HPC Hub 0.2.0

HPC Hub 0.2.0, a desktop app for working on HPC clusters (Wulver, Yale Bouchet and SDSC Expanse). Still an early build, so expect rough edges.

What's new

• Terminals: a timeline down the side of each terminal to scroll back through the whole session, with marks you can name and jump to. Sessions keep 50,000 lines, tabs reconnect on their own after the connection drops, and the mouse wheel scrolls.
• Compute nodes do the work: while you have a job running, the app runs its commands on that node instead of the shared login node, several at once. It goes back to the login node when no job is running.
• Queues: a Limits tab in Usage shows the most each queue allows, read from Slurm, and the queue list shows time, cores, memory and cost for each queue.
• Maintenance: a warning when a job you ask for would run into booked maintenance, with the choice to shorten it or keep it and wait.
• Report a problem: errors now carry a Report button. You see exactly what will be sent, with personal details removed, and nothing leaves until you press Send.
• Agents: model, effort and permission mode are dropdowns.
• Fixes: SDSC usage now counts SUs correctly, Backup's scan works in the installed app and reuses your running node, and Projects finds terminals in linked folders.

Which file to download

System	File
Windows 10 or 11	HPC-Hub_0.2.0_windows_x64-setup.exe (or the .msi)
Mac with Apple silicon (M1 or newer)	HPC-Hub_0.2.0_macos_apple-silicon.dmg
Ubuntu, Debian	HPC-Hub_0.2.0_linux_amd64.deb
Fedora, RHEL	HPC-Hub_0.2.0_linux_x86_64.rpm
Any other Linux	HPC-Hub_0.2.0_linux_x86_64.AppImage

First launch

The installers are not signed yet, so your system will warn you once.

• Windows: on the blue SmartScreen window, choose More info, then Run anyway.
• Mac: open the app once with right click, then Open. If macOS says the app is damaged, run xattr -dr com.apple.quarantine "/Applications/HPC Hub.app".
• AppImage: make it runnable with chmod +x HPC-Hub_0.2.0_linux_x86_64.AppImage.
• Read aloud with the .deb or .rpm needs the GStreamer plugins your system already ships (gstreamer1.0-plugins-good on Ubuntu). The AppImage brings its own.

The Android app is not part of this release yet.

Updated Nov 6: new Windows installers fix a sign-in error ("connect to host ... No such file or directory") when a picked SSH key file is gone.
