Hi,

Boinc thinks my computer has 2 processors due to hyper-threading.

If, let boinc run with both, the puter crashes all the time. However, if I limit boinc to 1 processor in a multi-processor system, its ok. ( as set in seti-preferences).

anybody else have this problem?

cheers

I was getting random crashing on a machine with hyper-threading. It seemed like it would happen if I exited BOINC and then restarted it. I started to reboot my machine if I needed to restart BOINC and the crashing seems to have stopped. The crashing may have had nothing to do with BOINC. I may just be on a lucky streak.

I have never had a crashed PC due to running BOINC of any version, and I have run BOINC since v3.xx. I have never had a crash since I built this PC back in July '04.

CPU - P4 2.8Ghz 1MB L2 Cache w/Hyper-Threading
MB - Asus P4P800 Deluxe w/800 FSB and Intel 865PE Chipset

Hi

looks like a hardware issue to me, most likely related to cooling or power supply.

Gordo,

I checked out your results from your 2.4 GHz machine with the two processors. It shows client errors like mine use to. What I was thinking was happening to me is I would shut down BOINC to play games or something. Then I would start it back up and everything would appear to be running fine. Sometimes I would come back several hours later and everything would be froze up. I would have to kill the power to shut down. Then when I would check my results it would show a bunch of results with errors like it wasn't operating correctly for several hours. About the same number of hours to the time I restarted BOINC. After that I tried to only restart BOINC by shutting down my computer and letting it start up with the start up. Like I say though, it may not be related to BOINC and I may be imagining the whole thing.

Hi Gordo:

I have the same problem with my computer. Initially BOINC ran ok with version 3.20 but since they upgraded BOINC the computer freezes up after a few seconds to a few hours requiring a manual reset to reboot the computer.

I have brought the computer back to the store twice and they say there is nothing wrong with the system. According to them it runs Prime95, and BOINC without freezing up while in their care. They suggest that its something in my home that is causing the problem. So far as I’m concerned they simple don’t want to fix it on warranty or too dumb to figure out the problem. Most likely both.

Here are the stats on my computer:
Intel Pentium 4HT, 2600MHz (13 x 200), Northwood HyperThreading
ASUS P4PE-X, 11/10/2003 – I845PE / ICH4 / IT8708 – P4PE-X
Micron Tech 16VDDT6464AG-265C4, 514MB, PC2100 (133MHz)
Southbridge: Chipset Intel Brookdale i845PE, revision 03
Northbridge: Intel 82801DB, ICH4

I obtained the above information using Lavalys’ Everest Home Edition 1.51. It’s free.

Form interchanging parts from a 2.8GHz P4 with an ASUS P4PE2-x motherboard and 1GB ram, I have narrowed down the problem to the ASUS P4PE-X motherboard. I think the motherboard has a bug that doesn’t handle the use of 2 CPUs properly. Why would ASUS have come out with a P4PE2-X motherboard if there were nothing wrong with the P4PE-X?

In the mean time, I have set the number of CPUs to 1 in my preferences. Seems to work so far.

In the next week or 2, I will replace the motherboard and hopefully get back to using 2 CPUs.

Since my earlier post, I have managed to find a few utility programs on the Intel web site to help diagnose your computer system if you are having problems with running BOINC with multiple CPUs. These are OS specific.

Hyper-Threading Technology Test Utility
Intel® Processor Identification Utility

http://downloadfinder.intel.com/scripts-df/Product_Search.asp?Prod_nm=chipset*ID*utility

Intel® Chipset Identification Utility
Intel® Chipset Software Installation Utility

Running the Hyper-Threading Technology Test Utility, it discovered that the 845PE Chipset on my ASUS P4PE-X motherboard is defective confirming my earlier suspicions.

What OS are you using? If it's WinXP then its probably a hardware problem, like heat because BOINC fries your processor.

> because BOINC fries your processor.

Only if there is something wrong with your system.

I used to have a lot of faith in ASUS, then I purchased an A7N8X-VM/400.

As it turns out, they have a great ruddy stack of products with "A7N8X" in the name, and some of them are pretty wonderful. Some are poor, and a few, like the above named A7N8X-VM/400 are only suitable for use as landfill.

Hi Ned:

When you upgrade or buy a new computer once every few years you pretty well have to put your faith in the person selling you the computer. It’s almost impossible to keep on top of what works and what is garbage unless it’s your job to know.

So far as I know, BOINC is the only program that uses the Hyper-Threading Technology. And if it weren’t for BOINC, I would never have known that the Hyper-Threading Technology in the chipset in my computer was defective.

My best advice would be, before you pay for the computer and walk out the store, bring a copy of BOINC and some of your other favorite software and load it on the computer and take it for a serious 48 hour spin before pulling out your wallet.

Assuming of course that I purchase my machines already assembled.

Any propgramme that supports multiple CPUs will use HyperThreading.
