For example: - 3D renders - video encoding - software compilation The CPU and GPU resources are being used by said task - maybe for hours - when you would like to use the system for something else. With Nyrna you can suspend that program, freeing up the resources (excluding RAM) until the process is resumed, without losing where you were - like the middle of a long job, or a gaming session between save points. --- Nyrna works on Linux with X11 and Microsoft Windows.

While this is rare, it is a known possibility that Nyrna can do nothing about. Please make sure to **save** your data or game before attempting to use Nyrna. ## Install View install options on the [website](https://nyrna.merritt.codes/download). ## FAQ **Can I suspend to disk so that I can restore after reboot / free up RAM usage / etc?** Unfortunately no. [CRIU](https://criu.org/) looks very promising to allow us to do this (on Linux), however it [does not currently support suspending GUI applications](https://criu.org/X_applications). ## Troubleshooting If you use Microsoft Windows, issues are often resolved by running Nyrna as an administrator. ## Building See [BUILDING](BUILDING.md)
