MW: Submitted parallel IO FMS patch. New automake made PR more complicated. FMS now buildable by automake. If we add new files/dependency build will fail. Not very auto. Works well. Some tuning with lustre. Just need a good
io_layout with large contiguous chunks.
AH: Compression? MW: IO runtimes double with compression. Testing some of the newer algos and getting better numbers. AH: How does he get other compression into netCDF? MW: Custom libraries. Will make accessible when time comes. Have been using it. Good. MW: Haven’t heard back from GFDL yet. AH: will be needed for further high res models.
MW: Issues with GNU/Intel. Dale roberts wooing on this. Also module versions are an issue. Intel 18 can’t read 19 mod files for example. Don’t think there are any includes. If there are, should be fixed. RF: There is include mpi.f. Not sure how they include netcdf.
