Important change to Metview on ecgate

With this upgrade, use of the following 'metview commands on ecgate will be discontinued:  'metview_new', 'metview_old', 'metview_dev', 'metview_test', 'metview4', 'metview4_new', 'metview4_old', 'metview4_dev' and 'metview4_test'.  Users should use the module command instead to load the desired metview version as indicated in the table.

Discontinued Metview commandReplacement Metview command
metview_newmodule switch metview/new ; metview
metview_oldmodule switch metview/old ; metview
metview_devmodule switch metview/dev ; metview

metview4metview
metview4_newmodule switch metview/new ; metview
metview4_oldmodule switch metview/old ; metview
metview4_devmodule switch metview/dev ; metview

Using Metview in scripts running under cron

Users using /usr/local/bin/metview to pass the full path to the metview command in scripts run under cron will need to adapt their scripts and crontab entries to use a wrapper script which sets the environment before the script is run. This will ensure that the $PATH is set correctly and the 'metview' command is available for use directly in the script. For further information see Cron and time-critical jobs.

How to use the new versions for testing before the update of 15 June 2016

Users are strongly encouraged to test their software applications and data processing chain with the new versions of the various software packages before the date of the change to the default versions.

The new versions of the software packages can be selected by using the commands:

module switch metview/new

module load Magics/new

module switch emos/new

module switch grib_api/new

How to revert to the old versions in case of problems after the update of 15 June 2016

Users that experience problems with the new default software packages after the update of 15 June will be able to revert to the old default versions.  These can be selected with the commands:

module switch metview/old

module load Magics/old

module switch emos/old

module switch grib_api/old
