Hi Simon,

1. To use NVMe for a cylc8 suite in `site/archer2.rc` in the `[[HPC]]` section change platform from `archer2` to `archer2-nvme`. You will need to start the run from the beginning, you can’t switch a run part way through.

2. Yes prebuilds work in same way. This is FCM rather than Cylc.

3. To extend a run; change the run length, then restart it with `cylc play <suiteid>`. You may or may not have to manually trigger the first task in the next cycle. e.g. `cylc trigger u-dr157 //<cycle>/atmos_main`.

Cheers,  
Ros.
