HI Peter, Thanks a lot. It seems to work. If I am understanding it correctly, having group size = MPI ranks, means that only proc 0 is reading the data and distributing it. Am I correct?
Is it possible to verify the size of elements / memory size after the file is read and before the partition to actually verify that only proc 0 is reading and storing before partitioning?
