[CIG-ALL] SPECFEM3D_GLOBE Version 5.0.0 "Tiger" released

[Sue Kientz]

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).
