization, -interprocess communication, shared memory management, message routing, -dynamic (re)configuration of distributed services, multi-threading, -and concurrency control. There are both C++ and Java versions of ACE -available. - -ACE is targeted for developers of high-performance and real-time -communication services and applications on UNIX, POSIX, and Win32 -platforms. ACE simplifies the development of OO network applications -and services that utilize interprocess communication, event -demultiplexing, explicit dynamic linking, and concurrency. ACE -automates system configuration and reconfiguration by dynamically -linking services into applications at run-time and executing these -services in one or more processes or threads. - -ACE is currently used in commercial projects and products by dozens of -companies including Ericsson, Bellcore, Siemens, Motorola, Kodak, -Boeing, Lucent, DEC, Lockheed Martin, and SAIC. Commercial support -for ACE is available at http://www.riverace.com. - ----------------------------------------- - -C++ Wrappers for OS Interfaces - -The lower-level portions of ACE provide a set of portable and -type-secure C++ wrappers that encapsulate the following C language OS -interfaces: - - . IPC mechanisms - -- e.g., Internet- and UNIX-domain sockets, TLI, Named - Pipes (for UNIX and Win32) and STREAM pipes; - - . Event demultiplexing - -- e.g., select(), poll(), and Win32 - WaitForMultipleObjects and I/O completion ports; - - . Multi-threading and synchronization - -- e.g., Solaris threads, POSIX Pthreads, and Win32 - threads; - - . Explicit dynamic linking - -- e.g., dlopen/dlsym on UNIX and LoadLibrary/GetProc - on Win32; - - . Memory-mapped files and shared memory management - -- e.g., BSD mmap(), SYSV shared memory, and Win32 - shared memory; - - . System V IPC - -- e.g., shared memory, semaphores, message queues. - -The OS Adaptation Layer shields the upper levels of ACE from platform -dependencies associated with the underlying OS interfaces. - ----------------------------------------- - -Frameworks and Class Categories - -ACE also contains a higher-level network programming framework that -integrates and enhances the lower-level C++ wrappers. This framework -supports the dynamic configuration of concurrent distributed services -into applications. The framework portion of ACE contains the -following class categories: - - . The Reactor - -- Supports both Reactive and Proactive I/O; - - . The Service Configurator - -- Support dynamic (re)configuration of objects; - - . The ADAPTIVE Service Executive - -- A user-level implementation of System V STREAMS, - that supports modular integration of - hierarchically-related communicaion services; - - . Concurrency - -- Various types of higher-level concurrency - control and synchronization patterns (such as - Polymorphic Futures and Active Objects); - - . Shared Malloc - -- Components for managing dynamically allocation - of shared and local memory; - ----------------------------------------- - -Distributed Services and Components - -Finally, ACE provides a standard library of distributed services that -are packaged as components. These service components play two roles -in ACE: - - 1. They provide reusable components for common distributed - system tasks such as logging, naming, locking, and time - synchronization. - - 2. They illustrate how to utilize ACE features such as the - Reactor, Service Configurator, Service Initialization, - Concurrency, and IPC components. - ----------------------------------------- - -Middleware Applications - -ACE has been used in research and development projects at many -universities and companies. For instance, it has been used to build -avionics systems at Boeing, telecommunication systems at Bellcore, -Ericsson, Motorola, and Lucent; medical imaging systems at Siemens and -Kodak; and many academic research projects. Two example middleware -applications provided with the ACE release include: - - 1. The ACE ORB (TAO) -- TAO is a real-time implementation of - CORBA built using the framework components and patterns - provided by ACE. - - 2. JAWS -- JAWS is a high-performance, adaptive Web server - built using the components in ACE. - ----------------------------------------- - -OBTAINING ACE - -The current ACE release is provided as a tar file that is around 3 Meg -compressed using GNU gzip. ACE may be obtained electronically from -http://www.cs.wustl.edu/~schmidt/ACE-obtain.html. This release -contains the source code, test drivers, and example applications -(including JAWS) for C++ wrapper libraries and the higher-level ACE -network programming framework developed as part of the ADAPTIVE -project at the University of California, Irvine and at Washington -University, St. Louis. - -You can get The ACE ORB (TAO) in a companion release at -http://www.cs.wustl.edu/~schmidt/TAO.html. - ----------------------------------------- - -ACE DOCUMENTATION AND TUTORIALS - -Many of the C++ wrappers and higher-level components have been -described in issues of the C++ Report, as well as in proceedings of -many journals, conferences, and workshops. - -A collection of white papers and tutorial handouts are included at -ftp://wuarchive.wustl.edu/languages/c++/ACE/ACE-documentation. This -directory contains postscript versions of various papers that describe -different aspects of ACE. - -I update these papers periodically to reflect changes to the ACE -architecture. Therefore, you might want to check the date on the -files to make sure that you have read the most recent versions of -these papers. - -This material is also available available via the WWW at URL: - -http://www.cs.wustl.edu/~schmidt/ACE.html - ----------------------------------------- - -ACE MAILING LIST AND NEWSGROUP - -A mailing list, ace-users@cs.wustl.edu, is available for discussing -bug fixes, enhancements, and porting issues regarding ACE. Please -send mail to me at the ace-users-request@cs.wustl.edu if you'd like to -join the mailing list. There is also a USENET newsgroup called -comp.soft-sys.ace. - ----------------------------------------- - -BUILDING AND INSTALLING ACE - -Please refer to the http://www.cs.wustl.edu/~schmidt/ACE-install.html -file for information on how to build and test the ACE wrappers. The -BIBLIOGRAPHY file contains information on where to obtain articles -that describe the ACE wrappers and the ADAPTIVE system in more detail. - -The current release has been tested extensively, but if you find any -bugs, please report them to the ACE mailing list -ace-users@cs.wustl.edu using the $ACE_ROOT/PROBLEM-REPORT-FORM. -Please use the same form to submit questions, comments, etc. -To ensure that you see responses, please do one of the following: - - 1) Subscribe to the ace-users mail list, by sending email with - contents "subscribe ace-users" to majordomo@cs.wustl.edu. - - 2) Or, monitor the comp.soft-sys.ace newsgroup for responses. - ----------------------------------------- - -ACKNOWLEDGEMENTS - -Please see the file `$ACE_ROOT/THANKS' for a list of the thousands of -people who've contributed to ACE and TAO over the years. |
