By prior arrangement only, users may submit jobs that exceed limits to the specq. Users must contact the system's administrators through [castorc.support@cyi.ac.cy|mailto: castorc.support@cyi.ac.cy] to require to submit jobs in that special queue, justifying their request. Jobs submitted to the specq will be started running manually from the system's administrator.
{note}
# Jobs outside the above limits will not be able to run.
# It is not possible to run interactive jobs on the system, however once a job has started users can login to the nodes where their job runs.
# The cpub and gpub queues can be used only by users with no CPU and GPU quota left respectively. These queues have very low priority.
# Interactive jobs get one node and half hour walltime by default, if not specified. Users can run interactive jobs on Cy-Tera:
#* Monday-Saturday, 09:00-23:59
#* Sunday, 13:00-17:00

h5. Job Submission
To submit a job on Cy-Tera users have to specify in their script file to which queue the job must be submitted.
- For access to cpu nodes the following line must be added in the script file:
{code}
#PBS -q cpuq
{code}
- For access to gpu nodes the following line must be added in the script file:
{code}
#PBS -q gpuq
{code}
{info}
The above lines in the script file change according to the queue the job is submitted
{info}
\\
In addition, to submit a job on Cy-Tera *msub* is used instead of qsub. Hence, users have to type the command:
{code}
msub <script_name>
{code}
To submit interactive jobs on Cy-Tera users have to type the command:
{code}
msub -I -q cpui/gpui -l walltime=xx:xx:xx,nodes=y:ppn=z
{code}
The name of the queue must be specified, otherwise the job won't run.
