High-performance Computing

Clusters

The Genome Center Bioinformatics computing clusters consist of an ever evolving group of clusters collaboratively administered by the Bioinformatics Core Group housed at the UC Davis Genome Center. The clusters are utilized as a collective resource for serial and parallel applications that would be too computationally demanding for smaller research groups to implement. Where one researcher could purchase a small cluster in a grant and hire a system administrator to set it up, it is much more efficient to add computing power to existing infrastructure. This is where the Bioinformatics clusters come into play.

A few examples of large scale problems the clusters are regularly used for include:

  • Large Scale Sequence Alignment
  • Hidden Markov Model Development and Searches
  • 3D Molecular modeling
  • Mass Spec models
  • Phylogenetic inference
