<h3>CIG welcomes Louise Kellogg as our new Director, at our new UC
Davis home</h3>
<p>It is now official! CIG has a new home and a new Director. On
February 5 of this year, Louise H. Kellogg formally accepted the
Directorship of CIG, succeeding Michael Gurnis, who had ably served
since 2005 as our organization's first Director. As you know, Louise is
an acknowledged leader in the U.S. geodynamics research community and
is currently Professor of Geophysics in the Department of Geology at
University of California, Davis, as well as serving as director of the
KeckCAVES visualization facility there. She brings a broad level of
expertise to the job, not only in Geophysics but also in the areas of
high performance computation and high performance visualization. Please
join me in extending a hearty welcome and our best wishes to Louise. <i>-
Peter Olson, CIG Executive Committee Chair</i></p>
<h3>NSF funds CIG's Next Phase</h3>
<p>The National Science Foundation is preparing the Cooperative
Agreement that will serve as the contractual basis for CIG II, the
second round of our activities. In the meantime, CIG is in the process
of moving its headquarters from Pasadena to Davis, CA. Our new facility
will be located in the new Earth and Physical Sciences Building at UC
Davis, and will include access to high-performance computing,
visualization, and networking facilities. We are also in the process of
hiring technical staff members; recruiting announcements will go out
soon. We are looking forward to starting on Round II projects, once
these staff hires are completed. I am pleased to welcome CIG to its new
location, and I want to extend my deep appreciation to Mike Gurnis and
all the CIG staff who have worked to ensure a smooth transition for
CIG. <i> - Louise Kellogg, Director</i></p>
<h3>CIG Software Releases</h3>
<ul>
<li><b>SPECFEM3D GLOBE 5.0.1</b> - SPECFEM3D GLOBE simulates global
and regional (continental-scale) seismic wave propagation. The version
5.0.0 "Tiger" release contains a number of new features, including a
significant improvement in performance and a more accurate
implementation of the crust. The "Tiger" release also provides a
perfectly load-balanced mesh for 3D mantle models honoring shallow
oceanic Moho (depths less than 15 km) and deep continental Moho (depths
greater than 35 km). See the release notice at

for
full details. The latest update, version 5.0.1, includes new default
sedimentary routines, bug fixes, and further optimizations for regional
adjoint simulations. Visit

href="http://geodynamics.org/cig/software/packages/seismo/specfem3d-globe/">http://geodynamics.org/cig/software/packages/seismo/specfem3d-globe/</a>
for source code and manual. </li>
<li><b>SEISMIC CPML 1.1.0</b> - SEISMIC CPML is a set of eight
open-source Fortran90 programs to solve the two- or three-dimensional
isotropic or anisotropic elastic, viscoelastic or poroelastic wave
equation using a finite-difference method with Convolutional Perfectly
Matched Layer (C-PML) conditions, developed by Dimitri Komatitsch and
Roland Martin from University of Pau, France. Version 1.1.0 adds
support for viscoelastic or poroelastic media, which adds two more
programs to the package. A total of eight programs are now included.
See <a class="moz-txt-link-freetext"
href="http://geodynamics.org/cig/software/packages/seismo/seismic_cpml/">http://geodynamics.org/cig/software/packages/seismo/seismic_cpml/</a>
for
the source code and link to documentation. </li>
<li><b>SNAC 1.2.0</b> - SNAC (StGermaiN Analysis of Continua) is an
updated Lagrangian explicit finite difference code for modeling a
finitely deforming elasto-visco-plastic solid in 3D. In this update,
the base algorithm for remeshing has been changed and, as a result,
remeshing in SNAC has become more stable. Now SNAC can run for an
extended period of time, which would interest the long-term tectonics
community. The updated user manual also contains more information. On
the users' end, however, there is no visible change: input files for
the previous version can be used without modification.
See <a class="moz-txt-link-freetext"
href="http://geodynamics.org/cig/software/packages/long/snac/">http://geodynamics.org/cig/software/packages/long/snac/</a>
for source
code and updated manual. </li>
</ul>
<h3>Bug-Fixes</h3>
<ul>
<li><b>CitcomCU 1.0.3</b> - CitcomCU is a finite element parallel
code designed to solve, on a three-dimensional regional domain,
thermochemical convection problems relevant to the earth's mantle.
This release contains important bug fixes, see the release announcement
at <a class="moz-txt-link-freetext"
href="http://geodynamics.org/pipermail/cig-mc/2009-November/000191.html">http://geodynamics.org/pipermail/cig-mc/2009-November/000191.html</a>
for details. Users of previous releases are urged to upgrade to this
release. See <a class="moz-txt-link-freetext"
href="http://geodynamics.org/cig/software/packages/mc/citcomcu/">http://geodynamics.org/cig/software/packages/mc/citcomcu/</a>
for source code and documentation. </li>
<li><b>CitcomS 3.1.1.1 Manual Update</b> - CitcomS is a finite
element code designed to solve thermal convection problems relevant to
Earth's mantle. The manual was updated to fix the definitions of phase
change and the chemical Rayleigh number (the dominator was incomplete).
See <a class="moz-txt-link-freetext"
href="http://geodynamics.org/cig/software/packages/mc/citcoms/">http://geodynamics.org/cig/software/packages/mc/citcoms/</a>
for source
code and the updated manual. You can also run CitcomS on the TeraGrid;

