Hi Keith,
The modified wshist.F solved the problem and now the program can write
auxiliary data. Thank you.
Meanwhile another problem have appeared. When the model is run with the
default values of the MPI environment variables the program exits
abnormally with an error message to increase the value of
MPI_REQUEST_MAX (its default value is 1024). Just for test purposes I
set MPI_REQUEST_MAX to 100000, but the program exits again abnormally
with the message:
|> Insufficient request entries.
|> Please use MPI_REQUEST_MAX to increase your allocation.

I have small experience with ORIGIN2000/IRIX6.5 environment and I have
no idea what is the reasonable value for MPI_REQUEST_MAX and how to
increase the current limit of 16384. Is it possible that the model posts
16384 nonblocking messages without having them freed?
I will highly appreciate your opinion.
All the best,
Didi
