I am running 3 Einstein@home tasks on my Linux laptop, but no SETI@home task. I have an astropulse task on my main Linux box, and another SETI@home task on my Solaris Virtual Machine, which it crunches slowly but reliably. It just finished a vlar. climateprediction.net has no jobs available and QMC@home hasn't started again from its new location in Bonn.
And yes, two Albert@home tasks on the main box. Test4Theory@home on all three.

This is to Matt et.al. An observation on the scheduling with astropulse units. I have a 6 core cpu w/ 570GTX system that runs out of units frequently because the 8Meg Astropulse downloads take an average of 7 hours or so to down load.

During that time the units will spend a lot of time without downloading any data but keeping the active task open for long periods before changing to retry status usually with a 3 to 5 hour retry time. If I get a number of Astropulse units in one download batch the total download rate gets so low that my system will run completely out of units to process.

I have removed the Astropulse software from the app file so the system no longer requests Astropulse units. Once I did that the download throughput is high enough that the cache is almost full so I only get 1 to 3 units per download cycle, if any at all.

I don't know if the data rates get so low because of the scheduler has issues with long download times or if this is a by product of the bandwidth limitation imposed by the router.

I hope these observations provide some useful information.

To Tcarey,

The problem with your downloads is network congestion problem. A work around for windows machines to the problem is in the following thread:

Thanks. I have downloaded the program and run it. We'll see how that works.
