We are pleased to announce the release of SPECFEM3D_GLOBE Version
5.0.0 "Tiger," whose main new features are (1) a significant
improvement in performance, and (2) a more accurate implementation of
the crust. You can obtain the source code and latest user manual
through the CIG website at
http://geodynamics.org/cig/software/packages/seismo/specfem3d-globe
The new version 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). It also accommodates
European crustal model EuCrust07 (Tesauro et al., 2008), which may be
combined with global crustal model Crust2.0.
Additional new model routines are provided for generic point-profile
models (PPM) and Gauss-Lobatto-Legendre based models (GLL). The
structure of the software has been simplified to facilitate easier
implementation of new 3D models. The code accommodates general moment
tensor files, and provides more complete information in the SAC
headers, as explained in detail in the updated user manual.
New matrix-matrix multiplication routines, adapted from the book of
Deville et al. (2002), help reduce the total number of memory accesses
performed in each spectral element and thus significantly improve
performance.
Please e-mail your feedback, questions, comments, suggestions, and bug
reports to the CIG Computational Seismology mailing list (cig-seismo
at geodynamics.org).
