Reverse Time Migration for Uncertainty Quantification.

MAIN FEATURES OF THE FORMULATION

  • Physical and mathematical characteristics:

    -- Second-order wave equation

-- Isotropic acoustic medium

-- Invariant density

  • Numerical characteristics:

    -- Finite Difference Method (Second-order in time and Eighth-order accuracy in space)

-- Convolutional Perfectly Matched Layer for wavefield attenuation on the boundary

  • Image Condition:

    -- Cross-correlation: correlation between source wavefield and receivers wavefield. 

                      This process produces amplitude squared.

COMPILATION AND RUNNING INSTRUCTIONS

  • Compilation Requeriments:

    -- ICC compiler

-- OpenMP Library

-- MPI Library

  • Before Compiling follow the commands to build the ZFP library:

    -- cd ./ZFP_LIBRARY_0.5.5/build/
-- rm -r *
-- cmake -DBUILD_EXAMPLES=ON ..
-- make

  • Compilation:

    -- Use make file typing in the mais directory:

   make clean

   make

  • Local Running:

    -- Use the file "run_rtm_simulations.local":
   ./run_rtm_simulations.local

  • Cluster Running:

    -- Configure the file "jobRtmSimulations.job" as desired

EXTRA INFORMATION

  • For more details about input and output requirements see:

++ ./OUTPUTS/0_outputs_readme.INFO

  • To run this code, make download of the last version commited to a local repository.

  • The program is setting to migrate one seismogram on two rtm simulations.

    ++ See ./INPUTS/0_inputs_readme.INFO for more details.
