Of the last eight HCC results in which my machine has participated, five of them contained an "error" or a "no reply"
 .Since the initial replication for each HCC result is two, that means that there is a failure rate of 5 out of 16, or 31% or so. If a scientist had a 70% survival rate for a cancer clinical she would be ecstatic; for a software program this is a dismal result. |

Talking about your machine, than that's a bad statistics warranting some serious testing and diagnostics. Visit out Start Here forum Useful Utilities FAQ for some like memtest86.
----------------------------------------Meantime, hit one of the 'Error' links in the Status Result page Status column and post the log so we can have a read of anything special. Now, if that was a general statistic of your 8 valid/pending validation, and 5 having a partner that had X Error and Y No reply, it must be your lucky streak. I just checked the last 7 I ran, all valid, and all had only 1 quorum partner, also valid. Of Pending validation i cant say anything , because I've got none listed. Of course, you'll have to take me on my word. Let us know and we look into it. [Added: Oh yes, knreed wrote a few days ago that the quorum 2 distribution required on average 2.2 results to be distributed to volunteers for the DDDT project. That's 10%. The error/no reply rate on HCC rate was lower as far as I can e remember.]

If a scientist had a 70% survival rate for a cancer clinical she would be ecstatic; for a software program this is a dismal result. Correct, except that it is not the software which is accountable for this failure rate. "No reply": what can the software do if the task is not started, or started too late, or there is no network connection, or if the machine owner is on vacation? This failure falls in the human error category, namely bad planning. "Error": HCC is one of the most stable projects currently. Personally I return hundreds of them every month, all valid, and WCG is validating between 50,000 and 60,000 every day. All running the same version of the program. Most probable reasons are - an unstable machine - the WU has been aborted by the member - rarely for this project but theoretically it could happen: bad input data. Last, for statistical analysis on so small samples it is OK to state facts, but it is rather careless to infer definitive conclusions or such a negative judgment. Cheers. Jean. |
