Wed., Sep, 25, 3:00 PM EDT Greg Wilson Mozilla Foundation / Software Carpentry
Nirav Merchant http://software-carpentry.org/ Over the last 15 years, Software Carpentry has evolved from a week-long training course at the US national laboratories into a worldwide volunteer effort to raise standards in scientific computing. This talk explores what we have learned along the way the challenges we now face, and our plans for the future.
Wed., Sept 11, 3:00 PM EDT Ilya Baldin RENCI/Programmable Cloud and Networks: The ExoGENI Project Nirav Merchant ExoGENI

ExoGENI: Networked Infrastructure-as-a-Service (NIaaS) for Scientific Workflow Applications.ExoGENI is a GENI testbed  that links GENI to two advances in virtual infrastructure services outside of GENI: open cloud computing and dynamic circuit fabrics. ExoGENI orchestrates a federation of independent cloud sites (i.e. OpenStack and Eucalyptus sites) and circuit providers (i.e. NLR and Internet2) through their native IaaS API interfaces and links them to other GENI tools and resources.  In this talk, we will present our current efforts and capabilities to enable the execution of complex data-driven workflows across geographically distributed sites.  First, we will present the high-level capabilities and architecture of ExoGENI and the Open Resource Control Architecture (ORCA)software layer that powers ExoGENI.  Second, we will describe the advanced virtualization mechanisms (SDN, storage, I/O) leveraged by our testbed that are crucial for efficient data sharing and processing. Finally, we will discuss our work toward the integration of our system with a state-of-the-art workflow engine (Pegasus) and  some interesting long-lived workflows currently running on ExoGENI. We will conclude with discussion on the future direction of our work.

Persephone: visualizing genomic data
Nirav Merchant
Webex Info

Recording of Presentation
Persephone™ is a software application for visualization and analysis of genomic data. It has been designed to display diverse data such as genetic maps, genomic sequences, gene models, synteny, QTLs, SNPs, RNA-seq, and gene expression. The application presents genomes as sets of maps. A map can be based on marker positions (genetic maps) or a genomic sequence (physical maps).The user can align maps of different types, which makes the application valuable for those who work with species that are not yet completely sequenced. Our technology allows zooming from a chromosome bird's-eye view down to the nucleotide level. The SNP track visualizes individual genotypes along with the reference sequence and assists in the derivation of haplotypes. The QTL search narrows a large volume of QTLs down to a filtered set of studies based on given criteria, such as target traits or treatments
2PM EDT, Monday, March 25 Brody Sandel, Aarhus University Patterns of Phylogenetic Diversity in New World Plants Martha Narro WebEx Info

Recording of Presentation
Large scale patterns of phylogenetic diversity are not well understood for most groups of organisms. This is in part because of data availability and computational limitations. Distributional and phylogenetic data are needed for large numbers of species, and even given these data, traditional computational methods often cannot accommodate the resulting large data structures. In this talk, I use the BIEN distribution and phylogenetic data for more than 80000 New World plants to overcome data limitations, and novel algorithms and analytical approaches to overcome computational limitations. The results are the first maps of phylogenetic diversity for such a large group of organisms over such a large geographic extent. These results can be used to understand the evolutionary origin of hotspots of plant richness.
2PM EST, Tuesday, Feb. 26 Brian Enquist, University of Arizona Toward a General Informatics Engine to Quantify Botanical Diversity at Large Scales Martha Narro WebEx Info The iPlant-BIEN collaboration has produced the TNRS, preliminary species range distribution maps for plants in the Americas, and, this summer, will release the BIEN 3.0 database which comprises the most comprehensive set of species observations and trait data for plants in the Americas.
