Appendix A. A sample program to illustrate messages

This appendix provides sample output for a program run under POE with the maximum level of message reporting. It also points out the different types of messages you can expect, and explains what they mean.

To set the level of messages that get reported when you run your program, you can use the -infolevel (or -ilevel) option when you invoke POE. You can also use the MP_INFOLEVEL environment variable. Setting either of these to 6 gives you the maximum number of diagnostic messages when you run your program. For more information about setting the POE message level, see IBM Parallel Environment for AIX: Operation and Use, Volume 1.

Note that we are using numbered prefixes along the left-hand edge of the following output as a way to refer to particular lines. The prefixes are not part of the output you will see when you run your program. For an explanation of the messages denoted by these numbered prefixes, see Figuring out what all of this means.

This command produces output similar to the following:

> poe hello_world_c -procs 2  -rmpool 1 -infolevel 6
