27th of January

Farm status
Intel GPUs
All running Asteroids and Seti work

Nvidia GPUs
Two running Einstein gravity wave work. Two off.

Raspberry Pis
Seven running Einstein BRP4 work

For news on the Raspberry Pis see Marks Rpi Cluster

Its been hot and humid and a few drops of rain. Too hot to run the farm. Today was a bit of a break in the weather so I have most of the farm running. The rest of this week is looking like it will be hot and humid so I don't expect to get much work done.

Project news - Seti
The project increased the allowed number of work units per computer. That promptly blew out the size of the database with the number of work units "out in the field". Last week they limited the result creation rate in order to get it back down in size. The project needs to fit the entire database table into memory and the machine already has the maximum amount of memory that it can hold. They resized the table last week but we still seem to have issues getting work.

In addition to database issues Seti@home did a fund raiser to replace the 120 x 2TB disk drives with 26 x 16TB disk drives (two are spares). It was supposed to run for 2 weeks but met its target in the first week.

New year. New decade

Farm status
Intel GPUs
All off

Nvidia GPUs
All running Einstein gravity wave work (on CPU)

Raspberry Pis
Two running, the rest are off.

New year
As another year ticks by and we're still crunching. Recently I've been looking at an industrial unit but the prices are too high in Sydney. Maybe something further away.

The bush fires keep effecting the air quality. The air quality and temperatures effect the ability to run the computers. Fortunately I haven't been directly impacted by the fires.

I mentioned in my 24th of November post that I made an offer to fund the SuperHost idea but I had no feedback from any of the key people in the BOINC world. I still haven't had any response. I have some money that I put aside for such development work but seeing as there is no interest in SuperHost I may as well use it for another purpose. I have two other things I was interested in:

1. A monitoring tool for a farm of BOINC machines that would highlight which machines need attention. The idea is to use it in conjunction with BOINCtasks. I did run the idea past Fred Efmer (the author of BT) but he felt that BT was able to issue alerts and wasn't inclined to do further development.

2. Power9 CPU support. Now these aren't exactly your high end desktop, they are more of a server grade CPU. Raptor computing make desktop and server grade machines along with IBM and probably a few more companies. The US has a couple of clusters (Summit and Sierra) running them. Debian Buster can run on them so there is already Linux and BOINC support. That just leaves the project apps needing to be ported to the ppc64el architecture as its known.

I expect there are more people who would be interested in point 1 than there are people who run a Power9 CPU so I am more inclined towards point 1.
