When railroad tracks were first laid across the western U.S., there were eight different gauges all competing to dominate the industry – making a nationwide, unified rail system impossible; it took an act of Congress in 1863 to force the adoption of an industry standard gauge of 4-ft., 8-1⁄2 inches.
FedEx CIO Rob Carter believes the same kind of thing needs to happen for blockchain to achieve widespread enterprise adoption.
While the promise of blockchain to create a more efficient, secure and open platform for ecommerce can be realized using a proprietary platform, it won't be a global solution for whole industries now hampered by a myriad of technical and regulatory hurdles. Instead, a platform based on open-source software and industry standards will be needed to ensure process transparency and no one entity profits from the technology over others.
"I think we're in the state where we're duking it out for the dominant design," Carter said during a CIO panel discussion at the Blockchain Global Revolution Conference here. "We're not an organization that pushes for more regulatory control, but there are times regulatory mandates and pushes can be incredibly helpful."

I'm talking about "hierarchical data format" https://portal.hdfgroup.org/display/HDF5/HDF5 [hdfgroup.org] (this particular website seems to be somewhat broken, so I'm not sure the group is being administered properly at the moment, but the library is nonetheless extensively used in scientific computing).
And MPI refers to "message passing interface" https://en.wikipedia.org/wiki/Message_Passing_Interface [wikipedia.org] .
I've personally encountered situations where a simulation crashed without closing the HDF5 file properly, and a lot of data became unreadable, including parts of the file that were not being written to (individual files are organized more or less like a filesystem themselves, this is why I can clearly identify what was being written to or not).
I was wondering whether tracking read/write operations properly would help with data recovery.

Ok so for something like this a journal would provide superior results especially if the journal is also storing a hash of the resulting file to ensure integrity.
The difference here is that yes you're using hashes to ensure integrity, but you don't care so much about the source, no particular node in the system would have any more or less "permission" to make changes to the journal or the filesystem. Thus you don't need to verify the chain of custody on the information, so a blockchain would be overkill.
A merkle chain vis a vis git would reduce performance, but would solve your integrity issues.
