GENOT NO. 016 EST LA VERSION FRANCAISE DE GENOT NO. 015.

MODIFICATIONS TO THE CMC REGIONAL FORECAST SYSTEM...

THE MODIFICATIONS DESCRIBED IN GENOTS FAX NO. 011, 012, 013 AND 
014 ISSUED AS NOCN02 CWAO 271930 BULLETINS LAST WEEK WILL NOT BE 
IMPLEMENTED ON TUESDAY, SEPTEMBER 1 1998.

TUNING OF THE MODEL RUNNING IN A MULTI CPU ENVIRONMENT LAST WEEK 
RESULTED IN A FEW INSTANCES IN WHICH THE MODEL COULD NOT COMPLETE 
ITS INTEGRATION OUT TO 48 HOURS AND HAD TO BE RESTARTED, THEREBY 
CAUSING UNACCEPTABLE DELAYS TO THE PRODUCTION.  THE SOLUTION TO 
THIS PROBLEM HAS BEEN FOUND, BUT IT WOULD BE PREMATURE AND UNWISE
TO IMPLEMENT THE NEW MODEL WITHOUT PROCEEDING WITH FURTHER TESTING
SO AS TO ENSURE A RELIABLE AND TIMELY DELIVERY OF PRODUCTS TO 
USERS.

WE WILL THEREFORE CONTINUE THE PARALLEL RUN FOR AN EXTRA WEEK WITH 
THE SOLUTION TO THE PROBLEM IN PLACE SO AS TO ENSURE THE 
RELIABILITY OF THE SYSTEM. 

IT IS LIKELY THAT WE WILL BE ABLE TO PROCEED WITH THE 
IMPLEMENTATION OF THE CHANGES DESCRIBED IN THE PREVIOUSLY 
MENTIONED GENOTS ON WEDNESDAY, SEPTEMBER 9 1998, AT 1200 UTC. WE 
WILL CONFIRMTHAT THIS IS THE CASE BY ANOTHER GENOT ON TUESDAY, 
SEPTEMBER 8.
