Laboratories and Facilities of the Department of Physics<br />
F2. APE Laboratory<br />
The APE group is involved in research and development of High Performance Computing Architecture dedicated to<br />
theoretical physics applications (LQCD Lattice Quantum Chromodynamics, complex systems,...). Several generations of<br />
parallel supercomputers, known as ”APE machines”, have been built from the middle of 80’s. The last APE supercomputer,<br />
APENEXT is installed in our department from 2006 and it shows a peak performance equal to 10 TeraFlops.<br />
The APE group is currently composed of 4 staff<br />
people and 6 junior researchers with expertise ranging<br />
from hardware and software design to scientific<br />
applications coding and optimization. Current research<br />
activities focus on development of low latency<br />
and high bandwidth interconnection network<br />
for PC cluster (APENet+, 3-Dimensional Toroidal<br />
network optimized for LQCD computing platform),<br />
efficient use of (GP)GPU accelerators in theoretical<br />
physics (QUonG project) and design of specialized<br />
microarchitecture and systems optimized<br />
for scientific computing. Furthermore group members<br />
participate with leadership roles to EU FP7<br />
project (SHAPES, EURETILE) in the area of embedded<br />
systems and high performance computing.<br />
The laboratory is equipped with storage and computing<br />
servers hosting CAD software to support<br />
ASIC and hardware design. Multiple high end PC<br />

clusters are also present to test and develop application<br />
software. A complete soldering station as well as test and measurement instruments, (high performances digital<br />
oscilloscope and logic analyzer) are used to test and verify hardware prototypes.<br />
