Parallel Processing Group, Department of Computer Science and Engineering, University of Ioannina, Ioannina, Greece
We maintain 2 servers which use apache2, dokuwiki, owncloud, and gitolite.
We also maintain 6 workstations, a couple of laptops and a custom 24-core machine which we use for development and experiments. These machines run various compilers such as GCC, Intel, and Oracle Suncc, debuggers/analyzers such as Intel vtune and development-related tools such as autotools, flex, and bison.
All are Debian-based for stability first (we always use STABLE) and for uniform administration. Debian was chosen because of stability and timely security updates.
