even though I have changed my preferences to: Keep enough work on disk to last between 0 and 0 days On multiprocessors, use at most 1 processors my dual Xeon (HT enabled) keeps downloading WU's as soon as the number of WU in the queue drops under 4 with the following entries in the stdout.txt: ---: Fewer active results than CPUs; requesting more work SETI@home: Requesting 1.000000 seconds of work is there a way to drain the queue without destroying the assigned WU's?? |

Till a better solution is implemented, one way that should work is increasing the disk-space-limits. If "Leave at least" is larger than your free space you will continue asking, but will not download more work. |

The reason that 0 to 0 does not work is to fix a multi proocessor bug. If a reasonable amount of time is set for the queue, and you have a slow multi processor computer (I have 2 dual 200Mhz machines in my mix) one of the CPUs is constantly starved unless a notice of an idle CPU is sent to the server. This notice is sent by incrementing the work time request to 1 second from 0 seconds. As you can see if a single processor requests 0 seconds with an idle CPU, the time is incremented to 1 second, and a WU is delivered. jm7 |
