The idea is to allow the cpuset field in the database to store the id or many threads, e.g. 1+8 for thread 1 and thread 8. As a result the cpuset field in OAR database must be converted from Int to Varchar. This implies a database schema upgrade.

We have to check that code that changes or accesses the cpuset field will not break.

Also the job resource manager will have to make use of the cpuset field correctly.
