Parallel File I/O (serial-ascii)

Writing unstructured data to a contiguous file using MPI I/O with offsets

Programming language(s): C++ ·
Programming model(s): MPI ·

A naive approach to file I/O in parallel software is for one process to sequentially read/write ASCII data to/from a single file (e.g. using the C fscanf and fprintf commands) with point to point communications to share the data with all other processes.
