| 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

| 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

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.
