Which projects can I submit jobs to on abel?

Log in to abel and run

projects

You should see

cees
nn9244k

In addition to these two, you can also submit jobs to the (small!) 'uio' queue

'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 for the solution.
