Astronomy Colloquium Speaker Calendar

For decades, our community has enjoyed a relatively stable view of computing that has allowed simulation capabilities to flourish and yield a wide range of new insights.  That era has ended and new challenges have emerged that demand a fresh approach.  In this talk, I'll describe the paradigm shift already underway in the technology industry, give a high-level perspective on what to expect in the future, and discuss implications for doing astrophysics as a menagerie of hardware and software technologies emerge.  As an exemplar of a viable path forward, I'll describe the open source Parthenon project, a flexible, scalable, portable, and high-performance infrastructure for developing multiphysics codes using block-structured adaptive mesh refinement.  Finally, I'll describe a new open source code built atop Parthenon called Phoebus that we are developing to tackle a wide range of problems in relativistic astrophysics.
