cc-backend version 1.0.0
Supports job archive version 1 and database version 4.
This is the initial release of cc-backend, the API backend and frontend
implementation of ClusterCockpit.
** Breaking changes **
The aggregate job statistic core hours is now computed using the job table
column num_hwthreads. In a future release this column will be renamed to
num_cores. For correct display of core hours num_hwthreads must be correctly
filled on job start. If your existing jobs do not provide the correct value in
this column then you can set this with one SQL INSERT statement. This only applies
if you have exclusive jobs, only. Please be aware that we treat this column as
it is the number of cores. In case you have SMT enabled and num_hwthreads
is not the number of cores the core hours will be too high by a factor!
** NOTE **
If you are using the sqlite3 backend the PRAGMA option foreign_keys must be
explicitly set to ON. If using the sqlite3 console it is per default set to
OFF! On every console session you must set:
sqlite> PRAGMA foreign_keys = ON;
Otherwise if you delete jobs the jobtag relation table will not be updated accordingly!
