The UGent researchers have access to the following infrastructure: https://www.ugent.be/hpc/en/infrastructure.
At this moment there are 2 clusters with GPU computing: joltik and accelgor. A complete guide to the HPC can be found here https://docs.hpc.ugent.be/Linux/linux-tutorial/
Goto https://account.vscentrum.be/ and upload your RSA key (it should be in ~/.ssh). See SSH key if you have no ssh RSA key.
Wait until you get a confirmation e-mail. (more info @ https://www.ugent.be/hpc/en/access/policy/access)
Use the ssh command from your terminal to log into the head node:
ssh {vsc_account_number}@login.hpc.ugent.be
replace the {vsc_account_number} you have been appointed eg. vsc40678@login.hpc.ugent.be.
Type exit to end the HPC ssh command line session
You can check your quota on the account page https://account.vscentrum.be/. If you are not careful, you will quickly fill up your home account, it’s only 3GB! However you have 2x 25GB in the $VSC_DATA and $VSC_SCRATCH folders. Login into the HPC and make them available with links:
ln -s $VSC_DATA data
ln -s $VSC_SCRATCH scratch
It’s also a good idea if you move the .cache folder to you scratch folder now:
mkdir .cache 2>/dev/null
mv .cache scratch
ln -s scratch/.cache
You can easily use sftp to transfer files to and from the HPC cluster.
From your computer to the HPC scratch folder:
sftp {vsc_account_number}@login.hpc.ugent.be
cd scratch
put {file_from_your_computer}
quit
From the HPC data folder to your computer:
sftp {vsc_account_number}@login.hpc.ugent.be
cd data
get {file_from_hpc}
quit
