QOPQDP

QOPQDP is an implementation of the SciDAC Level 3 QOP (QCD OPerations) API on top of the QDP/C library. The goal is to provide a complete reference implementation of the QOP API that is both portable to all platforms and at the same time well optimized for many platforms.

The QOPQDP package currently contains:

• Gauge:
  • Symanzik 1-loop force
• Asqtad:
  • dslash
  • inverter (single and multimass)
  • force
• Wilson:
  • dslash (with anisotropic clover)
  • inverter
• Domain Wall:
  • inverter

Current and past releases can be found here.

There is now a simple installer for SciDAC software packages called qinstall. Instructions for it's use can be found here.

*** NOTE: versions 0.11.0 and higher now require QDP version 1.8.0 or higher. Likewise versions before 0.11.0 require QDP versions before 1.8.0.

*** NOTE: as of version 0.9.0 the Asqtad inverter conventions have changed. See the README below for more details ***

The installation options can be found in the README file.
Information about software releases is available in the NEWS file.
You can also view the text and html versions of the ChangeLog.

The documentation for QOP is here.

The materials from the SciDAC 2007 tutorial are here.
Some simple step-by-step instructions for installing QOPQDP and all it's dependencies (QDP/C, QLA, QIO and QMP) can be found here here.

The motivation for this development comes from the U.S. Dept. of Energy SciDAC program. See the USQCD home pages for more details.
