Error reading intermediate file - Page 2

GP2 · 2003-12-15, 19:22

If you've restarted the test for the same exponent, can you tell us:

Do the files pJxxxxxx and qJxxxxxx now exist?

If you stop and reboot normally (rather than a crash), does the program find and read these files correctly, instead of restarting from zero? Maybe you should make copies of these files under different names before you test this.

Which directory are you running under? Is it C:\Program Files\Prime95\ (assuming you're running Windows) or some other directory?

I restarted the same exponent and now files pJxxxxxx and qJxxxxxx exist. I run Prime95 from C:\Program Files\Prime95\.

I add InterimFiles=1000000 in prime.ini. Now I copy pJxxxxxx and qJxxxxxx files and pJxxxxxx.00x files in one back up folder, just in case something similar happens again.

Now everything runs fine and I reach 3m iterations (only 3m, when I take into account that today I should finish this exponent, if there was no crashing issue

).

Well, in a couple of days you will have forgotten that unfortunate event...
Some months ago, I was nearly finishing a 13M exponent, and while messing around with some files I accidentaly erased the partial pxxxxx and qxxxxxx files. I obviously had to start from scratch

. Felt like slapping myself in the face

You are right. I will forget this once I complete this exponent. Especialy if at the end I find those wonderful words:

New Mersenne Prime Found

After my home machine crashed several more times (especially when running Prime95, but not only then) I finaly perform memory test and torture test.

Memory test finds several 1000 errors (5332 in test 1, 16 in test 2, 19070 in test 3, 730 in test 6, 307 in test 7, 23826 in test 8, 3702 in test 9, 12750 in test 10).

Torture test find error after few seconds of running. Message was:
FATAL ERROR: Reading from temp file; 1 errors, 0 warning

So, it seems that my home machine is a very bad one. What could cause that errors?

I will bring my machine back to dealer, as I still have guarantee on it. Any idea what they will have to do to it?

Good thing is that 3 other machine works fine (at least it looks like they do).

Just tell them the tests you ran, and let them worry about fixing or replacing it.

Bring in the floppy or CD-ROM that you put Memtest86 on, and bring it to the store and show them if necessary.

edorajh · 2003-12-19, 20:08

Thanks. I will do that. I call them today to make an appointment, just to find out they are going to collective holiday. They will open January 12th! What an excellent customer service!

Since your dealer is closed, try switching off, disconnecting from power, opening up the case, and reseating all memory. I.e. just push it in firmly. If you are lucky that may fix the issues.

While you are in there, blow out any dust and make sure that the CPU and all cables are well-seated.

Be sure to earth (ground) yourself while doing this. You can buy an earthing strap, but it is probably enough just to hold on to bright (unpainted) metal while working.

I couldn't stand to look my machine stand off until 12th January, so I try TF work with this machine. It works fine for a whole day.

It will finish first TF in a few hours.

Is it possible that machine could have problems with LL tests but to work fine on TF?

garo · 2003-12-26, 07:51

Yes! very possible. TF stresses the CPU a lot less than an LL test. As a guarantee it may be a good idea to run TFs on exponents with known factors and then check if all the factors were foudn or not.

Going right back to edorajh's original posting, I had the problem some months ago (Athlon, WinXP). Tried asking all sorts of people, including posts here if I remember rightly, and could not identify any kind of hardware problem.

What I did establish after a while was that the problem occurred if and only if there was a prime.spl file in the Prime95 directory, i.e. if there was information to be communicated to the GIMPS server but a connection had not been established before a system restart. The problem occured after normal restarts, not just crashes.

This doesn't for me explain the problem, but it might help to avoid it.
