LAComS – Laboratory for Advanced Computation in Seismology

DomůLAComS – Laboratory for Advanced Computation in Seismology

What is LAComS?

  • The acronym stands for Laboratory for Advanced Computation in Seismology
  • A free ad-hoc platform for colleague seismologists with the same/similar problems to help mutually with our computing challenges
  • It was established step by step between 2018-2020
  • Background idea of the platform: technical computing problems are usually not described in large details in (seismological) journals/articles, event if they sometimes may consume a lot of the effort / time spend on the problem

Examples of considered/relevant topics

  • Hardware problems (e.g. graphical cards connection suitable for computation)
  • Parallel computation / problems with algorithm parallelization
  • Computation on GPU units
  • Multiple CPU units computation, computer clusters
  • Modern software: AI/ML/CNN/RNN (artificial intelligence, machine learning, convolutional neural networks, recurrent neural networks)
  • Inversion problems (nonlinear, huge linear equations system)
  • Errors / reliability estimation
  • Way of advanced visualization (e.g. 3D data)
