Scalable scheduling of parallel iterative seismic jobs

#$%^&*AU2018274841A120181220.pdf#####ABSTRACT System and method for scalable and reliable scheduling of iterative seismic full wavefield inversion algorithms with alternating parallel (11) and serial (12) stages of computation on massively parallel computing systems. The workers are independent, initiating actions and unaware of each other, and given limited information. This enables application of optimal scheduling, load-balancing, and reliability techniques specific to seismic inversion problems. The central dispatcher specifies the structure of the inversion, including task dependency, and keeps track of progress of work. Management tools (23) enable the user to make performance and reliability improvements during the execution of the seismic inversion.*10 C-N toN ciN UN 0)N 0-N ciN enN -*N CN toNN CDN
