renamed the existing read_mesh_for_init() to read_mesh_for_init_ADIOS(), and created a new one called read_mesh_for_init() for the non-ADIOS case
added a link to the GitHub discussion about tomography tools
better compiler options for Portland pgfortran
revert pgfortan to pgf90 (although in principle pgfortan is the standard name these days, but it seems to break BuildBot)
got rid of compiler option -Mipa=fast,inline for pgf90 because it creates problems with some older versions of that compiler
changed pgf90 back to pgfortran, since the problem detected by BuildBot was not coming from that
framework for the future broadcast of the mesh and model databases in the case of simultaneous runs for the same mesh and model (but different source and/or receivers)
Merge pull request #235 from komatits/devel

framework for the future broadcast of the mesh and model databases in the case of simultaneous runs for the same mesh and model (but different source and/or receivers)
committed a change I had forgotten to make in my previous commit
updates get_cmt() and get_force(); only master process reads in source files
updates configuration and m4/ scripts
updates cuda file includes
added option to broadcast the database between simultaneous runs for identical mesh and model (but different source and/or receiver).
Merge pull request #237 from komatits/devel

added option to broadcast the database between simultaneous runs for identical mesh and model (but different source and/or receiver).
added test of size(array) > 0 before broadcasting them (arrays of size 0 are legal in Fortran for some reason, but can create problems in the call to our broadcast routines because we call them with array(1) as argument). Swapped two "use module" statements in src/specfem3D/fault_solver_*.f90 because the first used the second, which led to an internal compiler error with some versions of GNU gfortran.
added a more precise comment about the new option BROADCAST_SAME_MESH_AND_MODEL
moves summation, smoothing and model update tools of global versions from ADJOINT_TOMOGRAPHY_TOOLS/iterate_adj/cluster/ to SPECFEM3D_GLOBE/ package
solves merge conflict in serioal.f90
