LHC@home

Is there any reason that these two will not run together on a hyperthreaded computer? I tried on two computers and on both Boinc siezed and would not run either.

I'm running LHC & CPDN & Pirates & Seti sometimes all together on 3 HT PC's ... :)

I think you misunderstood.
He propably means running one instance of LHC and at the same time one of the other Projects.
If you tell boinc to use both HT processors you always have two instances of the same application running.
Unleast you have only one WU from one project left

I understood what he said Tank, if you set your Resource Preferences to 50/50 for each Project a P4 HT CPU will run 1 WU from each Project at the same time, at least all of my HT CPU's will anyway ...

My guess is the single-slot/GUI-freeze issue. While LHC wasn't handing out work, your multi-threaded CPU (which BOINC handles as an SMP system) was only processing CDPN. The GUI client has a bug in it where if only a single slot on a multi-slot-processing system has work, it becomes unresponsive as it goes into a tight, "runaway" loop on the idle slot (which consumes 100% load on that idle CPU).

Basically, Task Manager should show you that your CDPN work is being processed as normal and show boinc_gui.exe has using 50% CPU load. If that's the case, you can just leave it alone. If it really bugs you, exit the GUI client and use the CLI client and BOINCView (to monitor your progress).

Also you can change your global preferences to use one CPU while there is no additional work and continue use GUI client.

Opps my fault then. Never had this happening cause I have a prefered Project and the other is backup (when online).

Just to toss my oar in ...

On all 4 of my HT machines I have them attached to SETI@Home, cp.net, and LHC@Home. My buffer size is set to 4 days. So, I usually have a good supply of work. Each of the HT machines has one cp.net WU/Model and depending on their mood I will have two work units in process from the three projects.

Exactly which WU from which project switches to achieve the balance in the work load, which for me is equal for each project. The only oddity is that, of course, the two projects run their WU to completion while for cp.net I have still to run one WU to completion (though I am getting close with one ... only a day to go ...)

On the Macintosh I usually have one SETI@Home WU and one of the cp.net WU in progress almost all of the time. On occasion, I will have two WU from one project in work, but a split is more common ...
