Level 1, Level 2, and Level 3 packages can be built independently of the applications and used in your own
codes if you wish. However, please heed this <span style="font-weight: bold;">warning:</span><br>
Given the number of modules and the combinatorically larger variety of
possible ways to combine them, we suggest that if you are new to this
game you can <span style="font-weight: bold;">save yourself a lot of frustration by checking out one of the application suites above</span>. <br>
<br>
Having said all that, the currently available Level 2 SciDAC modules are described and listed below:

QDP/C is the C implementation of the QDP (QCD Data Parallel) interface.
It provides for lattice wide operations as well as lattice wide communications
and uses the <a href="http://usqcd-software.github.io/qmp">QMP</a>,
<a href="http://usqcd-software.github.io/qio">QIO</a> and
<a href="http://usqcd-software.github.io/qla">QLA</a> libraries.

The BAGEL QDP module is used to produce some optimized linear algebra
routines for use by QDP++ on some machines such the QCDOC and the
BlueGene. It requires the 3rd Party <a href="http://www.ph.ed.ac.uk/~paboyle/bagel/Bagel.html">BAGEL Assemb
ly Generator</a>
package to work. If you wish to use the BAGEL Assembly Generator, you
have to Acknowledge its use in any future publications, see the <a href="http://www.ph.ed.ac.uk/~pabo
yle/bagel/Bagel.html">BAGEL Assembly Generator for details.</a> A word of <span style="font-we
ight: bold;">warning: </span>The
BAGEL Assembler Generator page hosts an old copy of the BAGEL QDP
module which is now out of date for recent versions of QDP++ despite
its seemingly recent version number of (1.4.0). Please use the version
linked to from here instead. <br>

QIO provides as suite of input/output routines for lattice
data. It contains the SciDAC LIME implementation. By default QIO uses <a href="http://usqcd-software.github.io/qmp">QMP</a>
for its parallel communications although it can also be built in scalar
mode in which case no communications harness is required.
