I work at the Renaissance Computing Institute where I help researchers from a variety of scientific disciplines to access very large scale computing resources via the Open Science Grid. The OSG is the United States’ component of the Large Hadron Collider (LHC) experiment’s compute fabric.

The work described here is largely about techniques for executing Open Science Grid computational workflows including the use of tools such as:

    • The Engage Virtual Organization (VO) submit host
    • GlideinWMS
    • Pegasus WMS

I’m also interested in emerging massively parallel architectures such as GPUs and especially in their use in large scale heterogeneous compute clusters such as the OSG.

In practice, this involves using infrastructure and tools including

    • Python with Django and ModWSGI
    • JQuery and JQuery-mobile
    • RabbitMQ
    • Java
    • Continuous integration with Hudson, OpenGrok and Nexus
