pdlf_reloc

A set of functions to compute time-delays and perform dd relocation. It's a work in progress (meaning, it is not yet working).

Dependencies

• python3 (not tested on python2 but should work)
• A functional MPI 1.x/2.x/3.x implementation like OpenMPI or MPICH built with shared/dynamic libraries

Python modules:

• numpy
• scipy.signal
• h5py
• matplotlib.pyplot
• pyproj

Download the package

To get everything, use the following git command:

git clone https://github.com/eost/pdlf_reloc.git

or download the module directly from https://github.com/eost/pdlf_reloc.git

Define clusters

First compute the correlation matrix using

mpiexec -n NPROC python cc_matrix.py

where NPROC is the number of CPUs that will be used to compute correlation coeffixients (should be at least 2: 1 process for the boss and at least 1 worker).

Then define clusters using

python define_clusters.py

Compute time-delays

Input parameters are indicated in Arguments.py

There are two possibilities to compute time-delays:

1/ Use an MPI version of the script to compute time-delays on multiple CPUs:

mpiexec -n NPROC python dt_computation_mpi.py

where NPROC is the number of CPUs that will be used to compute delays (should be at least 2: 1 process for the boss and at least 1 worker).

2/ Use a sequential version of the script to compute time-delays:

python dt_computation_cc.py

DD reloc

Use:

python ddreloc.py
