Notes and Errata for the VL-e PoC 1.0 DVD Release

About the PoC 1.0 DVD Release

The PoC 1.0 DVD was released on April 7, 2006. It contains the all of the PoC 1.0 R1 software, as well as all the packages to install the LCG 2.7 middleware, and the SUN Java SDK, plus some additional packages that are required. This should be sufficient to install a complete LCG UI and the Vl-e PoC software.

This is the first official release of the PoC software, based on the list that was handed down by the VleIT. The software has been bundled as an apt-getable and yum-installable repository of RPM packages. This bundle can be installed on any Red Hat Enterprise Linux 3 compatible distribution.

The LCG 2.7 middleware is included on the DVD, but it should really be considered as a separate bundle. It is installed with YAIM. The PoC installer script will do this automatically.

The full set of the PoC software is obtained by installing one of two meta-RPMs, vl-e-ui for user interfaces or vl-e-wn for worker nodes (this is a subset without the graphical user interface tools). The installer will install the UI version.

The VL-e packages on the DVD are the same as the ones found on this website, but you should regularly check for updates of both the LCG middleware and the VL-e packages.

Installation instructions

Installation from the DVD is simple: open a terminal as root and run the dvdinstall install script (most likely found in /mnt/cdrom/dvdinstall). This will install an LCG UI and the vl-e-ui package, without asking a lot of questions.

Errata of the DVD

The autorun function on the DVD does not work in Windows.

Unfortunately, no unix2dos was used on the autorun.inf file on the DVD. Browser the DVD and open README.html in the doc directory.

LAM/MPI environment (Rpmi doesn't work without it)

The LAM/MPI software has been put in its own playpen: /opt/lam since it doesn't play nice with MPICH provided by LCG. To use LAM/MPI, you need to add /opt/lam/bin to your PATH variable, and /opt/lam/lib to LD_LIBRARY_PATH.
