Howdy,
I have been using netcdf-c-4.3.1.1 (with a pnetcdf bug fix) for my weather
model production runs, and just tried using 4.3.3.1 on a new system. I use the
netcdf-4 interface to create a pnetcdf file, for which I pass the 64-bit offset
bits:
cmode = ior(ior(NF90_PNETCDF,NF90_MPIIO),nf90_64bit_offset)
status = nf90_create(filename, cmode, ncid, comm = my_comm, info = my_info)
I found that the files were being created as just "classic", however.
Wei-keng Liao found the problem in libsrc5/nc5dispatch.c, which had this:
75 #if 0
76 cmode &= (NC_WRITE | NC_NOCLOBBER | NC_LOCK | NC_SHARE |
NC_64BIT_OFFSET);
77 #else
78 cmode &= (NC_WRITE | NC_NOCLOBBER | NC_LOCK | NC_SHARE );
79 #endif
which for whatever reason was clobbering the NC_64BIT_OFFSET bits. Is there any
reason not to always use the first line, i.e., change this to "#if 1"? This is
what I did, and it fixed the problem.
4.4.0-rc3 has the same issue in libsrcp/ncpdispatch.c (same line numbers).
Shouldn't the first line (with "| NC_64BIT_OFFSET") be the default?
Cheers,
-- Ted
