Millette" <[EMAIL PROTECTED]> Subject: Mersenne: Error writing intermediate file: rX250423 - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I am running an LL test and was probably very low on hd space for a short while and noticed this error: "Error writing intermediate file: rX250423" The equivalent p and q files seem to be written correctly, and the program is going ahead with more iterations. I checked the faq (btw, the footer of the list messages is misleading: the faq it points to is 404) on the http://www.mersenne.org/ site. I also googled and found an old 1998 message in a mailing list archive. Only a question, no answer. Since I'm almost 10% done, I was wondering if it's ok to continue, or would it be safer to start over? I guess prime95 would have automatically stopped, but I just want to be sure :) Oh, happy new year! P.S.: sorry if this is a dupe, seems like I wasn't subscribed anymore when I sent the mail the first time. - - -- Robin Y. Millette (aka Lord D.

I still have a few questions though... Brian J.

It's been about a day since my "incident". I made a lot of free space available yesterday. I see both qXxxxxxx and pXxxxxxx files, but still no rXxxxxxx. Should it reappear? With my settings, both files are updated every 30 minutes or so. Searching the archives earlier, this is the first clear response I've seen. Obviously, since I wouldn't be asking again :) Thanks Brian for clearing up the matter! - - -- Robin Y. Millette (aka Lord D.

Although the currently available ones work better on AMD64 CPUs than on an Athlon XP per clock, there are still possibilities to speed them up. But that means a lot of work or even totally new software. So they won't be available in the next weeks. I'll write another message with details about my current findings.

Is any statistix on double-check mismatches available? How often this happens? If my result get mismatch with some other's will I get any notice about that? Can I learn which of my results were confirmed by others? P.S. Having periodical problems with overheating (coolers become dusty) causing ``roundoff'' etc. hardware errors in mprime, I don't much believe in computational results unless they're confirmed by several parties. BTW, how error-proof is mprime ?
