Hello,
I have notice on my older Intel P3 based rigs that HCC WUs take a really long time compared to other projects. After reporting they also overclaim credit. Is this because HCC WUs use SSE2 to process the data? I have never had one crash on a P3 they just take a really long time. Anyone know what's going on? Just curious. Thanks in advance First post! ![]() |

The original credit idea was based on "effort", so don't worry about overclaiming on a slow computer. If you're lucky, you'll get two slow computers working on the same one.
---------------------------------------- We should not be using special hardware language extensions on these workunits. Perhaps it was just a strange workunit. I have just moved the computers to HCC because they are SHORT workunits now. (at least until I get a look at the new DDD-T)On the same fast computer, I just finished a couple of HCC in less than 5 hours each. The new FAAH version 6.03 was over 20 hours and over 9 hours by comparison. I don't think you'd want to mess with those. The PIII is getting to be borderline, though, for some of the newly intensive work.

We should not be using special hardware language extensions on these workunits. Perhaps it was just a strange workunit. Actually, SSE extensions are no longer special. x87 floating point math is special, as it is now obsolete. Both Intal and AMD have fully depricated x87 floating point, and it isn't even allowed in Vista compliant applications. |

On a P3/866, HCC WUs average about 27 hours, while HPF2 average is about 31 hours. HPF2 takes about 1.15 times as long for 2.25 times the credit! Using a P3 on HCC is appears to be extremely inefficient and hence a really bad idea. (see my table on this thread) |

I am running Rice on two PIII's but staying away from HCC, which I run on two Core 2 Duos. HCC just cannot get done in time on my PIII's.
----------------------------------------I am looking for direction as to how two run just Rice on the older machines but both Rice and HCC on the newer models. I was told to set up a separate profile but I want to keep everything on one CPID, so I am unsure as to how to go about that. >>RSM |

Same member name, just create the school, work or home BOINC profile (My Grid > Device Manager > Device Profiles), select the project and associate that profile in Device Manager with any of the devices of choice. It all stays under same member, thus under same CPID (long as you don't change the email address).

Thanks for the clarification. The two devices, the PIII's do not yet have any results since I re-attached to WCG on them. I assume that I need to wait until they show up n My Devices after achieving a result?

No, they appear immediately in Device Manager. It's the My Devices where they don't show until a statistics update ran and those devices having reported a result in the previous day segment. They fall off the screen again if no result comes through about 7 or 14 days after last result, but you can make them visible again with the filter options.
