Release Notes for milestone 4
The Virtual Cluster liveDVD:
* provides tools and libraries that are installed and used at the partner sites.
* emulates the environment of the platforms available at HPC-Europa centers.
* allows hands-on building of a virtual cluster.

The liveDVD contains training and dissemination material published by the HPC-Europa2 project, including material from the partner centers such as slides, video tutorials and example code. Optional access to a source code repository enables the migration of code and data from the Virtual Cluster to the user account created on the HPC-Europa machines.

The liveDVD is based on SliTaz GNU/Linux, a free operating system, working completely in RAM and booting from a removable media. The file size of the SliTaz GNU/Linux 3.0 ISO image is 29 MB. Hence, it leaves plenty of space for adding tools, libraries and training material into this liveDVD. The SliTaz system is quick, responsive, and clean. A lightweight and elegant desktop is included as well in the 29MB ISO image.

The milestone4 ISO images has roughly the size of 3.4GB including several tools and libraries, as well as training material.

Νέο εργαλείο

Μετά από μερικά χρόνια χρειάστηκε να παρατήσω τον Γίγαντα (Giant Rock MTB) και να επιστρέψω σε μια σταθερή αξία της ελληνικής αγοράς. Ο λόγος για το νέο IDEAL PRORIDER, αν και μοντέλο του 2010, που μόλις μερικών ημερών φένεται να περνάει τις πρώτες δοκιμασίες επιτυχώς!
