Performing I/O in a logical and coherent manner from disparate processes is not easy. It’s even more difficult to perform I/O in parallel. I’ll begin

The use of coarrays can be thought of as opposite the way distributed arrays are used in MPI. With MPI applications, each rank or process has a local array; then
