*Postdoctoral position in petascale expansion of superparameterized
climate simulation for understanding low cloud / climate feedbacks*
Department of Earth System Sciences
University of California, Irvine, CA
I'm looking for a computationally talented postdoc to join an exciting
new effort to better understand global low-cloud climate feedbacks using
petascale computers. Low clouds have been a decades-long
parameterization challenge for global climate models, and low cloud
feedbacks are a primary source of uncertainty in climate projections for
the 21st century.
You would join a new team - spanning UCI / UW / Stony Brook & PNNL -
that has envisioned a way to simulate low clouds globally with minimal
approximations. Our strategy hinges on re-engineering a multi-scale
(superparameterized) climate model to take advantage of the huge power
at the GPU-accelerated petascale on DOE's newest supercomputer systems.
By exploiting this technology we think it's already possible to make a
global model that heterogeneously resolves the small (250-m) scale
turbulent eddies that form boundary-layer clouds and that this would
lead to more robust simulations of low cloud-climate interaction physics
than has been possible.
The successful applicant would lead an effort at UCI to add a
petascale-capable MPI parallel decomposition scaffold to the
SuperParameterized Community Atmosphere Model v.5 (SPCAM5) so it can
scale to over fifty thousand processors. Only by running at these scales
can our project make the extreme computational demands of global low
cloud physics explicitly tractable over the entire planet. I would help
closely with the software engineering and design plan. Other
responsibilities will include optimizing the representation of simulated
low clouds in the new model against observations and applying it to
learn about the physics of global low cloud-climate feedbacks and
aerosol indirect effects on climate change.
As a central part of the team there will be leadership opportunities for
coordination and scientific interaction with expert collaborators at the
University of Washington (Chris Bretherton's group), Stony Brook
University (Marat Khairoutdinov's group) and the Pacific Northwest
National Lab (PNNL; Minghuai Wang & Balwinder Singh) who are working on
complementary software engineering activities including graphical
co-processor acceleration with GPUs and physics algorithm efficiency gains.
The term of appointment is for one year at first but with expected
renewal for as many as two more pending approval. Start dates are
flexible and could begin as early as September 2014. Due to the
computational needs of this project, strong software fluency in
Fortran90, MPI parallelization, standard UNIX scripting languages and
experience working in high performance computing environments are
required. Experience with modern versions of the Community Atmosphere
Model is desired but not essential. Salary will be commensurate with
experience and competitiveness.
Please submit electronically: (1) a curriculum vitae, (2) a publication
list, (3) a brief cover letter (no more than 1 page) describing research
interests and technical background, and (4) the names of four
individuals who can provide a letter of reference. Applications received
prior to August 1, 2014 will be given preference. Applications or
informal inquiries can be sent directly to me at mspritch at uci.edu
