Dust buildup in your fans can usually cause a system to slow down. Try opening the case and using a can of compressed air to blow out all the dust in the CPU fan and in the GPU fan as well and see if that helps.

It looked like you had a couple of VLAR tasks on there too. Those will slow things down a lot when you get them especially on Cuda.

It is suggestable that you run the VLAR optimized CUDA app if you are worried that your scans are taking too long. It will prevent your computer from processing the "very-low-angle-range" tasks that increase processing time.

How can I tell if a WU is a VLAR?


If it takes a really long time to process its a VLAR.
2 Hours would be a normal work unit (less if its a shortie)
8-10 hours is a VLAR.

That pretty much depends on your machine.

A better way would be to search for the string <true_angle_range> in the projects\setiathome.berkeley.edu directory. Values found there below 0.05 are considered VLAR (I think).

[edit] With windows, one way to find the angle range would be
find "true_angle" *.*.*.*
in the abovementioned folder; with *nix, a similar grep command with a numeric file mask.[/edit]
