USQCD Software source code access

Source code access via CVS

There are several Lattice QCD source code packages available under CVS. Access is available to those who have JLab user accounts or via the exported tar-ball. There is also anonymous account access via CVS as well; however, there is no write capability back to the CVS repository via anonymous access.

There are several CVS modules one can access. The first column is the actual name to use for module name below:

• Application codes:

  • qmp: SciDAC QMP/C message passing interface
  • qmt: SciDAC QMT multi-thread package
  • qio: SciDAC QIO/C intermediate level input-output package
  • qla: SciDAC QLA linear algebra library
  • qdp: SciDAC QDP/C data parallel library
  • qdp++: SciDAC QDP/C++ data parallel library
  • qopqdp: SciDAC QOP high level operations library for QDP/C
  • chroma: Main production physics code over QDP++ using C++
  • bagel_qdp: Generates optimized code using the Bagel package
  • szin: SZIN code (over C/M4)

• Fitting codes:

  • adat: Analysis suite including support for Chroma
  • ensbc: Ensemble binary calculator
  • run_fit: Fitting code (perl drivers over fitmcosh)
  • fitmcosh: Fortran correlator fitting code

• Utilities:

  • c-lime: Binary file record archiver
  • nml: Namelist/parameter reading support
  • recode: Conversion (filter) from SZIN to QDP++
  • qdaemon: Cluster node/front-end daemon for executing parallel jobs

For those users with a JLab account, use

export CVS_RSH=ssh

for bash or sh or

setenv CVS_RSH ssh

for csh. Finally,

cvs -d :ext:<username>@cvs.jlab.org:/group/lattice/cvsroot checkout

and use your username at JLab.

Note, you can set the default CVS home with

export CVSROOT=:<...>@cvs.jlab.org:/group/lattice/cvsroot

and simply use

cvs checkout <module name>

For those users without a JLab account, you can retrieve the code via anonymous CVS access. However, one cannot make changes to the CVS repository.

One can simply under csh-like shells

setenv CVSROOT :pserver:anonymous@cvs.jlab.org:/group/lattice/cvsroot

cvs login

At the prompt, one supplies an empty password. Checkouts proceed as above:

cvs checkout <module name>
