Popis: | In this work we present the design decisions and advantages for accomplishing cross mesh format checkpoint-restart in community code FLASH-X. AMReX and Paramesh are the two AMR mesh formats developed and supported by FLASH-X. We also highlight strong and weak scaling study of existing HDF5 I/O checkpoint writing along with new ideas and results (presented during talk) for utilizing heterogeneous compute architectures for improved I/O performance.
