GTX570 update

After yesterdays run showing that you can fry eggs on these things I decided to try Evga Precision. This is the default settings, with the fan speed on Auto. As you can see the GTX570 could double as a cooking appliance.


After taking this screen shot I decided to ramp the fan speed up to 75%, which brought the temperature down. I cut the fan speed to 70% and it seems to be holding the GPU temp at 77 degrees C. The room temp is 28 degrees next to the computer

This is the factory standard model. I didn't get an overclocked GTX570 because of the heat, so I hate to think how they perform.

GTX570

The GTX570 arrived and has been installed in Spock.

It has run a GPUgrid work unit so far. The GTX570 completed a HIVPR_unbound work unit in 14,019 seconds compared to a GTX295 that did it in 27,728 seconds. The GTX295 can run two work units at a time. They used a different GPUgrid app (6.13/cuda 3.1 on the GTX570, 6.12/cuda 3.0 on the GTX295), so it may be more like comparing apples with oranges.

GPU temps got up to 85 degrees which was rather warm.

The GTX295 is still the best value for number crunching at this point, although that may change when a cuda 3.2 GPUgrid app becomes available.

None this week.


GTX570 ordered
I've ordered a GTX570 to see how it performs. It should arrive next week.


Project news - Seti
They are back up and running. Maul picked up a fair bit of cuda work and is busily working its way through it. Its got enough for a couple of days.


Maul
As mentioned above its got a heap of cuda work from Seti. Its also got a heap of Einstein cpu work to get through. Fortunately its finished all the Seti cpu work, so all cores can concentrate on clearing the backlog. It doesn't help that its usually off during the day due to the heat.

Milestones
Nothing new this week


BOINC testing
We're up to 6.12.8 this week. So far no issues. They are looking at this one being released soon.


Project news - Seti
New servers have been switched over, except for the science database one (they were copying it from the old machine just before the weekend). We got some resends of old timed-out work on Friday. I managed to get 2 work units, which were promptly done and returned.


Computing focus
Currently Einstein is the most reliable project.

Seti will come back on-line next week so I will be able to do some work on a couple of machines for it.

Climate Prediction I am trying to finish off the 3 remaining work units on 2 machines which usually get switched off during the day (due to the weather).

Orbit doesn't have any work currently.

GPUgrid have issues with their app that cause the machines to crash, so i'm not doing any work for them at the moment. Things aren't so good at the moment with their cuda 3.1 app crashing and their 10 hour work units. I might put old drivers on the 2 machines with GTX295's to see if that resolves their app issue.
