New Specfem3D_globe release
We are pleased to announce the release of SPECFEM3D_GLOBE Version 5.0.0 "Tiger".
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.
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.

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.
