The Taito supercomputer at CSC is at our disposal for performing
computational exercises. Material for the exercises can be found at
Taito under the following directory:
/appl/courses/Aalto_autumn_school_2016/
1. Transferring files to and from Taito
Using Windows, use SCP to transfer files between your workstation and Taito through these steps:
Launch the application "WinSCP"
Under "Host name", enter "taito.csc.fi"
Enter your user name and password into the designated fields
Click "Login"
2. Establishing an SSH connection to Taito
Using Windows, log onto the Taito supercomputer via SSH through these steps:
Launch the application "Xming"
Launch the application "PuTTYTray"
Under "Session", enter "taito.csc.fi" for the Host Name
Under "Connection" > "SSH" > "X11", select "Enable X11 forwarding"
Click "Open" and follow the instructions.
3. Running jobs on Taito
Move to your personal work directory via the command "cd $WRKDIR"
Calculations are performed by creating a batch job
script using a text editor and then submitting the job script to the
batch system. Do NOT run jobs directly on the login nodes.
Here's an example of a batch job script:
#!/bin/bash -l
#SBATCH -J my_jobname
#SBATCH -e my_output_err_%j
#SBATCH -o my_output_%j
#SBATCH --mem-per-cpu=2000
#SBATCH --constraint=hsw
#SBATCH -t 00:15:00
#SBATCH -n 4
#SBATCH -p parallel
#SBATCH --reservation=training
## run my MPI executable
srun my_executable
exit 0;
Submit your script using the command "qsub myscript.sh"
Check the status of your job using the command "qstat"
