Before applying for this project please work through the exercise available on SPIN 2020 Exercise as this will be part of the interview with prospective candidates.

Exercise

...

...

  • run the example

...

  • shown in its README file.This will produce a directory Extrapolated_Strain with the output files in it

  • inspect the code in exercise.py and make sure you understand it, you can run it via:

    Code Block
    python3 ./exercise.py

    and it will create a file strain.h5 as the output.

  • it will show some data on screen to illustrate how to read HDF5 files
  • now edit the code to extract the final value for the quantitiy "qlm_coordspinz[2]" from file  "simulations/J0040_N40/output-0018/J0040_N40/quasilocalmeasures-qlm_scalars..asc"

    and add a new attribute "spinz" to the same dataset as "Mirr", output "spinz" similar to how "Mirr" is output

  • run the code and make sure that your output looks like this:

    Code Block
    languagetext
    Mirr is:  0.8849351497
spinz is:  0.622982178513881
strain is:  [[-1.07734394e+02 -1.97435367e-03 -3.47866610e-04]
