Laboratory of Computational Mathematics, Mathematical Software and Digital
Department of Mathematics, University of the Aegean
The Department of Mathematics of the University of the Aegean
has established a new laboratory on Computational Mathematics, Mathematical Software and Digital Typography.
The aim of this laboratory is, among other things, the support of the
scinetific community on issues related to Digital Typography and Mathematical Applications.
Other objectives of the laboratory are (among others)
to provide technical support for research in the
to support the teaching through publication of relative
material (printed or in electronic form)
the development and the aquisition of know-how on issues
relative to a Department of Mathematics
the development of mathematical software and the support
of open standards in the academic community
the research in the history of typography with emphasis on
Mathematics (as it developed in Greece and elsewhere).
System Architecture of Pythagoras
The high performance computing cluster named Pythagoras located in the Department of Mathematics of the
Aegean University is actually a Beowulf cluster. It consists of thirty two (32) processor cores available for computations
distributed in five (5) computing nodes and four (4) cores for managing the computing cluster (front-end node).
The five computing nodes and the front-end are interconnected through a GE switch which will be upgraded into 10GE switch
by the end of 2012 (funded by European NSRF). The operational environment of Pythagoras is the Rocks Cluster Distribution
(its development is supported by NSF of USA) on the CentOS Linux distribution. The used job scheduler is the Sun Grid Engine.
Both the OpenMP (Open Multi-Processing) programming model for Shared
Memory Programming and the MPI (Message Passing Interface) Programming
model for Distributed Programming are supported for the develpoment of
parallel and distributed algorithms and applications.
