Hi,
I'm using PDL-NetCDF 4.07 built with NetCDF version 4.1.1. I need to
create an output NetCDF file with more than 700 variables and the size
of the output file will be greater than 600MB. I can see that the
variables created (with put function) slower and slower and it may take
more that 13 hours to create the output file. This is just
straightforward to read (from another HDF file) and write process
without other calculations involved. I can see the program takes very
high (80-99%) cpu usage constantly with the 'top' command.
Any idea what's the problem and how to resolve it ?
Thanks,
Gary
