Hi all,

Is there a method out there that can “save a hibernate state” to disk, and just permanently boot immediately into that state every time?

It would be OK to lose data used after this point. And ot would also be OK if it required building a custom image based on the hardware, similar to embedded systems.

The goal is to be able to, as quickly as possible, spin up a GPU server when needed, but without using suspend/resume.

Thanks.

    Pretty sure you just have to enable hibernation and give it a file to write to? Then just set your PC to go into hibernate on idle

    I kind of doubt you would have to change distros. What distro are you on now?

      For my two systems (pc and laptop)with 32GB RAM each it takes ~4 minutes to boot from hibernation.

      Which is expexted afaik.

      Thats the opposite of “instant”.

          No not really.

          It’s how long it takes to read 32GB from my swap. 170 MB/s continuous read speed ≈ 188 sec (3 min 8 sec) add the normal boot time to it (bios, grub, kernel initramfs) and you get the 4 minutes.

          When the system boots cold it doesn’t have to read 32GB, just 0.5-2GB maybe.
