bugy 1.1.0

[Kui Gao]

Hi Lie-Quan,

         Please run "mpiexec -n 4 test_write test_double.nc". The test
assumes that the number is 4 in test/data/test_write.c.

         The ncdump of the resulting data file is as follows.

netcdf test_double {

// file format: CDF-1

dimensions:

        x = 100 ;

        y = 100 ;

        z = 100 ;

        time = UNLIMITED ; // (100 currently)

variables:

        double square(x, y) ;

                square:description = "2-D integer array" ;

        double cube(x, y, z) ;

        double time(time) ;

        double xytime(time, x, y) ;

 

// global attributes:

                :title = "example netCDF dataset" ;

data:

 

 square =

  0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20,

    21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38,

    39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56,

    57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74,

    75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92,

93, 94, 95, 96, 97, 98, 99,

...

}

 

         Thanks,

Kui.

Oops, I guess that I may not understand how to run test_double. 

Anyhow, the redef problem is true. Attached is the testing program to show
the probelm. Please help. Thanks.

Best regards,

Dear Parallel-netcdf Developers,

I really would like to use version 1.1.0 for its CDF-5 format in our
simulation. However, there are some issues (unrelated to CDF-5) in the
release 1.1.0. For example, the test_write program under test/test_double
failed to generated the right data file (as in test/data/test_double.nc).
Here is the ncdump of the resuting data file:

netcdf t {
dimensions:
    x = 100 ;
    y = 100 ;
    z = 100 ;
    time = UNLIMITED ; // (100 currently)
variables:
    double square(x, y) ;
        square:description = "2-D integer array" ;
    double cube(x, y, z) ;
    double time(time) ;
    double xytime(time, x, y) ;

// global attributes:
        :title = "example netCDF dataset" ;
data:

 square =
  0, nan, 2, nan, 4, nan, 6, nan, 8, nan, 10, nan, 12, nan, 14, nan, 16,
nan, 
    18, nan, 20, nan, 22, nan, 24, nan, 26, nan, 28, nan, 30, nan, 32, nan, 
    34, nan, 36, nan, 38, nan, 40, nan, 42, nan, 44, nan, 46, nan, 48, nan,

The testing environment is:
OS: Linux x64 (RHEL4)
Compiler: gcc 4.2.2
MPI: mpich2 1.0.7

Also, in my application, open an existing netcdf and add a new variable
(2-d) messed up the existing data somehow.  The same code works when
parallel-netcdf release 1.0.3 or early is used.
