[Lorraine Hwang]

8 May 2013

 

Dear CIG Community:

 

Attached is the CIG Quarterly Newsletter for May 2013.  The newsletter
features:

.         SPECFEM sustains 1 petaflop on Blue Waters;

release of 

.         SELEN 2; and

.         ASPECT 0.2.

 

We continue to actively soliciting both feedback on and contributions to
newsletter content.  In particular, contributions needed from the community
are:

.         Research Highlights

.         Recent Publications

.         Webinar Speaker suggestions

 

Newsletters will continue to be available for download through our website.

 

Please save Thursday, May 16 @ 2pm PT for our next CIG Webinar featuring
Nick Featherstone from HOA NCAR on Stellar Scalable Pseudospectral Methods
and the Geodynamo. His webinar will begin with a brief overview of recent
efforts to model convection and dynamos in the Sun and other stars. Such
models (massive stars in particular) share many fundamental aspects in
common with geodynamo models. Until recently, stellar dynamo studies that
employed pseudospectral methods involving spherical harmonics also faced the
same fundamental challenge as geodynamo models; scalability. After
describing how this obstacle has been overcome within the last year for the
Anelastic Spherical Harmonic code, he will present the essential elements of
a scalable pseudo-spectral framework (based on MPI) that CIG is now
assembling into a community dynamo model. He will conclude with some
thoughts on how this framework may be extended to incorporate GPUs and/or a
hybrid OpenMP/MPI approach. 

 
You may connect to the meeting through the link provided below or through
the home page at  geodynamics.org.  More complete instructions can also be

Remember to test your connection before the beginning the webinar.

 

Thanks,
