pnetcdf nfmpi_put_vara_real_all problem

[Wong, David]

Hi Wei-keng,

     start and count have been declared as:

          NFMPI_OFFSET :: start(4), count(4)

I have tested in a smaller version of code and it worked. After I put it in our numerical model and it crashed. Any other thought? Please advise.

Cheers,
David

Hi, David,

Could you send us the code fragment or the program that can reproduce the error?

Just a reminder. The datatype of start and count must be integer*8.
Similarly, use integer*8 to define dimensions.
If you have done that already, there must be something else.
