What is the limit on the amount of data you can read in Parallel HDF5 ?
The limit is 2 GB because the MPI standard specifies that the 'count'
parameter passed to MPI_File_read() be a 32-bit integer.
1 Does this limit exist on ALL platforms? My experience (using Intel MPI)
is that there are no issues on Linux - the problem is only WIndows
2 What are the plans for you to fix this issue please, since is a
significant restriction of HDF5.
