Rosetta ran out of work. I've picked up a couple of resends for failed tasks but that is all they've had for the last two weeks. The farm has been running Einstein work.

One of the computer shops I purchase from got hacked last week so I had to cancel my credit card. I've been waiting for a replacement which is super annoying due to the Black Friday sales being a great time to pick up a bargain and I can't buy anything online at the moment.


Ampere Altra
I fired up the Altra for a couple of hours this weekend. Its super noisy being a 2U server so I have to wait until I have the house to myself before using it. It ran 76 Einstein BRP4 work units in an hour. Two of the work units got a download error and I have reserved two CPU cores for the machine to use which is why it didn't do 80 of them.

I found out the front drive bays are SAS by trial and error. I tried an U2 SSD which wasn't found (but the drive bay power LED came on), then a SATA 2.5" HDD which also wasn't found (no LED's) and finally a 300GB SAS 2.5" HDD which was found and I re-partitioned and re-formatted. Given the capacity I won't be using it in there, its much too small. I will have to purchase some larger capacity drives. Seagate make a 960GB SAS SSD which sells for 750 AUD or for about the same price I can get a 2.4TB (10k RPM) HDD. It has an M2 SSD on the motherboard as the boot drive but it will wear out fairly quickly if I use it for number crunching.

I still haven't tried running Rosetta@home as I would need it to run for 8 hours at least. Einstein also has a Gamma Ray search app that the Pi4's are taking 27 hours to complete. The Altra should be able to do them in around 10-12 hours but I can't leave it running that long at home.
