A few bux fixes:

  • It looks like redefining the communicator as oops::mpi::world() was an issues. The comm is now using the one defined in Application and was added as a data member of NetCDFToIodaConverter.
  • Pointing to eckit's gather instead of oops'
  • A bit of code tidying

This worked with the 5 RADS files that I have, which is a change from "not working", but the obs count is quite low at ~200,000. We'll declare victory when we successfully test with the other observations.

@guillaumevernieres So this means we should be able to test with multiple input files?

@AndrewEichmann-NOAA , yes, but my tests started hanging in the gather again last night ... Same code. I added a few barriers and it started going through again, but that doesn't make any sense. I thought I found the bug, but looks like not!
I'll push my last commit but my next step is to workout a more robust serial implementation next.
