QUDA 0.7.0 released

[Mike Clark]

The QUDA developers are pleased to announce release 0.7.0, available at http://lattice.github.com/quda

It has been almost a year since the last official release of QUDA, and many new features have been added in the interim.  A summary of these new features (including bug fixes) are listed in the NEWS file (http://lattice.github.io/quda/quda-latest/NEWS).  Please report any issues at http://github.com/lattice/quda/issues (requires a GitHub account).

Enjoy!

QUDA: A library for QCD on GPUs

QUDA is a library for performing calculations in lattice QCD on graphics processing units (GPUs), leveraging NVIDIA's CUDA platform.  The current release includes optimized Dirac operators and solvers for the following fermion actions:

• Wilson
• Clover-improved Wilson
• Twisted mass (including non-degenerate pairs)
• Twisted mass with a clover term
• Staggered fermions
• Improved staggered (asqtad or HISQ)
• Domain wall (4-d or 5-d preconditioned)
• Mobius fermions

Implementations of CG, multi-shift CG, BiCGstab, and DD-preconditioned GCR are provided, including robust mixed-precision variants supporting combinations of double, single, and half (16-bit "block floating point") precision.  The library also includes auxiliary routines necessary for Hybrid Monte Carlo, such as HISQ link fattening, force terms and clover-field construction.  Use of many GPUs in parallel is supported throughout, with communication handled by QMP or MPI.

Several commonly-used packages integrate support for QUDA as a compile-time option, including Chroma, MILC, CPS, and BQCD.
