    Elastic High Performance Computing:Log on to the E-HPC Portal

    Last Updated:Apr 01, 2026

    E-HPC Portal is a browser-based interface for day-to-day job management. Once logged on, you can submit jobs, query job status, and manage data.

    Limitations

    E-HPC Portal is not supported in the following scenarios:

    • Hybrid cloud clusters

    • Clusters that use the Sun Grid Engine (SGE) scheduler

    • Clusters whose operating system is not CentOS

    Prerequisites

    One-time cluster setup — verify these once when you set up the cluster:

    • Inbound access on port 12011 is allowed in the cluster's security group. Clusters added to an automatically created security group allow this by default. If your cluster uses a custom security group, add an inbound rule for port 12011.

    • The RAM role AliyunECSInstanceForEHPCRole is assigned to the management node. Clusters created in the new console have this role assigned automatically. For clusters created in the old console, assign the role manually.

    • The Web Portal addon is installed and configured. See Install and uninstall an addon.

    • A cluster user account exists. See Manage users.

    Before each logon — confirm:

    • The logon node is in the Running state.

    Log on to E-HPC Portal

    1. Open the E-HPC Portal logon page using one of the following methods:

      • Console: On the Cluster page of the new E-HPC console, find your cluster. In the Custom Services section, click Web Portal. > Note: If you are using the old console, click Experience the new version in the upper-right corner of the Cluster page to switch to the new console.

      • Direct URL: Enter the URL in your browser using the format https://<Public IP address of the cluster>:<Port number of the web portal>/portal/login — for example, https://118.31.XX.XX:12011/portal/login. The default port number of the web portal is 12011.

    2. Enter your username and password, select whether to save your logon information, and then click Log In.

      • If logon succeeds, you are redirected to the E-HPC Portal homepage, where you can:

        • Submit jobs — create and dispatch compute tasks to the cluster

        • Query jobs — monitor job status and view results

        • Manage data — upload, download, and organize files in the cluster storage

      • If logon fails, check the error message and resolve the reported issue.

    Note: If you remain inactive for more than one hour, E-HPC Portal ends your session. Log on again to continue.
