Cadejos Supercomputer User Guide
Cadejos Quick Guide
There are 3 types of nodes in Cadejos: a login node (called meta), several compute nodes (called cadejos-i), and a development node (called vulcanus.cnca). All nodes share the same file system, but the compilers are only available on the compute and development nodes. Also, programs should be executed only on the compute nodes.
There are two ways to access the compute and development nodes: interactive or batch jobs. An interactive job lets the user directly access a node for some time window. A batch job executes a program on the first available set of nodes that satisfy the requirements of the program. Either way, all the jobs must go through a scheduler. The scheduler has 3 queues, dev for development and testing of your code, and n3h72 or n4h48 for actual runs. Cadejos uses PBS (Portable Batch System) to schedule the jobs. Here are some useful PBS commands.
- Submit an interactive job:
qsub -I -V -q dev -l nodes=1 -l walltime=00:30:00 - Submit an interactive job for development:
qsub -I -V -q dev -l nodes=vulcanus.cnca -l walltime=00:30:00 - Submit a batch job:
qsub script.pbs
where script.pbs is a file containing the PBS commands to run a program. For instance:
#PBS -N life
#PBS -q n3h72
#PBS -l nodes=1
#PBS walltime=0:30:00
cd $PBS_O_WORKDIR
./life 10 10 - Query the status of the jobs:
qstat - Cancel a job:
qdel <job_id>
