HPC Cluster Aether

The LAMOS group is equipped with an HPC cluster, called Aether. The cluster is based on Intel's new Broadwell architecture and was installed in November 2016.

Specifications:

  • 56 compute nodes
  • dual Intel Xeon E5-2690v4 processors (2.6GHz, 14 cores)
  • 256GB (16 nodes) / 128GB (40 nodes) RAM
  • Intel OmniPath interconnect
  • 480TB BeeGFS parallel storage

Access

We are dedicated to maximize the usage of our HPC-cluster, and are happy to grant access to any interested person / working group at the University of Bremen, especially (but not limited to) MARUM and the natural sciences faculty (FB1). In order to get access, please contact the LAMOS-IT group.

IMPACT Infrastructure


LAMOS group, in collaboration with the DOAS group of IUP, developed an in-house prototype instrument, used in air-pollution studies. The novel imaging-DOAS (differential optical absorption spectroscopy) instrument IMPACT (Imaging MaPper for AtmospheriC observaTions, see fig. below) provides full-azimuthal pointing (360∘) with a large vertical coverage (∼41∘). Complete panoramic scans are acquired at a temporal resolution of ∼15 min, enabling the retrieval of NO2 vertical profiles over the entire panorama around the measurement site. This instrument has participated in two high visibility international campaigns (CINDI & AQABA).
