Hello. We would like to inform you of the management schedule and rules implemented this semester.

Please carefully review the new information, as it will be implemented starting this semester.

1. Active User and Alumni Survey (February 9 (Mon) ~ February 11 (Wed))

   Starting in the first semester of 2026, the Seraph server will undergo (1) the introduction of a Ceph Storage server (see attached information) and (2) the deletion of alumni accounts and directories.

   As previously announced in the second semester of 2025, the alumni account deletion will be applied to graduate students who graduated more than six months ago and undergraduate students (student ID starting with 2019 or lower).

   To select Active Users (heavy users with high server usage) for Ceph Storage allocation and alumni directory deletion, we will collect enrollment status from the following spreadsheet.

   1. If you entered a PhD program at your university after graduating from a master's program.
   2. If you entered a graduate program at your university after graduating from an undergraduate program.
   3. If you are conducting research in the 2026-2021 academic year (a separate application is required in this case. Link: link)

   If you fall into any of the three categories above, please access the spreadsheet and check your name.

   This survey will be conducted from Monday, February 9th to Wednesday, February 11th.

   If you do not respond to the spreadsheet after the survey, you will be considered alumni and will be excluded from the Active Users selection and your alumni account/directory will be deleted.

   After identifying graduates, we will provide further notice regarding the implementation of the Ceph Storage server and the deletion of graduate accounts/directories.

2. [Changed] Resource Upgrade and Affiliation Transfer Application (Application Period: February 19 (Thu) - March 6 (Fri))

   As with last semester, this semester's resource upgrade application will be processed via Google Forms.

   (The Google Form link will be provided during the subsequent application period.)

   Changes in affiliation, such as undergraduate → undergraduate research student and undergraduate research student → graduate school, will also be processed. Therefore, please use this form to apply for affiliation changes and cluster transfers other than resource upgrades.

   Request Period: March 9 (Mon) ~ March 12 (Thu)

   Upgrade Implementation: March 13 (Fri)

3. [New] Undergraduate Affiliation Integration and Dedicated Partition Implementation (Effective March 13 (Fri))

   The undergraduate course categories currently categorized as Undergraduate (not an intern), Undergraduate intern, and Competition will be changed as follows:

   • Competition: Deleted.
     • Students previously in Competition will be moved to Undergraduate (without advisor).
   • Undergraduate (not an intern): Renamed to Undergraduate (without advisor).
   • Undergraduate intern: The name will be changed to Undergraduate (with advisor).

   Additionally, Undergraduate (not an intern) students will use a dedicated moana-u partition.

   Students transferring to Undergraduate intern should complete the transfer during the 2. Resource Upgrade and Affiliation Transfer Application Period.

4. [New] Dedicated Partition for High-Performance Computing Nodes (Effective March 13 (Fri))

   A separate dedicated partition will be applied to ariel-k, m, and n nodes.

   • Each dedicated partition will be allocated a maximum of 8 high-performance GPUs per node.
   • Each dedicated partition will operate concurrently with its own partition or QoS. This means that the number of GPUs available to general computing nodes will be deducted by the number of high-performance GPUs allocated.

5. [New] Compute Node Automated Dataset Management and Large-Capacity Dataset Registration for SSD Capacity Management (Registration Period: ~ March 12 (Thu), March 13 (Fri))

   To alleviate the inconvenience and management burden caused by the compute node SSD capacity issue last semester, dataset management and large-capacity dataset registration will be implemented starting this semester.

   The following policies apply to each cluster:

   • Ariel & Aurora
     • Temporary, small-capacity (<50GB) datasets should be stored in the /local_datasets folder. The /local_datasets folder will be completely emptied every three months, starting March 13th (Friday).
     • The /dataX/local_datasets/ folder primarily stores large datasets. You must fill out the Google Form every three months to register your datasets. Unregistered datasets will be deleted after the registration period.
     • Registration and deletion will occur every three months. Datasets uploaded between the deletion and the next registration period will not be deleted until the next registration period.
       • In other words, dataset registration = request to prevent deletion during dataset cleanup.
     • A link to the Google Form for registration will be provided later.
     • The Google Form must contain the following information:
       • Affiliation, cluster, directory name (regardless of SSD, enter the parent directory name), period, etc.
   • Moana
     • The /local_datasets folder will be completely emptied every three months, starting March 13th (Friday).
   • The first registration and deletion will take place in March. Any datasets not registered by March 12th will be deleted from the /dataX/local_datasets/ folder on March 13th.
