How to use the new versions for testing BEFORE the update
| Tip |
|---|
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 may20 tag in modules. For example:
module swap metview/may20
module load Magics/may20
module swap eccodes/may20
module swap python/may20
|
How to revert to the old versions in case of problems AFTER the update
Users that experience problems with the new default software packages after the update will be able to revert to the old default versions. These can be selected with the commands:
module swap metview/old
module load Magics/old
module swap eccodes/old
module swap python/old
|
| Warning |
|---|
Please let ECMWF know if you need to revert to the old version of any of the packages after the update of the defaults has taken place. |
Change list
ECMWF Software
This table summarises the changes in the version of the different packages:
| Info |
|---|
ecCodes is now the official ECMWF encoder and decoder for GRIB and BUFR formats. It supersedes GRIB-API, for the GRIB format, and EMOSLIB, for the BUFR. If you still use any of those, we encourage you to migrate to ecCodes. |
Please see the Release notes for full details of the changes implemented in each package.
Third-party software
Some of the versions in this list may already be the default for a specific package on a certain platform, so no changes will be made in those cases. After the update, all platforms will have the same defaults for all these packages.
