Project 6012: (Run 2 Clone 262 Gen 13)

Another failed a3core WU early in the folding. This one did not make it to 4%. I will have to remember this as Black Sunday.

I attempted to return the "remains" to Stanford, but it failed. Apparently, the Client is in such a rush to "fail" that it does not write to the work files correctly. Outcome is no info transferred to PG by the formal route and no possibility of any points credited, however meager. Log file covering the return attempt is as follows:

The AS, in its wisdom, resent the same WU to me. It failed at the same point (less than 4%) that it did on my first try.

The only change seems to be that the Client was able to write to the Work files such that a return to Stanford of the remains was possible.

The Log file follows:

I have no idea as to why my computer has gone "UNSTABLE". I run a fan application that controls and reports on the core temperature. I run it less than 150F and there does not seem to have been any problem. I check it frequently. It displays continuously.

I am not interested in going on a "wild goose" chase but are there any checks that I should do at this time to prove or disprove this charge of instability?

Guidance requested.

As I think about it, I believe the fact that my computer can run and rerun the same WU and bring it to failure at exactly the same point in each run is prima facie evidence of ideal stability on the part of the computer. An unstable computer, by definition, would produce somewhat randomized results. Perhaps I do not understand UNSTABLE in computerese....
