Off topic discussion • Re: A bit of Raspberry with 144C/288T

P.S:
The 2^43 bits allow to store two 2^21×2^21 size game of life configurations, allowing to play 2,097,152×2,097,152 board game of life — perhaps I will program such code later with openmp.

Hopefully I'll have time to work on the $1000 prize traveling salesman problem soon. Right now I've been fighting with computer troubles.

• Before I enabled extra redundancy the server with ECC errors crashed enough to corrupt the drive pool and turn it read-only.
• While migrating everyone's homes, I used the unscheduled downtime to upgrade the Nvidia drivers.
• The 580 series supports the V100 GPUs and my tests passed.
• After closing the maintenance window I discovered Julia insists on CUDA 13 when it sees the 580 driver but CUDA 13 doesn't support the V100. Next time I'll test Julia.
• I decided to experiment with Julia, CUDA 12.9 and the 575 driver on a test system in preparation for another maintenance window. The test system lost a hard disk and IPMI locked up.
• Fortunately, that computer is in the fishbowl so same-day physical access was possible.
• The command "ipmitool mc reset cold" is new for the day. I'm surprised a watchdog didn't perform the reset automatically. It seems watchkittens are useless.

Left to do is replacing the hard drive, rebuilding the pool, checking Julia works with CUDA 12.9 and then making the same fix to the other systems. I decided to eat ice-cream instead.
