Documentation for mpiFileUtils


mpiFileUtils provides both a library called libmfu and a suite of MPI-based tools to manage large datasets, which may vary from large directory trees to large files. High-performance computing users often generate large datasets with parallel applications that run with many processes (millions in some cases). However those users are then stuck with single-process tools like cp and rm to manage their datasets. This suite provides MPI-based tools to handle typical jobs like copy, remove, and compare for such datasets, providing speedups of up to 50x. The libmfu library simplifies the creation of new tools and it can be called directly from within HPC applications.
