Its been hot and humid. The loft where the machines are has been in the 28-31 degrees (C) range for the past 3 weeks. Yesterday we had a break from the heat and things cooled off a bit so I could get some of the machines going.

It was so hot one of the hard disk drives in the external disk enclosure stopped working. When I went to remove it I couldn't hold it because it was too hot. I left the enclosure off for a couple of days. Its now back on-line. It has an 80 or 90mm fan in the back of the enclosure but it doesn't seem to move much air.

I still have one GTX 1660 Ti to replace. The three GPU machines running at the moment have all been upgraded to RTX 3060 Ti and 850 watt power supplies.


Future plans
I am waiting to see how the PCIe gen5 and DDR5 transition pans out. DDR5 memory is particularly expensive and in short supply at the moment. I'll probably replace the Ryzen 5900X machines with whatever comes next from AMD. The Intel chips are too power hungry at the moment to consider, but time will tell. Intel are on a 10nm process where the next gen AMD chips are looking at 3nm so should be more power efficient.

PCIe gen5 doesn't help with the GPU's as the PCIe bus isn't a bottleneck. Switching to PCIe gen5 SSD's doesn't make much difference either, sure I/O is quicker but the compute nodes don't do that much I/O. DDR5 memory on the other hand could benefit the number crunching, particularly on the CPU-only machines.

I finally got around to updating the storage server to Debian bullseye. It was the last machine needing to be reinstalled.

I still have to update the GPU's in two of the Nvidia machines. They are sitting in boxes on the floor waiting for me to find the time. I was planning on doing that tomorrow but now I have been asked to do something else.

Christmas was hot but things finally cooled down a bit for boxing day so everything was off, even the Raspberry Pis were off! I haven't started up the x64 machines but the Pi's have all resumed crunching duties.

Rosetta seems to have some work again so I have been running the Ryzen 5900X's machines for it overnight.

I swapped disks in the Chia storage server and have resumed plotting, at least until I run out of disk space again. For news on my Chia farming see Marks Adventures in Chia

Next on my list is to upgrade the two remaining Nvidia GPU machines. I need to swap out the power supply and the GPU's. I have the parts.

Other news
The weather has been all over the place. Its been hot, its been wet and its been cool. At the moment its cool so I have a couple of the GPU running. Rosetta doesn't have any work (apart from python tasks) so there haven't been a need to use the CPU only machines. While they could run Einstein tasks on CPU its much quicker to use the GPU equipped machines.


Rumour has it
There is supposedly a 12GB RTX 3060 Ti on the way. There is also talk about a RTX 3060 Super and a re-released RTX 3090 Ti. I am not sure what, if any, changes they will offer.

The RTX 40xx series are expected to be released towards the end of 2022. See This video for a send-up of the 4090 and 4090 Ti. It might not be too far off with suggestions the 4090 may use 500 watts.
