I've run into an issue when writing a parallel reader for partitioned files containing multi-block data. All data reads in fine on each process and works as expected, except for one thing. Since each partition only knows about the blocks it contains (and not the global blocks), I've not been able to have all the blocks available in the entire data-set available to the user. What I get instead is the list of blocks read in by the last data reader. I've got a couple of ideas to resolve this issue.
(1) Have some sort of communication between each of the PV processes to ascertain which process has which data (2) Have the number of blocks stored on each process the same as the global number of blocks, but just allocate data to the blocks that each partition/process has data of. So, my questions are: (1) Is item (1) possible and, if so, what class(es) should I be looking at to do it (2) Will item (2) alone solve my issue, or will I run into problems whereby if block 0 has 50% of its data on partition 0 and the rest on partition 1 that, after reading in, I will only ever see 50% of block 0 being whichever of partition 0 or 1 is read in last.