<h3>CIG's TeraGrid Time Renewed; Use it to Try Out Codes</h3>
<p>Starting April 1, CIG received a renewal of its TeraGrid allocation,
and once again encourages U.S. researchers from the geodynamics
community to apply for blocks of time on TeraGrid machines. Sign up for
an allocation to benchmark codes or to try out CIG codes to see if the
TeraGrid can work for your research. To apply for some of CIG's
TeraGrid time, send in the application at

<h3>CIG Seismology Web Portal Processor Capacity Expanded</h3>
<p>The number of processors one can select when configuring runs on the
CIG Seismology Web Portal has been increased to 1014, as the portal now
uses TACC Lonestar's "hero" queue. The portal provides automated and
on-demand simulations, e.g., seismic wave propagation and synthetic
seismograms. This web site launches a simulation on remote TeraGrid
supercomputers using data gathered from various web sites and
databases, and returns the results to the user. Create an account and
login at <span class="link-https"><a class="moz-txt-link-freetext"
href="https://geodynamics.org/portals/seismo">https://geodynamics.org/portals/seismo</a>
</span>to run default and customized seismology simulations (click
"Accept this certificate..." when prompted).

<h3>Upcoming Workshops</h3>
<ul>
<li><b>2010 Workshop on Crustal Deformation Modeling</b>, June 14-18,
2010, Golden, CO. The Crustal Deformation Modeling (CDM) 2010 workshop
will focus on computational models addressing the seismic cycle across
single and multiple events. The workshop blends science talks on case
studies from particular faulting environments and on key rheological
behavior with discussions of current obstacles to crustal deformation
modeling. Get more details at

href="http://geodynamics.org/cig/workinggroups/short/workshops/cdm-10">http://geodynamics.org/cig/workinggroups/short/workshops/cdm-10</a></li>
<li><b>GLADE Workshop: From grains to global tectonics</b>, July
26-29, 2010, Scripps Institution of Oceanography, UC San Diego, CA.
GLADE (Geodynamics of the Lithosphere and Deep Earth) will serve as a
nesting ground for the U.S. Geodynamics community, and seeks to unify
the lithosphere and mantle dynamics communities to address outstanding
scientific and technical challenges in Geodynamics. July 29 activities
will include hands-on tutorials and demos for geodynamics software. We
strongly encourage participation from scientists investigating the
rheology of Earth materials and observing plate tectonic processes. Get
more details and register your interest at <a

</li>
<li><b>Training Session for the Gale Computational Software in
Tectonics and Geophysics</b>, to be held Oct 30, 2010, Colorado
Convention Center, Denver, CO (previous to 2010 GSA Annual Meeting). In
this training session, CIG will focus on training new users in the use
of the tectonics modeling software Gale, a 2D/3D parallel code that
solves problems in orogenesis, rifting, and subduction with a variety
of boundary conditions, including free surfaces and coupling to surface
erosion models. Get more details at

Marc Spiegelman for his work on behalf of the CIG community, especially
during this time of transition from CIG-I to CIG-II; Louise for
chairing the SSC and agreeing to lead CIG-II into the future; and
Laurent Montesi for his valuable contributions to the SSC. We also
