What are the plans to remove the 4Gb limit?

As per your support page

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.

Thank you!
