26th of July

Welcome back. After a bit of a break we're back crunching.

As I said in my last post everything was off while I was away. Everything powered up just fine, well the half of the farm that I have tried so far. I still haven't powered up the Nvidia GPU machines yet. There were the usual patches to apply, so that took a bit of time and there was a new alpha-test version of BOINC, so I installed that on one machine. No problems so far for the Intel GPU machines.

The Parallella's came up fine and most of the Raspberry Pi's did except one. I did an update on it and then it refused to boot. I had to re-image the SD card with an old backup and then did another update which seems to have fixed it and also gave me the alpha-test BOINC client. So far its behaving.

I will update the Nvidia GPU machines when I get time. At the moment the Intel GPU machines are doing ClimatePrediction work which hogs the computer until its done. They are the EU regional models which are fairly quick by their standards at 44 hours each. Once they are through I will be concentrating on Seti work as I still haven't got the credits up to the other projects yet, only about another 5 million needed. The Parallella's and Raspberry Pi's crunch Einstein work.

As seems to be usual with large files the ClimatePrediction work get stuck uploading so I have had to use the old dial-up to get the stuck files through. That takes a bit of baby-sitting and fiddling with settings.

Farm news
The farm is running down. Having reached a RAC (recent average credit) of 60,000 for Seti its going to be taking a break. I am travelling for a few weeks so the farm will be off.

I have been running one dual GTX660 machine and 5 Intel GPU machines exclusively doing Seti work for the last 3 or 4 weeks, so they can catch up to the other projects. Its currently around 19.1 million with the target being 20 million. The Parallellas and the Raspberry Pi's have been running Einstein work.

The first Pi has been regularly locking up, but its running kernel 3.12.22 and the others have 3.12.20 and they work fine. It also has a 16Gb SD card and the others have 8Gb cards, none of which should make any difference.

I spoke with my usual computer shop regarding the Haswell-E CPU's but they have no news at this point so maybe when I get back they will know more. It also looks like the latest Nvidia GPU's will be delayed so no upgrades in that area either.

Farm news
The Intel-GPU machines are all running Seti work. I also have the dual GTX660 equipped machine running Seti. I am currently on 18.3 million credits as I write this. The aim is to get to 20 million credits as Seti has fallen behind some of the other projects. The Parallella's and Raspberry Pi's are doing Einstein work.

We got a bunch of windows updates this week so I have been running around this morning getting all the machines up to date. Its takes a bit of time to get through all of them.

Debian Jessie also had a number of updates so the Raspberry Pi's got updated as well. It also gave them BOINC 7.3.19 which I have been running on the Windows machines for a while.

CPU upgrades
It seems there are some newer Intel i7 chips due out soon. The Haswell-E series are expected to be released in Q2 this year. I still have a couple of i7-970 machines that being the oldest of the number crunchers are due for replacement. There is talk of 8 core (16 thread) CPU's in the line up. Unfortunately it will mean new motherboards as well, so I will end up replacing both machines completely rather than reusing parts.

Farm news
Its turned a bit cooler so I have managed to get a few more machines up and running. The GPUgrid crunchers were running and they promptly trashed 16 work units each. Not my fault though they are bad work units and all the Windows users are failing them, so they pretty much are all flagged as bad work units apart from the few that get picked up by Linux users.

The Intel-GPU cluster continue to do Seti work with one finishing off its ClimatePrediction work units. The CPDN work units have about 62 hours to go and there doesn't appear to be any more work from them. Once its finished i'll get it onto Seti work as well.

The 60mm fans arrived in a 60cm box with a lot of brown paper for padding. I think they used a larger box to justify the $44 delivery fee. One has been put onto the Raspberry Pi that was looking rather naked with the 60mm hole in the top. The other two are spares at the moment.

They continue to crunch. I've had one lock up after about a week of running. The only solution is to unplug the power connector, wait about 10 seconds and plug it back in again. I am not too sure why they aren't stable as the Pi's run for months without needing any intervention.
