REQUIREMENTS:
- ADIOS 1.5.0: http://www.olcf.ornl.gov/center-projects/adios
- C compiler
- MPI
BUILD:
- Install ADIOS
- In Makefile, set ADIOS_DIR to the installation directory
- also set the MPI/C compiler name (e.g. mpicc or cc)
- run make
This example is for writing a triangular unstructured mesh and data on it.
n = number of processes
Processes write data on 2(n-1) triangles per process
N is data on the points (value = rank)
C is data on the cells (value = rank)
1. Run the writer
=================
$ mpirun -np 4 ./triangle2d
2. Check the output
===================
integer /nproc scalar = 4
integer /npoints scalar = 20
integer /num_cells scalar = 24
integer /lp scalar = 8
integer /op scalar = 0
integer /lc scalar = 6
integer /oc scalar = 0
integer /cells {24, 3} = 0 / 19 / 9.5 / 5.058
real /points {20, 2} = 0 / 4 / 1.85 / 1.18533
double /N {20} = 0 / 19 / 9.5 / 5.02494
double /C {24} = 0 / 23 / 11.5 / 6.92219
$ bpls -l triangle2d.bp
triangle2d.n4.png is a plot of how the data N[20] over the 20 points should look like if visualized.
