Dear Bi Users,

The Slurm problem have been fixed!

The previous behaviour have been restored. Jobs that request node count
using only -N/--nodes now once again run one task per core by default.

We apologize for the delay. We could not fix this by changing the Slurm
configuration, but had to develop and test a patch for the Slurm source
code and this work took longer than expected.
