[en] Acoustic detection in ice is a promising method to investigate the low flux of ultra high energy neutrinos (E>10¹⁸ eV). Due to the long predicted attenuation length of acoustic waves generated by neutrino-induced cascades, a volume of several km³, as available in the polar ice cap, may be equipped with sparse sensors. In order to study in-situ the absorption, the refraction of sound and the background noise, the South Pole Acoustic Test Setup (SPATS), consisting of 21 pairs of sensors and transmitters organized in 3 strings, has been developed. Low temperature tests simulating the harsh South Pole environment and long range tests in an ice-covered lake have been undertaken. The results obtained demonstrate the robustness of the setup and allow a first estimate of the expected performance. A simulation showing the capability of the system concerning refraction and absorptivity of the ice is presented, together with the first results of the installed setup, which is planned to be deployed in the austral summer season 2006-2007.

[en] We report on the progress and status of the integration and test of APEmille, a SIMD parallel computer optimised for Lattice Gauge Theory (LGT) with a peak performance in the TeraFlops range. After extensive development and testing of the design, a first 128-node system has quickly and successfully been integrated. Tests with physics production runs are to be started soon
