How to request advanced reservations
An advanced reservation is the ability to submit a job such that it runs at a specified point in time in the future.
It has been decided as a matter of policy to restrict the usage of this and so it is available on request on a per-reservation basis by emailing firstname.lastname@example.org. You should look at the manual information for the command qrsub which will indicate how you would submit an advanced reservation request ordinarily and this will indicate the information you should provide in your request to the above email address.
A typical qrsub would be:
qrsub -a 1303080900 -d 12:00:00 -pe openmpi 512
Which indicated an opempi job with 512 slots to run. The parameter following -a is the data time specification:
date_time The date_time value must conform to [[CC]]YY]MMDDhhmm[.SS], where: e.g. CC denotes the century in 2 digits. YY denotes the year in 2 digits. MM denotes the month in 2 digits. DD denotes the day in 2 digits. hh denotes the hour in 2 digits. mm denotes the minute in 2 digits. ss denotes the seconds in 2 digits (default 00).
And the option after -d is the duration (HH:MM:SS format) and so the above would be a reservation for a 12 hour job.
There may be other options you would wish to add, e.g. the other mpi parameters selecting nodes or spreading jobs over nodes, and so on. Please check the manual pages on www.n8hpc.org.uk and http://n8hpc.org.uk/research/runningjobs/batchsystem/submittingjobs for details, or look at the qsub commands you are currently using or contact local support.
