<a NAME="migration_help"></a>Appendix: Using the test script <i>test_zoltan</i></h2>
|
||
|
|
<B>
|
||
|
|
Note: The script <i>test_zoltan</i> as described below is obsolete.
|
||
|
|
It will work in some instances, but is no longer generally supported.
|
||
|
|
<p>
|
||
|
|
Automated testing is now supported through CMake. Build
|
||
|
|
<a href="../ug_html/ug_usage.html#CMake">Zoltan
|
||
|
|
through CMake</a> with option
|
||
|
|
<blockquote>
|
||
|
|
"-D Zoltan_ENABLE_Tests:BOOL=ON"
|
||
|
|
</blockquote>
|
||
|
|
<p>
|
||
|
|
Automated tests can be then run with command
|
||
|
|
<blockquote>
|
||
|
|
make test
|
||
|
|
</blockquote>
|
||
|
|
The testing environment uses script <i>zoltan/test/ctest_zoltan.pl</i>.
|
||
|
|
To add new <i>zdrive.inp</i> files to an existing test, add the files to
|
||
|
|
the appropriate directory and to the glob commands in <i>ctest_zoltan.pl</i>.
|
||
|
|
(Follow the example of <i>zdrive.inp.rcb</i> in <i>ctest_zoltan.pl</i>.
|
||
|
|
<p>
|
||
|
|
To add new test directories, create the directories and populate them
|
||
|
|
with input files. Copy file <i>CMakeLists.txt</i>
|
||
|
|
from <i>zoltan/test/ch_simple</i> to the new directories,
|
||
|
|
and edit the test names and numbers of processors in the new files.
|
||
|
|
Also add the new directories to <i>zoltan/test/CMakeLists.txt</i>, following
|
||
|
|
the example of <i>ch_simple</i>. The new tests will now be run in the CMake
|
||
|
|
environment.

<p>

The purpose of the Zoltan test script is to run the test driver <i><a href="dev_driver.html">zdrive</a></i> (or
|
||
|
|
<i><a href="dev_driver.html">zfdrive</a></i>)
|
||
|
|
on a set of test problems to verify that the Zoltan library works correctly.
|
||
|
|
The script compares the output of actual runs with precomputed output.
|
||
|
|
The assumption is that if the outputs are identical, then the current implementation
|
||
|
|
is is likely to be correct.
|
||
|
|
Small differences may occur depending on the architectures used; developers
|
||
|
|
should examine the output and use their judgement in determining its correctness.
|
||
|
|
It is strongly recommended that developers
|
||
|
|
run <i>test_zoltan</i> to verify correctness before committing changes
|
||
|
|
to existing code!

<h3>
|
||
|
|
How to run <i>test_zoltan</i></h3>
|
||
|
|
First make sure you have compiled the driver <i><a href="dev_driver.html">zdrive</a></i> (or <i><a href="dev_driver.html">zfdrive</a></i>).
|
||
|
|
Then go to the Zoltan directory <i>Zoltan/tests</i> and type<i> test_zoltan </i>
|
||
|
|
with suitable options as described below. This will run the test script
|
||
|
|
in interactive mode. The output from the driver will be sent to <i>stdout</i>
|
||
|
|
and <i>stderr</i<i>stdout</i>
|
||
|
|
and <i>stderr</i>
|
||
|
|
with a summary of results. The summary of results is also saved in a log
|
||
|
|
file. If an error occured, look at the log file to find out what
|
||
|
|
went wrong. The script currently assumes that runs are deterministic
|
||
|
|
and reproducible across all architectures,
|
||
|
|
which is not necessarily true.
|
||
|
|
Hence false alarms may occur.

<h3>
|
||
|
|
Test problems</h3>
|
||
|
|
The test problems are included in subdirectories of the <i>Zoltan/test</i>
|
||
|
|
directory. Problems using <a href="http://cs.sandia.gov/CRF/chac.html">Chaco</a> input files are in subdirectories
|
||
|
|
<i>ch_*</i>; problems using Nemesis input files are in subdirectories
|
||
|
|
<i>nem_*</i>.
|
||
|
|
Please see the README files located in each test directory for more
|
||
|
|
details on these test problems.
|
||
|
|
<h3>
|
||
|
|
Load balancing methods</h3>
|
||
|
|
Many different load-balancing methods are currently tested in <i>test_zoltan</i>.
|
||
|
|
Input files for the methods are found in the test problem subdirectories.
|
||
|
|
The input files are named <i>zdrive.inp.<method></i>, where <i><method></i> indicates which load-balancing method is passed to Zoltan.
|
||
|
|
To run only a subset of the methods,
|
||
|
|
edit the <i>test_zoltan</i> script manually; searching for "rcb" shows
|
||
|
|
which lines of the script must be changed.
|
||
|
|
<br>
|
||
|
|
<h3>
|
||
|
|
<b>Number of processors</b></h3>
|
||
|
|
The script <i>test_zoltan</i> runs each test problem on a predetermined number of processors, currently
|
||
|
|
ranging from 3 to 9.
