[Gmsh] Gmsh parallel delaunay algorithm (3d)

[Christophe Geuzaine]

Dear Andrew,

The results from the paper were obtained using a standalone prototype. This new parallel 3D algorithm is currently being integrated in Gmsh, but the work is not complete yet. We plan to make this available in Gmsh 3.0, hopefully this summer.

I have read this article (http://www.imr.sandia.gov/papers/imr24/01_IMR24_Remacle.pdf) and wanted to test speedup of gmsh implementation comparing to tetgen 1.5 and to my own implementation but faced some problems.

Am i right that gmsh implementation is not ready for parallel processing yet?
