Its interface is "POSIX - compatible"; by that we mean as close to POSIX.1 as it can be, given - that PACE is not an operating system. And, to avoid name conflicts - with OS APIs, all low-level PACE function names have the - <i><b>pace_</b></i> prefix.</p> - </li> - <li><p>The low-level interface is a C file, so that it can be used in both - C and C++ programs.</p> - </li> - <li><p>The low-level interface is partitioned into multiple files, one per - POSIX.1 section.</p> - </li> - </ul> - - -<h2>ACE uses PACE</h2> - - <p>The ADAPTIVE Communication Environment - <a href="http://www.cs.wustl.edu/~schmidt/ACE.html">(ACE)</a> is a freely - available, open-source, object-oriented - <a href="http://www.cs.wustl.edu/~schmidt/courses.html"> (OO)</a> framework - that implements many core design patterns for concurrent communication - software.</p> - - <p>ACE is currently built on an - <a href="http://www.cs.wustl.edu/~schmidt/ACE-overview.html">OS Adaptation - Layer</a> that abstracts away specific computer architecture / platform - dependencies therfore allowing ACE to be portable across any platform that the - adaptation layer supports.</p> - - <p>ACE also forms the foundation upon which - <a href="http://www.cs.wustl.edu/~schmidt/TAO.html">TAO</a> is built. The - combination of implementing TAO (adding specific functionality to ACE) and - the ever shifting sands of vendor-specific operating systems has grown the ACE - adapatation layer from a small core of critial functions to over 30,000 lines - of interdependent code. The development of TAO tied in with requests from our - sponsors as well as suggestions from the development community at large - contributed to our decision to re-engineer ACE' adaptation layer. PACE is one - part of this effort.</p> - -<h2>PACE Objectives</h2> - - <p>Some objectives of this phase of ACE' development (PACE) include:</p> - - <ul> - <li><p><b>ACE Developers:</b> Make the low level abstraction layer code more - maintainable.<br> <i>(reduce file size and file interdependence - improve - code modularity)</i></p></li> - <li><p><b>ACE Users:</b> Reduce ACE' footprint.<br> - <i>(this is not a one step task by any stretch of the imagination, but we - will begin breaking out the code into separate files - allowing developers - the opportunity option to compile and link specific object files to their - executables instead of the entire ACE adaptation layer library)</i></p></li> - <li><p><b>ACE Users:</b> Update the adaptation layer to be POSIX compliant.<br> - <i>(see next)</i></p></li> - <li><p><b>ACE Users:</b> Split the adaptation layer to support both a <b>C</b> - api (PACE) as well as a set of <b>C++</b> wrapper classes (ACE_OS) - allowing <i><b>both C & C++</b></i> developers to call directly into the - low level api.<br> - <i>(encapslate POSIX and system calls in <b>C</b> wrappers and re-write the - (ACE_OS) adaptation layer to transparently call into the POSIX emulation api - (PACE))</i></p></li> - <li><p>ACE Users:</b>ACE will not change its public interface, it will only add low - level <b>C</b> operations to its repertoire. As is obvious, software built on - this adaptation layer is portable across the various platforms that ACE - supports. This provides backward compatilibity for people already using the - current <b>C++</b> (ACE_OS) adaptation layer of ACE.</p> - </ul> - - <p>This is an open-source project maintained by: - <ul> - <li><a href="http://www.cs.wustl.edu/~schmidt">Dr. Douglas Schmidt</a> of the - <a href="http://www.cs.uci.edu/">University of California - Irvine</a></li> - <li><a href="http://www.cs.wustl.edu/~levine">Dr. David Levine</a> of - <a href="http://www.cs.wustl.edu/">Washington University - St. Louis</a></li> - <li>their respective sister <a href="http://www.cs.wustl.edu/~doc"> - <b><font color="red">D</font></b>istributed - <b><font color="red">O</font></b>bject - <b><font color="red">C</font></b>omputing</a> research groups.</li> - </ul> - </p> - - <p>Additional information regarding - <a href="http://www.cs.wustl.edu/~schmidt/ACE.html">ACE</a> and - <a href="http://www.cs.wustl.edu/~luther/PACE">PACE</a> and - <a href="http://www.cs.wustl.edu/~schmidt/TAO.html">TAO</a> is available - as well as a <a href="http://www.cs.wustl.edu/~schmidt/TAO-obtain.html">full - source distribution</a> of TAO + ACE + PACE. - - <p>If you have any questions, suggestions or contributions regarding PACE, - please <a href="mailto:luther@cs.wustl.edu">write</a> to us or subscribe to the - pace-users mailing list (send email to <a href="mailto:majordomo@cs.wustl.edu"> - majordomo@cs.wustl.edu</a> with <b>"subscribe pace-users"</b> in the <i>body</i>, - not the subject line ;-)</p> -</td></tr> - -<!-- line --> -<tr><td> -<div align="center"><img src="../IMAGES/line_mid_700.gif"></div> -</td></tr> - -<tr><td> -<div align="center"><a href="http://www.cs.wustl.edu/~luther/PACE">home</a></div> -</td></tr> -</table> - -</body> -</html> |
