/* -------------------------------------------

• PARAVT - PARALLEL VORONOI TESSELLATION
• COMPUTE VT ON LARGE PARTICLE DISTRIBUTIOINS
• USING QHULL LIBRARY AND MPI.
• ALSO COMPUTE SEVERAL QUANTITIES AND OUTPUTS
• FOR ASTROPHYSICAL PURPOSES.

Check Changelog.txt for version changes.

Check userguide.pdf for detailed code parameters.

1-Download

https://github.com/regonzar/paravt

2-Compile

Requeriments: Platform: Any linux compatible. Tested on RHEL 6, Centos 6.4, Centos 7. Should work in any MPI implementation, tested with OpenMPI-1.6.5+

Set config.h parameters

make

After change config.h you should "make clean", then "make".

3-Run

mpirun -np <Ntask> paravt <Input_File> <Format>

<Ntask> = number of tasks, should be a power of 2 (i.e. 2,4,8,16,32...) Code run only under MPI and with Ntask >= 2 <Input_File> = file name of input data

<Format> = Input file format. 0 = Ascii 1 = Binary 2 = Gadget 3 = Rockstar

4-Output

Files with names <Input_File>.<EXT> where, <EXT> can be: den = density file vol = voronoi cell volumes nb = neighbor number and indices nb2 = neighbor data VT.<Task> = Qhull raw output of voronoi structure, one file per each <Task> grid = density grid vtk = VTK file of density grid for visualization porpuses grad = density gradient vectors
