Hello to all,

I've update CRX, this update is not "visible" on the user interface, but it will improve machine learning process ( METEO / PROPAGATION part ).

I've add a statistics caching system, witch improve the execution time of learning process ( call training in machine learning ).

This cache will normally divide the time by 5 ! 
I wait now the end off first exuction process to see the benefit on the next IA launch.

Hello to all,

Prediction propagation tool is now online after a long work starting in june 2018, you can use it via the button "METEO" and PREDICT button.

This tools is based on Machine Learning program, it run with dxcluster spots data and NOAA data ( solar flux, k/a planetary index). It's can be used to study the MUF.

I've take a long time to put it online, because, i test a lot of algorithm and i've to wait NOAA history data of 5 to 6 month for the algorithm to be efficient.

Reconstruction du cluster MYSQL GTID Actif/Passif
Date : 17/10/2018

MARIADB 10.1
DEBIAN 9.5

root@crx-hyp01 ~ # cat /etc/mysql/mariadb.conf.d/50-server.cnf  | grep id | grep -v 'pid'
gtid-domain-id  =       1
server_id       =       1

Le serveur crx-bck01 ne rempli plus correctement son rôle de serveur SLAVE MYSQL (erreur de réplication MYSQL);
Et le serveur crx-hyp01 est le serveur MASTER MYSQL.
