DeltaDB at IEEE BigData 2014

Peter Ivie will be presenting his work on the DeltaDB database model for time-varying schema-free data at the IEEE International Congress on Big Data in Anchorage. The DeltaDB concept is what underlies the query engine for the cctools catalog server.

Journal Paper on MAKER and Work Queue

Our paper on converting the MAKER bioinformatics analysis from MPI to Work Queue, done in collaboration with the Notre Dame Bioinformatics Laboratory was recently accepted for publication in the International Journal of Bioinformatics Research and Applications.

CCL Papers at CCGrid 2014

Three papers from the CCL were presented at the 2014 IEEE Conference on Cluster, Cloud, and Grid Computing in Chicago:

• Paul Brenner presented a regular paper,
  Opportunistic High Energy Physics Computing in User Space with Parrot which shows how we use Parrot to provide transparent access to complex software stacks without requiring a dedicated shared file system.
• Olivia Choudhury presented Accelerating Comparative Genomics Workflows in a Distributed Environment with Optimized Data Partitioning at the C4Bio Workshop. This paper explores various strategies for data partitioning in bioinformatics applications; showing that partitioning for parallel execution must be specialized to the objective of the underlying tool.
• Nick Hazekamp presented a poster, Expanding Tasks of Logical Workflows into Independent Workflows for Improved Scalability in which he demonstrated a technique for transparently parallelizing components of a Galaxy workflow using Makeflow.
