ln5: 2022-03-24
Last week:
- Received hardware for a new home for snowflake.tpn; discussed OS configuration with dcf in private email
Next week:
- Install Debian 11 on new snowflake.tpn
- Possibly rack new snowflake.tpn, if I can get access and find time to do the transportation
Need help with:
- Input on urgency appreciated, for my planning
- Input on preferred CPU configuration, esp wrt HyperThreading -- lacking input before deployment in data centre, the machine will *not* have HT disabled and CPU bug mitigation will thus have to be carried out by the kernel
