GPU cluster at Heyrovský Institute

Data storage

Each user has access to three different storage. They differ by their capacity, backup and read/write speed.

Home directory

Each user has a home directory /home/<username>. It is physically located on the SSD in the login server and it is shared with all the computational nodes. Due to the overall performance of the cluster, it is recommended to open the files and read from / write to them only on the login node. Although it is possible, it is strongly discouraged to perform any operation on the files in the home directory from the computational nodes.

Use case example

A recommended way to use the home directory on the computational node in the job is following:

1. At the beginning of the job executed on the computational node, copy all the files necessary for the job execution from the home directory to the local partition on the execution node.
2. Perform all the calculations of the job reading and writing the files only from and to the local data partitions on the execution node.
3. After completing all the calculations of the job, copy all output files from the local execution node to the home directory.
