inversion using the tephra2 forward model and the downhill simplex method
To run the inversion model, at the command line, type:
mpirun -np nodes -hostfile machines tephra2-inversion_2020 tepha2-inversion.conf data_file wind_file
where,
- mpirun is the wrapper script for gcc when using mpi libraries
- nodes is the number of cluster compute nodes to use
- machines is a text file listing the name of each compute node and the number of cpu cores useable on that node (an example)
- tephra2-inversion_2020 is the executable name
- tephra2-inversion.conf is the file of parameters (an example)
- data_file is a text file of tephra accumulation data from chosen area (an example) following the format:
Easting(m) Northing(m) Grid-elevation(m) Mass(kg/m^2) - wind_file is a text file of wind data to use for the inversion
