Job submission

Jobs can be submitted through the command line, through the graphical job composer and by using interactive apps.

command line

TrinityX uses slurm as the default scheduler. Other schedulers are technically supported, however the documentation for the command line approach will cover slurm only.

Please consider visiting Slurm's extensive documentation and knowledge base.

Example job script test.slurm that incorporates the use of modules:

#!/bin/bash
#
#SBATCH --job-name=test
#SBATCH --output=results.txt
#SBATCH --ntasks-per-node=28
#SBATCH --nodes=2
#SBATCH --time=05:00
#SBATCH -p compute
#SBATCH --mail-type=BEGIN,END
#SBATCH --mail-user=test@cluster.lan

module load compiler/latest mpi/latest

mpicc mpi_hello.c -o mpi_hello

mpirun ./mpi_hello

submission:

sbatch test.slurm

Job composer

An alternative to command line submission would be the use of the Job composer provided by Open OnDemand portal.

Interactive apps

Another way is to use the interactive apps, which are launched through the scheduler. The application runs being a job, using requested resources.

Once an app is selected (clicked), a form appears that allow you to select the desired required resources. The launch will send the request to the scheduler.

The app will then be scheduled.

Once resources become available, the user can then connect to the app which will then be actually launched or started.
