> We would like to announce the release of the first version of our Gstar
> package. Gstar is a simple collection of utilities and scripts which 
> will
> make working with the Grid (specifically Grid3 and OSG-ITB) much more 
> like
> a powerful UNIX workstation. The first utilities ready for general 
> testing
> are a powerful "foreach" of sites and information listed in GridCat. In
> the near future utilities which can help you manage your RLS namespace
> will be documented, cleaned up, and ready for use.
>
> We have provided a man page for the package, gstar(1), which attempts 
> to
> be the Gstar equivalent of UNIX intro(1). This man page provides a 
> brief
> introduction to the individual commands of Gstar (the majority of
> utilities have man pages as well).
>
> The majority of interesting things that can be done with Gstar, for 
> now,
> are done with grun(1). This command can expand various GridCat 
> variables
> contained within a command-line to be run on all sites or a specific 
> list
> of sites. An simple example to answer the question: How much $app disk
> space is my VO using?
>
> grun -c '/usr/bin/du -sh $app/ivdgl'

> The output is returned for each site listed in GridCat (small example
> output):

> # processing Vanderbilt, 6
> Vanderbilt: globus-job-run spike.accre.vanderbilt.edu/jobmanager-fork
> /usr/bin/du -sh /grid/grid3-app/ivdgl
>
> 177M    /grid/grid3-app/ivdgl
>
> # processing UFlorida-Grid3, 28 CPUs
> UFlorida-Grid3: globus-job-run ufgrid01.phys.ufl.edu/jobmanager-fork
> /usr/bin/du -sh /raid/data1/grid01/app/ivdgl
> 175M    /raid/data1/grid01/app/ivdgl
>
> The default is to run on jobmanager-fork for each site in the Grid3
> catalog. Our GridCat Perl module can be told to use OSG-ITB by changing
> the GSTAR_GRIDCAT_DB environment variable to the value of "osg".

> You can get the current Gstar package (v0.6) from:

>
> The Gstar Wiki, including documentation, can be found here:
> http://osg.ivdgl.org/twiki/bin/view/GriphynMainTWiki/GstarToolkit
>
> You will need to have the Perl DBI module and MySQL client available on
> the machine you run Gstar from. Information on installing these is
> available on the Wiki under the topic "troubleshooting". Installation 
> via
> Pacman is available and might be easier if you already have a local
