The Bianca Cluster

Bianca is a research system dedicated for analyzing sensitive personal data from large-scale molecular experiments. Bianca is part of the SNIC-SENS project.

Bianca provides each project with a virtualized "UPPMAX cluster environment" utilizing OpenStack as virtualization platform.

Bianca provides 3200 cores in the form of 200 dual CPU (Intel Xeon E5-2630 v3) Huawei XH620 V3 nodes with 128GB memory. Eight "fat" nodes have 256 GB or 512 GB of memory.

Reference datasets

We have the SweGen/1000 Genomes dataset as well as UKBB institutional genetics dataset. Available. See accessing swegen and our data page for details for requesting access.


Since Bianca is designed to handle sensitive personal data security is a key aspect of the configuration. In order to ensure that the data is safe we have implemented a series of security measures including, but not limited to:

  • One virtualized cluster per project, no resources are shared between projects.
  • Separate storage volumes per project.
  • Detailed logging of file transfers in and out of the cluster.
  • Two factor authentication
  • No internet access inside the clusters.
  • Locked racks for the hardware
  • Destruction of broken hard drives

Technical Summary

  • 200 compute nodes with dual CPUs and one 4TB disk
  • Each CPU has 8 cores
  • Total number of cores is 3200
  • Dual 10 Gigabit Ethernet for all nodes
