The CMOS battery on my home PC died the day before yesterday. I replaced it yesterday with no prolems. I hade to go into the setup and reset the date and time, and what hard drives to look at. Then it booted up no problems and is working fine (appears to be anyway)

This morning I looked at boinc on it and I noticed that it thinks there is only 1 cpu in it (there is but it had (to the best of my memory) always shrubbed multiple shrubs at the same time). This morning it was only doing 1 at a time and that left me a bit confused.

Any thoughts? Am I losing it (more than usual)?

Its the hyper threading...

I was a Amd guy when those chips were out (still am until my next build) so I don't know how to enable that. I'm not sure if it is in bios or in Boinc.

It will be in the BIOS - location depending on the BIOS manufacturer, but typically in the Processor features section.

I guess I will have to go through the BIOS to find where to reset that then. Thanks. Any idea where that would be in a DELL XPS Gen 2?

Thankfully DELl has a decent website where you can lookup computers you have purchased from them. I just did and found the following:

Quote:
CPU Information

CPU Speed
The processor speed at which the computer boots.

Press the left- or right-arrow key to toggle the CPU Speed option between the resident processor's rated speed (the default speed) and a lower-compatibility speed. A change to this option takes effect immediately and no restart is necessary.

To toggle between the rated processor speed and the compatibility speed while the computer is running in real mode, press <Ctrl><Alt><\>. (For keyboards that do not use American English, press <Ctrl><Alt><#>.)

Bus Speed
The speed of the processor's system bus.

Processor ID
The manufacturer's identification code(s) for the installed processor.

Clock Speed
The core speed at which the processor(s) can operate.

Cache Size
The size of the processor's L2 cache.

Hyper-Threading
The setting that allows you to enables or disable Hyper-Threading technology for operating systems that support Hyper-Threading. The default setting is Disabled.

NOTE: If your computer has a processor capable of supporting Hyper-Threading, the Hyper-Threading option is the first selection in the list.


Since hyperthreading is disabled by default and the CMOS battery died, I think it is safe to presume that the Hyper-threading is off....

It was the hyperthreading! Thanks! I found it in the BIOS, right where DELL said it would be and fixed it. Now I am shrubbing 2 WUs at once again! Thanks!

Does this mean you'll now double your output?

If so, I'll have to watch out!! Laughing

Hardly. Laughing Your lead is safe. Since I had to replace the CMOS battery my PC at home was down for 1 day and at half power for another. It is back to where it was before. Hopefully production will improve a bit.

iirc, Shrubbers using hyperthreading decided that the extra cpu cycles required to make hyperthreading work was counterproductive. The newer boinc clients might have over come the problem, You'd just have to try it both ways to see...

Just a simple coin battery. Or a short power outage as was the case with me. Set the date 6 months ahead and see what hapens. LOL Utter and complete mayhem My Boinc Manager on those machines is projected ahead and the lines reverse on themselves. Really strange looking in the stats manager. #ni-2 http://boincstats.com/stats/boinc_user_graph.php?pr=bo&id=755284[/quote]
