We take snapshots from time to time. We debated whether or not to update again for the 1.7 release, but ultimately decided not to do so - IIRC, none of our developers had the time.
If you are interested and willing to do the update, and perhaps look at removing the limit, that is fine with me! You might check to see if the latest ROMIO can go past 2GB - could be that an update is all that is required.
Alternatively, you might check with Edgar Gabriel about the ompio component and see if it either supports > 2GB sizes or can also be extended to do so. Might be that a simple change to select that module instead of ROMIO would meet the need.
Appreciate your interest in contributing!
How is the ROMIO code in Open MPI developed & maintained? Do Open MPI
releases take snapshots of the ROMIO code from time to time from the
ROMIO project, or was the ROMIO code forked a while ago and maintained
separately in Open MPI??
I would like to fix the 2GB limit in the ROMIO code... and that's why
I am asking! :-D
