HPC software tool for climate research: paper published

VORtech is an SME-partner in the LINC project funded by EC’s Marie-Curie ITN program. Hisham Ihshaish and Johan Dijkzeul from VORtech helped researchers in the LINC project to approach climate phenomena from a complex systems point of view. An HPC software tool Par@graph has been developed to analyze the very large climate networks.

In the paper, Par@Graph is presented, a software toolbox to reconstruct and analyze complex climate networks having a large number of nodes (up to at least 10⁶) and edges (up to at least 10¹²). The key innovation is an efficient set of parallel software tools designed to leverage the inherited hybrid parallelism in distributed-memory clusters of multi-core machines. The performance of the toolbox is illustrated through networks derived from sea surface height (SSH) data of a global high-resolution ocean model.
