Results Directories

Next are folders and files generated by each format.

backward

Includes files for backward propagation at each number of time steps defined in the call back configuration show_each=200

forward

Includes files for forward propagation at each number of time steps defined in the call back configuration show_each=200

reverse

Includes files for reverse propagation at each number of time steps defined in the call back configuration show_each=200

  • In case of 2 propagation:it will include the reread data of forward propagation.

shots

Includes files of the correlation result of each shot separately.

stacked_shot

Includes files of the stacked correlation result of consecutive shots. * stacked_correlation_0.bin: The correlation of the first shot only * stacked_correlation_1.bin: The stacking of the correlation results of the first and second shots.

traces

Includes files of the traces of each shot with some modifications if applied.

traces_raw

Includes files of the raw traces of each shot without any modifications .

velocities

Includes files of the forward and backward velocity with boundary extension for each shot.

migration.*

The final migrated values in the regarded format.

velocity.*

The used velocity model with boundary extension in the regarded format.

CSV

  • .csv: (comma-separated values) file format of the output folder.
  • To enable it make "enable": "yes" for "csv" in callback configuration.

Images

  • .png file format of the output folder.
  • To enable it make "enable": "yes" for "image" in callback configuration.
  • Can only be enabled if OpenCV is used and "enable": "yes" for "image" in callback configuration.

SEG-Y

  • .segy file format of the output folder.
  • To enable it make "enable": "yes" for "segy" in callback configuration.

SU

  • .su file format of the output folder
  • To enable it make "enable": "yes" for "su" in callback configuration.

Binary

  • .bin file format of the output folder.
  • To enable it make "enable": "yes" for "binary" in callback configuration

Others

filtered_migration.segy

The .segy format of the final migration after applying some filters to it.

timing_results.txt

Timings of different functions, also include Gpts/s , GB/s , Gflops/s of the different kernels.

norm

Includes the norm values for the forward, backward and reverse propagation in .tsv (Tab Separated Values) format.

Timing

  • Supported values for equation order : second | first
    • First wave equation timing in 2x of second wave equation.
  • Forward collector possible values : two | three | two-compression
    • Three:
      Is the fastest approach in timing.
    • Two:
      Is the slowest one as it depends on th I/O of the machine.
    • Two-compression:
      Timing is intermediate between three and two and also depends on the I/O and compression used.
