Standard Output:

At the time of this test is written, I used the following libraries.
|

HDF5 version 1.8.10
|
||||
netCDF version 4.2.1.1 and
|
||||
PnetCDF version 1.3.1
|
||||
|
||||
If macro DISABLE_PNETCDF_ALIGNMENT is defined (i.e. disable PnetCDF
|
||||
alignment) then there is no standard output.
|
||||
|
||||
If macro DISABLE_PNETCDF_ALIGNMENT is NOT defined (i.e. default PnetCDF
|
||||
alignment) then this test reports unexpected read values below.
|
||||
|
||||
unexpected read value var i=1 buf[j=0]=0 should be 10
|
||||
unexpected read value var i=1 buf[j=1]=0 should be 11
|
||||
unexpected read value var i=1 buf[j=2]=0 should be 12
|
||||
unexpected read value var i=1 buf[j=3]=0 should be 13
|
||||
unexpected read value var i=1 buf[j=4]=0 should be 14
|

unexpected read value var i=3 buf[j=0]=0 should be 30

unexpected read value var i=3 buf[j=1]=0 should be 31
