+====== Connection ======
+You need to use SSH applications (ssh, putty, winscp, mobaxterm) and Kerberos or SSH key authentication to connect to **HPC**.
+If **Kerberos** is used:
+  * Log in to the Linux environment in a VU MIF classroom or public terminal with your VU MIF username and password or login to **uosis.mif.vu.lt** with your VU MIF username and password using **ssh** or **putty**.
+  * Check if you have a valid Kerberos key (ticket) with the **klist** command. If the key is not available or has expired, the **kinit** command must be used.
+  * Connect to the **hpc** node with the command **ssh hpc** (password must not be required).
+If **SSH keys** are used (e.g. if you need to copy big files):
+  * If you don't have SSH keys, you can find instructions on how to create them in a Windows environment **[[duk:ssh_key|here]]**
+  *     Before you can use this method, you need to log in with Kerberos at least once. Then create a ''~/.ssh'' directory in the HPC file system and put your **ssh public key** (in OpenSSH format) into the ''~/.ssh/authorized_keys'' file.
+  *     Connect with **ssh**, **sftp**, **scp**, **putty**, **winscp** or any other **ssh** protocol supported software to **hpc.mif.vu.lt** with your **ssh private key**, specifying your VU MIF user name. It should not require a login password, but may require your ssh private key password.
+The **first time** you connect, you **will not** be able to run **SLURM jobs** for the first **5 minutes**. After that, SLURM account will be created.
+====== Lustre - Shared File System ======
+VU MIF HPC shared file system is available in the directory ''/scratch/lustre''.
+The system creates directory ''/scratch/lustre/home/username'' for each HPC user, where **username** is the HPC username.
+The files in this file system are equally accessible on all compute nodes and on the **hpc** node.
+Please use these directories only for their purpose and clean them up after calculations.
+====== PST eilės (partition) ======
+^Eilė (partition) ^Laiko limitas ^RAM	   ^Pastabos|
+^main             ^7d            ^7000MB  ^CPU telkinys|
+^gpu              ^48h           ^12000MB ^GPU telkinys|
+^power            ^48h           ^2000MB  ^IBM Power9 telkinys|
+Visose eilėse užduotims laiko limitas yra **2h**, jei jis nebuvo nurodytas, o lentelėje yra pateiktas maksimalus leidžiamas laiko limitas.
