|Online Information Resources
|If you have a question about the SP, PSSP, or a related product, the following
|online information resources make it easy to find the information:
|Access the new SP Resource Center by issuing the command:
|/usr/lpp/ssp/bin/resource_center
|Note that the ssp.resctr fileset must be installed before you can do this.
|If you have the Resource Center on CD-ROM, see the readme.txt file for
|information on how to run it.
|Access the RS/6000 Web Site at: http://www.rs6000.ibm.com.
|Getting the Books and the Examples Online
|All of the PE books are available in Portable Document Format (PDF). They are
|included on the product media (tape or CD-ROM), and are part of the ppe.pedocs
|file set. If you have a question about the location of the PE softcopy books, see
|your system administrator.
|To view the PE PDF publications, you need access to the Adobe Acrobat Reader
|3.0.1. The Acrobat Reader is shipped with the AIX Version 4.3 Bonus Pack and is
|also freely available for downloading from the Adobe web site at URL
|http://www.adobe.com.
|As stated above, you can also view or download the PE books from the IBM
|RS/6000 Web site at http://www.rs6000.ibm.com. The serial and parallel
|programs that you find in this book are also available from the IBM RS/6000 Web
|site. At the time this manual was published, the full path was
|http://www.rs6000.ibm.com/resource/aix_resource/sp_books. However, note
|that the structure of the RS/6000 Web site can change over time.
|What's New in PE 2.4?
|AIX 4.3 Support
|With PE 2.4, POE supports user programs developed with AIX 4.3. It also supports
|programs developed with AIX 4.2, intended for execution on AIX 4.3.
| Parallel Checkpoint/Restart
|This release of PE provides a mechanism for temporarily saving the state of a
|parallel program at a specific point (

checkpointing

), and then later restarting it from
|the saved state. When a program is checkpointed, the checkpointing function
|captures the state of the application as well as all data, and saves it in a file. When
|the program is restarted, the restart function retrieves the application information
|from the file it saved, and the program then starts running again from the place at
|which it was saved.
