## 'Almost out of CPU hours' warning

When submitting a job to the slurm queue, you may see a warning similar to this one:

>  -- Warning: The specified project, nn9244k, is almost out of CPU hours, using 92% of CPU grant.
>     If you think this is incorrect, please contact us at [email protected]

Remember that when a job is set up for X CPUs for Y hours, the queueing system reserves X*Y hours for your job, even though it may take much fewer hours. All running and waiting jobs are counted towards the hours 'reserved'.
If you check with this command:

```
cost -p nn9244k
```

you will see that there are not enough hours 'available' for your job. This usually only happens at the end of an allocation period (March and September).

Solutions:

- set up your job so that it reserves fewer hours
- ask others to do the same
- switch to the 'cees' queue
- wait for the new allocation period (April 1st or October 1st)
- if it is still early in the allocation period, suggest we ask for more hours

## LC_ problems on MAC (e.g. LC_CTYPE)

Some of the MAC users experience a warning when logging in to abel mentioning LC_CTYPE or something similar. Please have a look [here](http://www.uio.no/english/services/it/research/hpc/abel/help/faq/#toc32) for the solution.
