Tonight we just finished the "earth hour". I switched off the power in the house for an hour. For light I had a couple of candles going. Its now over so the power is on and so are the computers.
This week has had its ups and downs.
On the up side Darth Maul joined the farm and is crunching away.
On the down side the Seti@home file server had a hard disk failure and hasn't been sending out any work for a while. It is back in a rather limited fashon and producing small amounts of work units. The Einstein@home file server also failed and so its not downloading or uploading anything and the website is gone too. That leaves GPUgrid and Orbit@home for work. GPUgrid is working but not all my machines have GPU's. Orbit hasn't had any work for months. So basically the farm is almost out of work. I have attached one machine to Climateprediction but it wants to download over 150Mb to get started, so that will have to wait until my ISP's off-peak hours (1am to 7am).
I have continued BOINC testing. The current version is looking stable enough now to be released. I have 6.6.18 on one machine and 6.6.17 on all the others.

Darth Maul pictures #1
A close-up shot of Darth Maul and the front panel. Thats a fan grill behind him, but it doesn't have a fan installed as the inside of the case doesn't get that hot.
And here is the insides looking towards the back of the case to give you an idea how big the heatsink/fan is.
The CPU doesn't seem to run that hot. Not suprising considering the size of the heatsink/fan.
The graphics cards on the other hand run around 70+ degrees, and thats when I ramp up the fan speed manually. The nVidia drivers are not too good at increasing fan speeds while running cuda tasks. I'm currently running 182.06 drivers.

Some more pictures of Darth Maul, complete with figurine
Here are some more pictures of inside. The motherboard is an ASUS P6T, Intel core i7-920 CPU, Thermalright ultra120 heatsink/fan and 3Gb of Corsair DDR3 RAM. In the pci-e slots there are a couple of Palit GTX26o graphics cards.

Introducing Darth Maul
Well the KFSN4 went off to the computer shop and came back as a P6T sporting a zippy new Intel i7-920 and 3Gb of RAM. It also has a couple of GTX260-216 video cards. Its known as Darth Maul.
I had a few teething problems installing XP which turned out to be a dud CD. Used a different CD and that fixed it. Applied SP3, download latest 74Mb of fixes from Microsoft and its ready to roll.
Installed BOINC and picked up a couple of GPUgrid wu and it seemed happy. It then picked up some Einstein work, cpu fans all ramped up and then it crashed. The shop had OC'ed it to 3.9Ghz. So hop into the BIOS, reset to factory defaults and off we go again at 2.67Ghz this time. Seems to be stable now.
Here is the GPU-Z screen shot of one of the 2 GTX260-216 cards.
Here is the CPU-Z screen shot of the i7-920 after resetting to factory defaults.
And here is the BOINC manager showing all the tasks.
Lastly I had to go and update the flops counts in the Seti app_info to reflect the different speed compared to my usual quad-core machines. It hasn't picked up any Seti work yet so we'll see how much of a speed difference it makes.
